  • Hello.
    I would like to inform current and future buyers of the thermomix TM6 device about the possibility of the mixing knife wearing out too quickly (for me), which results in leaks from the bottom of the mixing bowl. During the sale, the employee did not mention anything about the knife wearing out. Of course, he mentioned that if the knife gets dull, it can be sharpened by crushing ice in the device. The user manual provides a table that informs when it is recommended to replace the mixing knife.
    Termomix TM6 - worn mixing knife, causing leakage from the mixing bowl.
    Several friends have different versions of the device and the earliest they had to replace the knife was after 6-7 years. Everything is fine, but our device is 2.5 years old, so it is just out of warranty. We crushed the ice maybe 10 times, and ground the grains a few times to test it. Generally, we cook soups and make cakes in it. I don`t think it`s "hard work" for the device. My sister-in-law has the same problem, except that the device is 1.5 years old, so it is still under warranty. In my opinion, this is an obvious mistake by the manufacturer of the device that cost a lot of money. It smells "Chinese" to me here.
    At first I suspected the seal between the knife and the bowl of the device.

    I contacted the service. The employee claims that since the new version of the device entered the market, there has been no case of the above-mentioned seal breaking down, and the knives have as well. How to recognize a used knife? After that...

    Someone will say that it is just a slight leak, and there is a drain in the device. Yes, yes, but over time the leak becomes larger (these are photos from the beginning, when I still thought that my wife had something leaking on the outside of the vessel), it fills the "star" and floods the inputs of the power pins, and in such a situation it is a simple step to a short circuit and serious failure.
    There was nothing left for me to do but buy a new knife, which I did. The cost is considerable - PLN 254 (I got it on Black Friday for PLN 204). After installing the new part, there was no leakage. There is no play on the knife axis - the old one could be moved sideways to a small but noticeable extent. The bearing seal is probably worn out.
    I`m not saying that the device is bad because my wife is very satisfied, but the quality of the knife for such use is insufficient for me. Buyers should add the cost of a new knife (it comes with a seal included) to the operating costs.
    Regards

    Thanks for sharing the information, because you are right, the cost of the device is not small. I wonder what it looks like in the lidlomix design? Although, due to the price, the knives can be replaced every year ;) Another thing is that these knives are actually the most important part of the structure and they are responsible for many things - dishes ;)

    And by any chance, thermomix doesn`t have a lifetime warranty? Or some mega-long one (like 40 years?)? I don`t have one myself, but a friend of mine has several different versions (in several homes) and she said something like this - you send it back and you probably get the current version?

    No, there isn`t. The standard is 24 months, but this can be considered a consumable part, so a shorter warranty would be available.

    It probably never had a lifetime warranty. I have had the TM 21 model in my house since 1995. But the first replacement of knives occurred after about 15 years. Those models were produced by the Germans. My wife still works on this TM 21.

    As for Lidlomix... a friend had one and a gear or something failed. The family lives in Germany and they visited the manufacturer itself... Unfortunately, the part is unavailable, so the device had to be thrown away and the bad taste remained. Fortunately, I haven`t heard of many such cases. It could have been a material defect, which is bad luck :)

    Sometimes my wife washes it in the dishwasher, but the instructions say it can be washed, so it shouldn`t affect it.

    We have come to times where "Made in Germany" does not guarantee good workmanship. And once, a "Made in DDR" food processor worked for over 10 years despite several falls from the table. Since accountants stood in the way of engineers, quality has fallen by the wayside.

    Be happy that it worked at least that much. When my wife retired 4 years ago, she received a full set of a food processor from her co-workers. I will not consciously mention the company or type. The robot was great, the company was very well-known, but when it comes to the shredding attachment, there was a gap of over 2 cm between the channel and the disc/shredder. There were no strainers, filters, etc., included in the set. The website stated that this model "is like that" and that is why it was discounted. GOOD NIGHT LADY....

    I had a HOFFEN CE-2000 S robot repaired. Here, the "upper" bearings in the knife and the "lower" gear bearings looked like this:

    I replaced the bearings, oil seals and segers with new ones with increased operating temperature. It cost me 1/3 of the price of a new knife for this model.

    I will refer to the information from the first post that crushing ice sharpens the knife. Well, no, because crushing the ice causes its wear and this is probably clear from the information about the frequency of its replacement (the more often you crush the ice, the more often you change the knife)

    This ice trick is a marketing gimmick by sellers.

    In Lidlomix (SILVERCREST Monsieur Cuisine PLUS), when the knife axis is stuck, the clutch is damaged.

    You`re right, it got dull very quickly. We use old thermomixes and they are almost 20 years old. We replaced the knives twice. Cost about PLN 250 each. We bought 1 piece to stock from the last stock levels. The manufacturer does not have to provide access to spare parts 10 years after the end of production. This is actually important if someone has an older model, and as we know, they are long-lived - these older models.

    You are absolutely right, but firstly, my wife bought Termiś herself without my participation in the whole project (I did not add a single Polish onion, that is, zloty - and I`m sorry, I bought the mentioned knife), and secondly, a good seller praises and presents only the advantages of the device, hiding /hiding the disadvantages. Besides, I know maybe one woman who would go red if she heard about a knife being sharpened with ice.

    They invented these durak machines because "babies" stopped being able to cook. :not:
    Honestly, I would rather learn to cook myself if I couldn`t, or send a woman to Geslerowa, than invest in such a device.

    As for the price, just go back to when 20 years ago there were shows of "wonderful" stainless steel pots in our country and the exhibitors were as naive as they wanted, e.g. a set of pots for PLN 5-10,000, and today you can buy the same set for PLN 200.

    These demonstrations of wonderful pots are still there... As for this device, as you call it, it is also about saving time, for people who work and do not have the whole day to themselves it is a useful device. No, I don`t have it and I don`t advertise it, but my friends have it and praise it.

    But will you make dinner for the whole family or just two people and a dog? At home we have a traditional Kenwood Chef with a bowl that is three times more capacious than the TM6, and when it comes to cakes, it is just one bowl for 1 cake tin for the oven, the ingredients are poured to half the volume of the bowl..

    Thermomix is for people who would normally die of hunger or kill their loved ones with their products. The device guides you by the hand and you have to really try not to fail. Although I know one person who bought a thermomix, the food she cooks is still inedible and despite the seller`s attempts and many demonstrations, there is still nothing (this is due to the scatterbrain and chaos created by this person). As for washing the knife in the dishwasher, I advise against it. Unfortunately, it will always draw water drops from the dishwasher to the bearings, and salt and detergents will wreak havoc. Sharpening a knife with ice, a salesman`s story. Although it can be tightened normally. In my opinion, the device is worth about PLN 2,000.

    TM5 has built-in pressure sensors in its legs. This makes the entire device a scale. This is a very cool feature.
    There is a whole large series that has faulty sensors that simply break down.
    This is first manifested by "floating" of the scale readings. This means that the device stands still, we don`t move anything, and the scale keeps jumping -20g, 0g, +20g.
    Then the fault gets worse and the scale shows either 0 or MAX. Nothing in between.
    It may seem like nothing, but this glitch basically makes it impossible to cook according to the recipes. Because in their recipes, all ingredient amounts are given in grams. Even water and milk are in grams instead of milliliters.

    I don`t know what is causing the problem. Are these faulty sensors? Is there some design error that causes the transfer of too high forces and mechanical damage to the sensors?

    Probably strain gauges don`t really like the vibrations that occur when the engine is running.

    My wife cooked very well and still cooks without TM6 (although now more often with TM), I only wash it and if I cook it, I cook it "the old way". The advantage is, above all, the speed of doing certain things (chopping vegetables - uno secondo and yes, kneading dough for cakes/dumplings, etc.). With the varoma you can make an entire dinner in one go without using, for example, three pots. In general, people who use/have used it should comment on the effectiveness of Termomix, not dissatisfied people who have only seen it and heard something about it. I admit that I still consider the purchase of TM6 a waste of money (I see some advantages, but are they worth 5,000 Polish onions?), but my wife bought it and is happy, so... me and my stomach are too :D

    Comparison of the old and new knife.

    Old knife:
    Termomix TM6 - worn mixing knife, causing leakage from the mixing bowl.
    New knife:

    As you can see, there are no significant differences. There is a small chip on the old knife, you can feel the difference in sharpness under your finger, but there is no tragedy with the old blade. You can always sharpen them and use them for heavy work - peanut butter, etc., because it does not leak through in thick "dishes".

    Has anyone taken this knife apart before? I`m not handy with tools, but in this case I don`t really know where to start and I don`t want to ruin it right away because, as I wrote before, I might have to do some work with the nuts. Maybe in two years, when I buy another one, I`ll have this one autopsied :D

    A similar myth circulates about sharpening blades by mixing salt.
    I advise you to be careful when sharpening and not to collect a lot of material because the blades tend to be very shallowly hardened.

    I`m afraid that the knife axis is stuck on the face, as in most modern blenders, these are not the times when something unscrewed.

    This way the thread is pressed at the end. You would have to grind the end of the axle and then unscrew it. Then you can remove the knives, but underneath there is a metal cap pressed onto a plastic casing, and then there are the bearings with seals. Basically, they made sure it couldn`t be fixed.

    So... the probability of an autopsy is increasing, and if you buy new knives on Black Friday, at least PLN 50 will remain in your pocket, which can be spent on fruit for children and a medicinal kidney rinsing solution for daddy called beer. :D

    The axle end is secured against unscrewing. But I don`t remember whether it has a left or right thread. I made sections in TM5 and the knife there is identical.

    I have a Thermomix TM31, I bought it when my child was born and now he is 12 years old. During this period, I replaced the cover gasket once and the knife last year. I noticed that after removing the knife, a brown coating appeared on the seal. It was the same in the base. So I bought a new knife and it still works. The only thing I don`t like is the plastic, transparent cover from Waroma. It`s all cracked. Also one or two buttons have rubber.
    I think that 12 years without any major problems is not a bad result.

Topic summary

The discussion centers around the Thermomix TM6 and issues related to the mixing knife wearing out prematurely, leading to leaks from the mixing bowl. The original poster expresses concern about the knife's durability, noting that their device is only 2.5 years old and out of warranty, while friends with older models have not faced similar issues for 6-7 years. Participants discuss warranty limitations, with the standard being 24 months, and share experiences with older models like TM21 and TM31, which reportedly had longer-lasting knives. There is skepticism about the effectiveness of the ice-crushing method for sharpening the knife, with some asserting it may actually contribute to wear. The conversation also touches on the perceived decline in product quality over time and the challenges of obtaining spare parts for older models.
