wmf_pressure_cooker_review_lid2If Kuhn Rikon is known as the Mercedes of pressure cookers, then WMF is the BMW- in a class of its own with emphasis on quality, usability and durability.  The WMF Perfect Plus pressure cooker has a couple of features that are brilliant – like a sound to let you know it’s gone into over-pressure and a completely new way to release it (see “Innovative Pressure Release” in the Performance section).

Pressure Cooker Review: WMF Perfect Plus 6.5 L

We were a little apprehensive about reviewing the WMF, after our experience with another premium cooker. We were convinced that innovation and sophistication comes at the cost of durability and consistency but, thankfully, the WMF Perfect Plus proved us wrong.

A little PSI Confusion

In America, WMF pressure cookers are commonly, and inaccurately, referred to as the “13psi cooker” – with a caveat that it’s 2 psi less powerful than “15 psi” cookers.  If this were true, this large difference in operating pressure would require the cook to make adjustments to the cooking times from recipes written for “15psi” cookers by a minute or two – depending on the food.

But it’s not true.

Most pressure cookers that say they operate at “15 psi” actually cook at 14.5 psi (the number is rounded up). WMF pressure cookers actually operate at 13.8 psi .  The true difference in operating pressure between the two is less than a  point, not two,  making any adjustments to cooking times come down to seconds not minutes – in other words, negligible.

Features: (4.75 out of 5 stars)

The WMF Perfect Plus gets a very small ding from us in this category because the handle on the lid not self-locking like so many of it’s modern peers.  This means that once the lid is in place, the cook needs to remember to slide the handle lock closed.

  • All-in One Removable handle and valve mechanism – The handle, and pressure valve are encased in a single unit.  It can be easily removed for cleaning with the move of a button.  The handle clicks back into the correct position by hooking onto the metal handle guide on the lid.
  • In-handle pressure release – Ensures the cook not come in contact with the super-heated lid or sides of the cooker to release pressure.  The whole operation can be done near the tip of the long handle keeping fingers, wrists and fore-arms of the absent-minded cook safe.
  •  Over-pressure Alert Sound – When the cooker has reached pressure but cook has forgotten to turn down the heat a harmonic tooting sound will begin to play softly to alert the cook to lower the heat to and begin timing their pressure cooking.  Should the cook not move quickly enough to do this the sound will crescendo into a more urgent loud toot.
  • Fill Lines – Capacity marks inside the pot indicate 1/3 full (we don’t know why), 1/2 full (maximum for cooking grains, beans and other foamy foods) and 2/3 full (maximum for regular pressure cooking).

wmf_pressure_cooker_review_features

Safety:(5 out of 5 stars)

The WMF Perfect Plus has the standard set of redundant safety features, comparable to its peers.  Instead of a locking lid, it has an Automatic Release Handle, which forces the cooker to release pressure when the cook attempts to unlock and open the cooker.

  1.  Automatic Release Handle – The pressure cooker cannot be opened without releasing pressure.  Moving the handle slide (aka pressure release) to the “open” position forces a pressure release ensuring the cooker cannot be opened while the contents are under pressure.
  2. Primary over-pressure release valve – Integrated in the pressure signal, activates to release pressure if the pressure cooker reaches 16 PSI  it begins to release excess pressure and make a “tooting sound”.
  3. Secondary safety valve – Located across the lid from the primary pressure valve, a small silicone plug that activates in case the primary should be obstructed or not working properly to release pressure.
  4. Safety Gasket vent – The safety vent is a cut-out on the lid and comes into action in case any of the previous safety measures were to fail. The gasket will buckle and allow pressure (and some of the contents of the pressure cooker) down the sides of the pressure cooker.  The cook should always point this cut-out in the rim away from him while operating the pressure cooker.

Performance: (4.5 of 5 stars)

wmf_safety_plugWe were fascinated by the silicone plug in the lid-  ‘cmon, it looks like the little button-nose of a puppy!  On closer inspection, and discussion with WMF, we discovered that it’s more than just a cute safety mechanism (see section above)  but plays an integral role of assisting the pressure cooker to build and release pressure.  This silicone plug contains a little metal ball that is pushed from one chamber to the other to vent, maintain or release pressure.

Pressure Indicator
pressure_selectorThe WMF Perfect plus pressure regulator is integrated right in the pressure cooker handle.

The indicator bar communicates what is happening inside the cooker. It’s the blue circle nested in the part of the handle that covers the lid of the pressure cooker. When the cooker is in use, the indicator rises out of its housing to display a brightly colored cylinder with a series of rings.

When the circle is  level in the the handle, it means that there is no pressure in the cooker.

The first ring, in  yellow, informs the cook that pressure is building. A secondary lock inside the handle clicks closed in the cooker assuring that the lid cannot be opened by accident.

The next ring, in orange, signifies that “low pressure” has been reached.

The last ring, also in orange,  means that “high pressure” has been reached.

The advantage of an indicator bar vs. a pressure selector, is that the cook can turn the heat down while the bar is in any position to maintain that pressure. For example, anywhere between the first or second ring for “Medium Pressure” or just after the yellow ring  for “Extra Low” pressure.

Toot!
Should the cook have their back turned or have stepped away while the cooker is building pressure, once the signal raises past the second ring and goes into over-pressure it begins to make a soft harmonic tooting sound, which gradually becomes more persistent until the cook realizes that the heat must be turned down.  This sound is loud enough that it can be heard outside the house and into the street (just ask our neighbors!)  It quickly snaps the cook into action.

A common complaint of modern pressure cookers is that they are either too quiet – and stealthily vent out all the cooking liquid while the cook isn’t looking- or too complicated – with detachable timers that work in a non-standard proprietary way.  We can assure you that this cooker  has neither of those problems!

Under Pressure
While the WMF needed just a tad more heat than the Kuhn Rikon to maintain pressure (knob position 1.7 vs. 1.6), it was a little difficult to gauge the evaporation rate. On the first test the WMF preformed terribly (but that’s because we waited until it started to toot). Subsequent tests, where we turned down the heat just-after we saw the second ring but before it tooted were inconsistent enough that we had to test this cooker six times instead of the usual three (one test was an eye-brow raising 1.5% evaporation, while another was nearly 5%). Overall, the average evaporation is comparable to its peers.  Our test recipes  like a risotto, tomato sauce, potatoes, beans and dessert all turned out perfectly.

wmf_perfect_plus_test

Innovative Pressure Release 
The way this cooker releases pressure is brilliant. Careful cooks release pressure from their cookers with tongs, wooden spoons, spatulas, oven mitts or whatever is at hand to extend their reach over the super-heated lid of the cooker to press a button or switch a liver to trigger a pressure release while keeping their fingers out of the way of escaping vapor.  None of this additional protection is necessary when it’s time to release pressure from the WMF Perfect Plus because the pressure release lever is near the tip of the long handle – away from the hot lid or spray of vapor.

wmf_pressure_cooker_review_pressure_release

But that’s not all!

The cook can regulate how quickly to release pressure by the position of the release slide. Pull the slide forward just a tad and walk away to do something else and the cooker releases pressure slowly and delicately all by itself.  Pull it forward all the way to the end, and pressure will be released quickly (30-60 seconds, depending on the fill level).  The pressure release slider can be positioned anywhere in-between these positions for slow-medium, medium, and medium-fast releases.

wmf_pressure_cooker_review_handle_slide

Controlling the speed of pressure release is a major improvement from pressure cookers that release pressure with a trigger – which is basically an on/off switch. The only way to regulate the speed of a trigger release is by pulsing quick bursts of pressure – each burst violently boils the contents of the cooker – not very delicate.

Snap on! Click. Click. Snap off! Click. Click. Snap on, snap off.. the snapper!
The WMF Perfect Plus handle has one last trick.  It can removed quickly with the push of a button and easily snapped into place.  Unlike other cookers with removable handles, that need to be tightened before each use, this cooker’s handle hooks onto the lid and snaps into the right position on the first try and does not dislodge during use or storage.

wmf_pressure_cooker_review_removable_handle

A Tight Fit
The top and bottom halves of the long handle on the cooker are mounted very near each other in that the plastic of the top and bottom handle touch each other when twisted together.  On several occasions we’ve had difficulty opening this cooker and the accompanying pressure pan that came as part of a set. When the handles stick they really stick and need husband-strength twist to pull them apart and serve dinner.

wmf_pressure_cooker_review_tight_handles

WMF could not give us any more information about this problem because neither their customer service in the US nor the product management in Germany has heard of it. We could not ding their score due to the a problem only our model has experienced. However, if you have this cooker, please leave a comment below to let us know whether you have or have not experienced tightness in the handles.

There’s another kind of tight fit that does ding WMF’s score in this category. The cooking surface at the base of the cooker is only 7.6 inches wide (19.5 cm diameter) – this is the same width and surface area we didn’t like in the Fissler Vitavit and we still don’t like it WMF.

Clean-up: (5 out of 5 stars)

wmf_pressure_cooker_review_handle_cleaningThe WMF Perfect Plus is dishwasher safe! It gets a perfect score from us in this category. It’s so easy to dismantle, clean up and put this cooker back together we wonder why no one else is doing it.

  • Entire handle and valve mechanism is removed with the push of a button
  • Lid and base are dishwasher safe
  • Valve and gasket hand-wash only

The handle only needs to be run under hot water for clean-up- even after a particularly messy meal a quick rinse is all that was needed.

Accessories:

accessory_basketSold separately are a trivet and steamer basket (which we have not seen). And a glass lid that came with the pressure cooker set we received.

The glass lid is fantastic. It’s heavy -which is what you want in a lid- and the glass is so thick it could probably stop a bullet.  Our average run-of-the-mill glass lid weighs 14.5 ounces (416 g) while the WMF glass lid weighs 22.8 ounces (649g)! The handle is also mounted tightly onto the glass so when its run through the dish-washer liquid doesn’t pool between the two.

We don’t score for this but it’s worth noting that the instruction manual is not very good.

Although the manual for the American WMF’s contains twelve Lorna Sass recipes it’s devoid of any technical information about the cooker.  All of the specifications on the cooker’s pressure at high and low pressure were removed. We had to refer to the UK version of the user manual – for this information.

Both British and American manuals have one short paragraph each on canning, juicing and sterilizing but no practical or detailed information on how to actually do those things with the cooker. They also fail to list the features  and, more importantly,  detail the safety mechanisms – we had to email the manufacturer to get this information.

Other Details:

  • 18/10 Stainless Steel with 4.5mm aluminum disk in sandwich base
  • Available Sizes: 8.5, 6.5, 4 and 3 liters (manufacturer has rounded these European sizes down to quarts so if you purchase a 6.5 “quart” pressure cooker it is actually 6.86 quarts )
  • Spring Valve with indicator Bar (0 to 21.7 PSI)
  • Maximum Cooking Temperature measured at high pressure: 118.7°C (246°F)
  • Universal Base – safe to use on gas, electric, ceramic and induction cook-tops
  • Width: (opening) 8 1/2″ or 21.5 cm, cylindrical/conical; Height (internal) 7 3/4″ or 19.5 cm; Weight:  (Base) 5lbs or 2,256 k , (Base and Top) 7 1/3 lbs or 3,340k
  • 3 Year Manufacturer’s Warranty (excluding wearing parts)
  • Made in Germany
  • WMF  Perfect Plus Pressure Cooker Manual (UK version)
  • Manufacturer Website: WMF USA, WMF Germany
  • Recipes on this website using WMF Perfect Plus

Conclusion and Score:

We started this review with by busting the myth of the WMF Perfect Plus is “13 psi cooker” – it should be more accurately called “14 psi cooker” making it nearly as powerful as its European peers (which only reach 14.5 psi).

When our readers are shopping for cookers, or meet Laura Pazzaglia at a cooking demo, the question we receive most frequently is if premium cookers are worth the price. The answer is always the same: All pressure cookers pressure cook. With pressure cookers,  you really do get what you pay for. The higher the price, the easier they are to use and heftier the materials.  Premium cookers offer special little features that you didn’t think you ever needed (but can’t live without once they’re experienced).

The WMF Perfect Plus offers an auditory over-pressure alert, in-handle pressure release, and easy snap on/snap off handle (cleaning this cooker is literally a snap).

Tight handles, small cooking surface and forcing the cook to remember to lock the lid  (while so many other cookers are self-locking) are things we hope WMF will address in future models.

  1. I have this (WMF) pressure cooker and love it. I use the 4.5 liter one since I’m only cooking for 2 and use mostly Japanese pressure cooker recipes. The PC cookbooks here in Japan are mostly written for 4.5 liter ones. The only issues I’ve had with it is in one year of use the helper handle on the side has a small crack in the bottom but so fare isn’t affecting the use. The other issue is sometimes the pressure will be completely released (the little ball has dropped) but I still can’t open the lid. I found that the pressure indicator doesn’t descend all the way sometimes and when that happens I have to push on it with my finger while unlocking the handle, works every time. Sometimes it is a bit hard to twist open the lid, it’s like opening a sticky jam jar when that happens. The cookbook that came with it wasn’t thrilling, meat, meat, and more meat plus some rice. The manual wasn’t very helpful either. The other Japanese PC cookbooks I bought were better at explaining how to use PCs.

    1. Melanie, thanks for sharing your experience with the WMF – interesting to hear you’ve had the same problem with the handles that I had with my model.

      As for the cracked helper handle, check the last page of your manual to see the length of your warranty (for US & Europe its three years). It’s worth a shot to contact them just in case its a known manufacturing defect and then they could send you a replacement.

      When I got started pressure cooking, in Italy, the variety in recipes was only choosing between potatoes, beans and roasts – so I feel your pain. Let me know if there is a dish that you’d like to pressure cook in the Conversions forum and I’ll translate it to the pressure cooker for you – it might even make it to be a step-by-step photographed recipe.

      Ciao,

  2. My WMF Perfect Plus suffers the sticky lid release issue too. As noted above, I believe this typically happens when I don’t get the pressure handle cleaned really well when I’m in a hurry and it is blocked from opening. When I tap on the handle, I can hear something fall in the handle and presto, the lid safety mechanism releases and I can open it up.

    1. Thanks for stopping by, sidpost! I will tap the handle to “hear” what happens when I next use the WMF.

      I noticed that, sometimes, when they stick there is a little puddle of condensation in the little dip in the handle, and now wonder if that doesn’t just cause them to suction together.

      Ciao,

  3. In the Cook’s Illustrated review, they rated this PC as unsatisfactory, which seemed completely at odds with both your review as well as most Amazon reviewers. From what I have read, WMF PC’s were downgraded due to their tall, narrow shape. What is your opinion on that? My status is: I don’t have a PC, my only memory of a PC is of watching my Mother use a PC when I was a kid, and being scared of it. Now, at this advanced age (58!) I have decided that I can’t live another month without a PC. With cost not an issue for me, what would you recommend? .

    1. Frankly, I read the reviews and saw several pressure cookers that I highly value dinged for some problems I have never personally experienced (such as food scorching around the bulging base of the Fagor, or the Magefesa not maintaining pressure). As an expert I can read through the lines and determine that most of those comments are based on user error: Using a flame that is too high and wide for the base (on a commercial cook top) and not reading the instructions to determine how to tell when a cooker has reached pressure and when its OK to turn down the heat. This will all sound like greek to you, now but once you start pressure cooking the above paragrph will make sense!

      I make lunch, dinner in the pressure cooker every day – and dessert and conserves on occasion. I don’t cook in a test kitchen, though I do test my recipes several times, I cook for my family.

      Though it is true that high sides are awkward to use when browning meats the benefits, in my opinion outweigh getting used to using long tongs to flip something around at the base of the cooker.

      For example, a tall cooker allows you to make one-pot meals like curry and rice:
      http://www.hippressurecooking.com/pressure-cooked-chickpea-curry-with-brown-rice-one-pot-meal/

      Or pressure cook three beans at once:
      http://www.hippressurecooking.com/american-three-bean-salad-pressure-cooked-together/

      If cost is not an issue – go for the WMF set. It comes with one high-sided 6.5L and one low-sided 3L pressure pan and the best part is that you can use the base most suited to the recipe you plan to pressure cook!

      Here are my basic pressure cooker recommendations:
      http://www.hippressurecooking.com/go-shopping/

    2. Tall narrow shape?

      Not as narrow as my largest Kuhn Rikon. These pressure cookers fit my stove well so, I don’t understand why I would want one shorter and fatter.

  4. I purchased this product. However it didn’t work after I used once. The worst thing was not the malfunction of this product but the maintenance and the service of WMF america. I’ve waited for their response about 6 month and got the product back after 3 month more. Their maintenance and service was very very very bad. This experience made me not to buy any products of WMF.

    1. Dear readers, I want to note that after receiving the above comment I contacted WMF immediately to let them know. They wanted to get in touch with this commenter privately to know more about what happened but when I asked the commenter for permission to share their contact information they preferred I do not. So, I did not.

      WMF is aware of both this comment and the negative comment placed on the amazon.com review page which – according to the location information I am privy to – do not appear to come from the same person.

      I certainly hope that these are isolated incidences and that WMF will respond publicly to clarify this situation – though without more information about the commenter they will likely not be able to shed any light on the specific experience referenced above.

      In the interest of fairness, openness and debate it is our policy to publish both positive and negative comments and to protect the privacy of our readers.

  5. I just bought one of these pressure cookers, so I’ll add some initial thoughts/questions:

    So far I have been happy with it. It appears to take longer to come to pressure than my Kuhn Rikon, but I have not yet done a far comparison. Any one else feel the same way?

    Also, the secondary safety valve puts out **WAY MORE** steam than I was expecting prior to pressure being established. Might be my design but I would like to hear from others.

    I have not had the handle issue.

    Lastly, I have the sticky lid issue as well, but I do not think it is as bad as it has been for others.

  6. Laura, you’ve got me quite interested in the WMF line.

    I can’t send you a direction link because it’s a flash brochure. but….

    On page 88 / 89 of this brochure (see screen cap) I noticed that the Perfect Plus is just one of 4 models WMF does… Do you suppose the two listed ahead of it, the Ultra and Pro, are meant by WMF anyway to be slightly more expensive models? I see the Ultra has an actual timer in the handle.

  7. I purchased the larger version thinning it would be useful for cooking larger items. It takes up a lot of space obvious really but wished I had the slitly smaller one.
    I initially purchased an inexpensive prestige verisimilitude to see if PC worked for me then decided to trade up and what a difference in noise and steam.
    I have experienced the PC being difficult to open but have found that flicking the open/close button was sufficient to release.
    So loving learning how to use it more fully just wish it wasn’t so big.

  8. English Rose….

    you wrote, “what a difference in noise and steam…”

    Do you mean the Prestige made more noise and steam, or the WMF did?

  9. The prestige was much noisier and gave off steam throughout the cooking process. The WMF obviously gives off steam when using fast release but the only time it is noisy is if the pressure gets too high it sort of toots.
    However the prestige was a third of the price of the WMF!

  10. Okay thanks English Rose, good to know that WMF is worth the extra money in that regard too at least.

    The old saying used to be, “you only get what you pay for.” Nowadays, it seems that even paying a lot isn’t a guarantee anymore either of getting quality, so it’s good to know when you do get a lil extra quality for your hard-earned money.

  11. I bought my first and only WMF Perfect 6.5 liter in Germany 25 years ago. It is still like new. I never had to get spare parts. Pressure cooking is the way to go.
    Greetings from California
    Ps. I use it every day

    1. WOW! Thanks for sharing this – what a testament to the durability of their cookers!

      Ciao,

  12. I have had a WMF Perfect set (4.5 liter + 2.5 liter) for a bit longer than 14 years now. I use either one practically every day. During this time I have changed the wearable parts (rubber ring and the silicone valve) a few times as usual, since those pieces get hard with time and use and loose the needed elasticity. Both cookers are still 100%, including handles and lid.

    Now I am getting a new kitchen and have to exchange them. At the time when I bought my cookers, they were not made to be used on induction cooking tops… :-( I am certainly going to get the same set again.

    Regarding WMF customer service, they have been excellent in my experience. I own a set of WMF regular pots and, after 10 years of use, one of the lids released its handle. I contacted their customer service to ask them which other lid would fit my pot, since that series had been discontinued. A few days later I found in my mailbox a little package with a replacement lid and a nice letter excusing for the material failure.

    Greetings from Heidelberg, Germany.

  13. Bought the 6.5 litre as a Christmas present for myself after reading the reviews! Just fab, my older prestige would not get to pressure and hence burnt on the bottom. The wmf is perfect! So much so, decided that I needed a couple more! So bought the 4.5 & 3 ltr. Set as well. I did feel guilty as they are not cheap, but this set covers all our needs. The 6ltr one is used for stews etc. and when we are cooking for the grown up children on visits, also for beans. The 4.5 good for ragus and pastas for when we cook for more than just us two. The 3ltr now gets the most use. It is perfect for my favourites like spinach pasta for 2-4 persons (had that last night)! And the risotto, would have that every night if I could get away with it! As for the sticky handle issue, last night was the first time it happened. So I tapped the cooker on the hob, then slid the release back and forward a couple of times. It then opened ok, a bit stiff but I still managed it and I have arthritis so most should be able to do it. Secondly, customer service, got mine from amazon uk, the secon set handle didn’t toot when over pressure, so I contacted amazon for new hande, they sent a new cooker next day delivery and then I returned the other ones. What service! So I am very, very pleased all round! Laura, keep up the good irk, most appreciated.

    1. LMC food, glad to read that you’re so pleased with your WMF’s. You’ve got the PERFECT set-up: I recommend serious cooks moving almost all of their cooking to the pressure cooker to have three pressure cookers!

      Ciao,

  14. I am considering a PC for a Christmas present. I have and love my kuhn Rikons, but am thinking the 4.5+3 WMF set would be good for the planned recipient. The sticky handle issue that has been a recurring theme in this thread is a concern though. Has there been a final resolution to this issue?

  15. hi
    bought WMF large one and so pleased bought the 4&3 set. absolutely impressed. as for sticky handle, I have bad shoulder and elbow joints and other stuff!!! never found it a problem, so go for it, they will be delighted and you might want to trade in you KR! lol

  16. I love this WMF…way better than Kuhn Rikon in its usability, design and materials and have been very impressed by it since 3 years ago. If anyone is interested in buying, keep in mind there’s a combo deal on Amazon for 8.5QT and 4.5QT or 6.5QT and 3 QT that basically sells for the price of one. I got the 8.5 and 4.5 combo myself because I use the big one for making stocks and the small one to make meals…perfect size and very good value for money.

  17. Thinking more about this… you know the handles don’t look overly comfortable to use without the pressure lid, because of the sticky up thing in the middle of them (see attached picture to see what I’m thinking of)… and I’m often using two pressure cookers at the exact same time, I’m not seeing the pressure of getting a second pressure lid on Amazon so you can use both pots at once…? Cause I almost certainly would need to.

  18. Er, above should say, “… I’m not seeing the *price* of getting….”

  19. Thank you for this review (and the commenters for their useful input). I had been trying to decide which pressure cooker to get, and when I found a good deal on a Perfect Plus set, I trusted the good reports and invested in them. I have the 8.5 and 4.5 quart set and couldn’t be happier. They are so easy to use and clean (no sticky handles for me), and I can’t believe I have gone all these years without a pressure cooker. I was initially confused by which ring was the 1st or 2nd because there are 3, but a close reading of the manual made it clear that the first yellow ring just indicates that the pot is under pressure and the low and high pressure settings correspond to the two red rings. I saw an online video where someone got this wrong, so I clearly wasn’t the only one confused at the outset. The only real challenge I have had with these pots is figuring how how to make room for them in my kitchen, but as long as I am using them nearly every day, I figure putting them away is a low priority. By the way, I love the sizes in this set. The 8.5 quart gives me plenty of wiggle room, so I can make a big bunch of stock or just not worry about reaching fill limits for most cooking, and if I know I really don’t need a lot of space, the 4.5 quart still holds a lot while being kind of the sports car model (fast to come to pressure and easy to move around). I’m spreading the word about modern pressure cookers, in part because my experience with the Perfect Plus has been so positive. Never again will I get home late with the kids and not have time to make dinner. Thanks again for your website and reviews.

  20. Hi Laura,

    Firstly, Thanks a ton for the wealth of information on pressure cookers and pressure cooking both. I was keen to buy a premium PC but couldn’t arrive at a decision. There are so many to pick from.

    I am very happy with your review of the WMF PC and decided to go ahead and buy one from Germany, although I live in Sydney. But I am a little confused with the various models on their website. I do not understand the differences between the WMF Perfect and WMF Perfect Plus models. I called their customer service up in Germany but they just transferred my calls between each other and then hung up. Perhaps they are not keen to speak in English.
    Could you kindly let me know what the differences might be between WMF Perfect and Perfect Plus ?
    Also, could you share on what occasions you find the 8.5 ltr ones useful, as I am planning to buy a 6.5 ltr one.

    Thanks,
    Ben

    1. Just to confuse matters they also have the Perfect Ultra and the Perfect Pro – personally I only have direct experience with the Perfect Plus so I can only look at the online instruction manual of the plus and tell you that it “appears” to be very similar if not the same construction. This is just the outward appearance as their pressure mechanism is completely enclosed with an outer bakelite structure. It appears that the shape of this container is different but I cannot confirm if what is inside is different.

      Recently, in the WMF forum, a reader reported that WMF told them that the build of the WMF valve has changed so that if you push this huge piece that looks like a button waiting to be pushed the valve is not damaged. So, I’m going to say that the main difference is that the Plus is the newer model (and possibly construction) without any additional features.

      As far as the size goes, I recommend you read my pressure cooker capacity article to determine which size is right for you. You can roughly calculate 1L/qt per person when choosing a pressure cooker – so a 6L stockpot-type (which is my recommended starter size) can feed from 0-6 people, while the 8L can feed 0-8 people. If you never cook for such a loud crowd regularly then it’s better to start with the 6L.

      See also my is “Does pressure cooker size matter?” article for details as to why you should get the smallest cooker for your cooking needs.

    2. I assume that in 2017 you have already purchased but this is just in case anyone else is interested. I have had a WMF Perfect PC set one medium- large base (I think about 6 litres, there is a larger one available which I think is the 8 litre one) and one small size (2.5 litre I think) which I have had for about 12 years. They came in a set from a famous Spanish department store along with a trivet and basket (the smallish one, there is a larger basket available here in Spain ). I can’t remember it coming with a glass lid too and just one PC lid for the two bases. Can’t say that I have ever needed a second lid.
      This was on offer at the time of purchase and very good value but still expensive – my Irish mother got it for me.It was recommended to me by several work colleagues and is super quick to come to pressure on my induction hob in the extra power mode:about 3-4 minutes to get to the second red ring when the large pot is 3/4 full. Here in Spain the Perfect Plus was also being sold at the time but the saleswoman said that the system was the same (the Perfect Plus handles are more rounded so more attractive? But also quite a bit more in terms of price)
      Anyway I am glad my mum got them for me: the clean up really is excellent- stainless steel is the way to go. I probably wouldn’t have brought them for myself as we had 3 young children and a new mortgage to pay for!!!
      The two models are still being sold, along with a more sofisticated looking one with a timer in the handle which the sales people didn’t think was worth the money (you can use the timer on your induction hob or the minute minder on your oven?).It doesn’t seem to have been so successful here at least.
      There is also a great range of spare parts/ accessories eg the large basket , trivets , seals replacement handles etc etc sold in El Corte Inglés and smaller service centres: never any problem to get a replacement seal but not cheap (10,50 €) .Think in this case you get what you pay for-well built, designed and long lasting and much much quicker than my mum’s old Prestige aluminium weighted PC which she always used to cook bacon (gammon ) and cabbage in!!!
      Fagor and Magfesa are two Spanish makes (pressure cookers are popular to speed up traditional Spanish cookery) and much cheaper here and although the design has improved over the last few years I think that you get what you pay for here….I would make the investment if you can.
      It’s mainly used for chickpea or lentil stew although have done stock, rice pudding etc.
      The handles DO sometimes stick but the tips the others have posted usually sort it out. That or my husband!!!

  21. I have a whole range of WMF products, pans, cookers, pots and even knifes and peeler…
    This is more because of my husband.
    I too liked their products until I had a bad service experience.

    Seems like Germany employs only people with special qualification to be rude in not only their selling branches but also at their customer support.

    I have myself worked as a design engineer in a home products company, specializing with cooker hood designing. Now I work as an engineer customer support for a big bio-medical company. We are rated based on our conversation and the service we offer to our customer. With a brand name like the one for WMF, I expected better.

    I purchased a cooker from WMY in I noticed a fine crack on the handle of my cooker in August 2013. Since we had decided to move into our new house I wanted to inaugurate the cooker in the new house. So, although I had bought a cooker, I started to use it only from March 2014. I had regular issues with the cooker. The safety valve with pressure bild up and would open up to release the pressure. This would thoroughly mess up my kitchen. (I have pictures of this). This had never happened in my 15 years of cooking experience. Also, me being an Indian I have grown up with cooker cooking ;)!!!

    In March this year I noticed that there was a fine crack in the cooker lid handle. Initially I thought it was a design. But the crack seemed to grow longer. So I took it to the store to get an opinion. The lady at the store treated me like a pain in the wrong place but told me that it was a defect and not a design. She told me that she had to send it to her manufacturing unit to get it tested, to check if it was a manufacturing defect or user defect. Fair enough!! I only explained to her that user defect could not produce a fine crack in a place like this (I have pictures). My request was that I get a quick response because I needed my cooker for everyday cooking..

    After 3 weeks I got a call back and was informed that it was indeed a part defect and that I could go and collect the spare part. I went to the store happy to have my cooker back in shape. When I went to the store to collect my part, I was told that I had to buy it. Since this was unclear to me, I asked them for a reason. Reason was unclear. Not mentioned to me… When I asked her why I was informed that I could collect the spare part, she was not sure who had spoken to me. Buying the part was not my problem. I was upset with the principle behind customer support….

    I decided to contact the customer support. The lady on phone informed me that a gummy part inside the handle was defective and that since gummy parts have no guaranty I had to buy the part. I was obviously upset that a part somewhere inside and not reachable to the customer is defective and I had to pay for the damage. When I asked her to explain the logic, she was pretty rude and did not bother to explain things to me. When like an upset customer I complained about WMF service, her reaction was lit that of “I don’t F—— care!!”
    Besides, they have now damaged my lid handle and I have no choice but to buy another handle..

    I will now seriously consider either buying or advertising WMF products!!!
    Give it a thought before you buy WMF as well because their service SUCKS BIG TIME!!!

  22. I bought the WMF pressure cooker set Perfect Plus 3L and 6L in 2012. Throughout the last 3 years, there are weeks where I use the pressure cooker 3-4 times per week and other times I alternate my cooking with the slow cooker. I find certain foods are better cooked in pressure cooker and others benefit more from slow cooking.

    I am satisfied with product but disapointed with the fact it does not hum when it reaches over pressure, my pressure cooker makes instead hissing sound. Usually while pressure is building up, I quickly pick up the mess I made in the chopping board and start washing the utensils I used to prepare ingrédients (bowls, measuring cup, measuring spoons, knifes, etc). Of course I keep checking every once in a while if sealing indicator is rising but I also have my kids playing in the background or asking me for my help. My kids know, they can’t cross an imaginary line in the kitchen while I’m cooking because an accident can quickly happen. If the humming sound would work as in their video, it would help me for those times I have my back turned for longer than expected. My kitchen sink is right accross my stove and fridge, as I have said I just have my back turned to put away spices, wash pots and pick up counter. I now use my stove timer to ring to an approximate x minutes, so I could turn and check if cooking indicator has gone up to 1st or 2nd orange ring according to food I,m making. Once it reaches the desired ring, I set the timer.

    It does not bother me to adjust the cooking times to 1 or 2 minutes more than the suggested times of the chart for pressure cooking. Its much faster than cooking the traditional way.

    One of the reasons I bought it was for the indentation filling lines capacity. The 1/3 line is useful when you need to calculate the amount to pour of liquid (water or broth) to mix with your ingrédients. When I cook with the 3L PC and I need 1L of liquid for my soups, this line makes it easy by not measuring the liquid in a measuring glass.

    I also experienced the same problem operning, the lid handle gets stuck. I also noticed there is condensation that builts up between the lid handle and the long base handle which is what makes it hard to open. To open I shake the pot in the air, which usually releases more pressure and this helps me open the lid. Sometimes, the yellow ring of the sealing indicator is slightly elevated and does not go down completely as if it was stuck. Once again I shake the pot and it helps release more pressure. Other times, I use the quick realease method with pouring water on top of lid and making sure not to pour water on the valve.

    My mother bought herself this past August 2015 the 4L WMF pressure cooker Perfect Plus. Hers makes the humming sound when it reaches over pressure unlike mine. She also got the same problem of condensation built up between the lid handle and the long base handle of the pressure cooker. She does the same thing, shakes pot and taps before sliding the lid handle to open PC. So far she likes the experience cooking with this pressure cooker, and sees the difference between an old aluminium pressure cooker she had in the early 80s.

    I love steaming vegetables in the pressure cooker, I found it has more flavour and cuts cooking time.

    I also think the reason the pots diameter are smaller than the ones in North America is because I’ve noticed the Europeans tend to have smaller household electrical appliances.

    I’m happy overall with my experience cooking with pressure cooker.

  23. Hi. I have the 6.5 and the handle got a crack where it snaps in. I am very careful with handling and cleaning so am not sure how this happened. It was within the warranty period but they did not cover it. A new piece was almost $100. After I pitched a royal fit as this was not a cheap purchase they took $50 off the replacement handle. Left kind of a bad taste in my mouth. Other than that I love it. I have also experienced the sticking and if I push down on the disks can open. Seems like a small bit of pressure is retained.

    1. The more I read comments from WMF owners the more I ask myself how WMF could NOT know about the handles sticking!

      Interesting, too, to hear that they would not cover a crack in the warranty period and make you pay for a replacement.

      Thanks for sharing your experience!

  24. I have had the 4.5 litre version for about ten years and I use it a lot. I love it, it’s so much better than the old Prestige ones where you had to change the weights and the weights hissed and bounced up and down. My Mum’s used to terrify me.

    I really like that it is stainless steel rather than aluminium. When I bought mine it was the only stainless steel one I could find.

    It took a few years before I realised that the lid was hard top open sometimes because the locking mechanism hadn’t released correctly. All you need to do is tap the big button that goes up and down and has the rings, then it opens really easily.

    I’ve had no other problems at all.

  25. I bought a set of 4.5l and 3l Wmf Perfect Plus pressure cooker few months ago. I have recently had one trouble with the handle. Steam or water is escaping from the handle (see picture) during cooking so sometimes my food is burned out. Please let me know what happens with my cooker?

    1. Binh, remove the handle completely and clean the lid and and handle well especially around the silicone stubbies- it looks like from the lid some starch has sprayed out of the valve and it has left a patina on the lid and is likely affecting the operation of the handle. When pressure cooking rice, make sure to always use the Natural Release setting.

      If it doesn’t work, join us in the forums with the following information (and test results)….
