Because the TM6 measuring cup sits snugly in the mixing bowl lid, it is possible, in isolated cases, for the cooked food to suddenly escape during cooking.
When cooking at temperatures of 95°C (200°F) or above: to prevent the opening in the lid from becoming sealed by the measuring cup, which fits tightly in the opening, use the simmering basket or Varoma dish, which only sit loosely on top. Only insert the measuring cup if the simmering basket is already being used in the mixing bowl.

How do I know if I have a Thermomix® TM5 or Thermomix® TM6 measuring cup?

You can differentiate the two measuring cups by the fit into zje lid hole. The original TM5 measuring cup sits loosely in the mixing bowl lid and is mostly transparent. The color amd material of the TM5 measuring cup may vary depending on the production date.
The original TM6 measuring cup is dark grey, never transparent, it sits tightly in the mixing bowl lid.
So please check which measuring cup model you are using. The situation does not arise if a TM5 measuring cup is used. Users of a Thermomix® TM5 should check whether they are using a TM6 measuring cup. If a TM6 measuring cup, which fits tightly in the lid, is being used, this information will also apply to predecessor models.

Do we exchange the Thermomix® TM6 measuring cup with a new model or the Thermomix® TM5 measuring cup?

No, a switch from a Thermomix® TM6 measuring cup to a TM5 one is not needed at all. The issue is solved when using the simmering basket with recipes that require a temperature of 95°C (200°F) or above. This is a simple but necessary measure that will hardly affect the cooking experience – but can prevent this potential problem from occurring.

Will this action (replacement of simmering basket) affect the taste of the recipes and how do you ensure sucess guarantee after this change?

This is a simple but necessary measure that will hardly affect the cooking experience – but can prevent this potential problem from occurring. Of course, our commitment is to offer the best recipes with our Thermomix® success guarantee and we will make sure of that by sticking to our thorough testing phases. In case of facing challenges with cooking results, please refer to your local customer care.
Maintaining the highest safety standards for our Thermomix® customers is a top priority at Vorwerk. Therefore, the strict policy is to react proactively and with foresight, in order to avoid possible adverse effects for our customers.

Are the affected recipes adjusted with instructions on which item to use, e.g., simmering basket, Varoma®, measuring cup?

As part of the continuous development of the Thermomix®, we have already adapted the recipes available in Guided Cooking to reflect this, so that our Thermomix® customers are actively and visibly informed of its correct use. What’s more, the software for the Thermomix® TM6 has been modified so that the user is also instructed to use the simmering basket instead of the measuring cup when cooking without the use of the Guided Cooking function (manual cooking).

What measures do I have to take and which attachment must be used for which foods (measuring cup, Varoma®, simmering basket)?

The most important step is to download and install the latest Thermomix® software update that is being delivered to all Thermomix® TM5 and TM6. At least version 2.13 for TM5 and version 3.5 for TM6. It is readily available on your device when connected to WiFi. The TM6 software contents additional safety instructions when cooking without the use of the Guided Cooking function as well.
For cooking (simmering) at temperatures of 95°C or above (200°F), the simmering basket should always be used instead of the TM6 measuring cup, as the TM6 measuring cup fits tightly in the lid. The simmering basket rests loosely on top, is steam-permeable, and also prevents food spatter from the mixing bowl. This is a simple but necessary measure that will hardly affect the cooking experience – but can prevent this potential problem from occurring.
Soups, casseroles and jams must always be cooked at a temperature no higher than 100°C (212°F). For recipes that require a higher temperature, the Varoma® is to be used, as designated in the recipe.
Furthermore, the (known) maximum fill level for the mixing bowl (2.2L for the Thermomix® TM6 and Thermomix® TM5) must always be adhered to.

I have a Thermomix® TM6/TM5/TM31 - is my device also affected?

It depends on which measuring cup is used. So please check which measuring cup you are using at the moment. When the Thermomix® TM6 measuring cup is inserted in the Thermomix TM6, it fits tightly in the lid. The fact that it is firmly lodged prevents it from falling out when the mixing bowl lid is removed. The measuring cup on the TM6 is designed so that sufficient steam from the mixing bowl can escape at the edges when cooking or simmering. However, during the cooking process or when following certain recipes, ingredients can float to the top, become compressed and prevent steam from escaping. Consequently, in extremely rare cases, increased pressure can build up in the mixing bowl during cooking or simmering (or heating at temperatures of 95°C / 200°F and above), which can lead to a sudden and uncontrolled spillage of hot food, which in single cases can cause burns. This situation does not arise if a TM5 measuring cup is used, as the measuring cup for the TM5 sits loosely in the lid of the mixing bowl. Users of a predecessor model should check whether they are using a TM6 measuring cup. If a TM6 measuring cup, which fits tightly in the lid, is being used, the information will also apply to predecessor models. It should be noted in any case that the likelihood of hot food overflowing or erupting is considerably higher if the fill level recommended in the manual and also indicated on the inside of the mixing bowl is exceeded.

I am cooking with my recipe chips. Are these recipes being adapted?

If you are a Thermomix® TM5 customer, please check: which measuring cup model you are using. This situation does not arise if a TM5 measuring cup is used, as the measuring cup for the TM5 sits loosely in the lid of the mixing bowl. Users of a predecessor model should check whether they are using a TM6 measuring cup. If a TM6 measuring cup, which fits tightly in the lid, is being used, this information will also apply to predecessor models. If you are a Thermomix® TM5 customer and only cook with the recipe chips, the recipes on the recipe chips cannot be changed. Therefore, you will not see any changes when you cook from there as this is a closed system. If you have a Cook-Key® then you will be able to see the recipes that are on your recipe chips also on Cookidoo®. And on Cookidoo® we will provide an update on all these recipes. So you will be able to synch those updated recipes with your Thermomix® TM5.

How to use the appliance when the simmering basket is inside according to the recipe (e.g. when boiling rice)? Should we keep the measuring cup?

Certain recipes call for the simmering basket to be used in the mixing bowl. For these recipes, the measuring cup can still be used.

Is there a special recommendation for Thermomix® TM5 customers?

This situation does not arise if a TM5 measuring cup is used, as the measuring cup for the TM5 sits loosely in the lid of the mixing bowl. Users of a predecessor model should check whether they are using a Thermomix® TM6 measuring cup. If a TM6 measuring cup, which fits tightly in the lid, is being used, these new guidelines will also apply to predecessor models: For cooking (simmering) at temperatures of 95°C or above (200°F), the simmering basket should always be used instead of the TM6 measuring cup
