Thermomix® leaking: liquid under the bowl
It’s wet under the bowl or dripping from the knife? Safety first, then the cause: here’s what to do.
In short
If there is liquid inside the machine, unplug it immediately and don’t switch it on again. A few drops from washing up or from condensation are harmless. If it keeps getting wet, the knife, seal or bowl isn’t fitted properly or is worn.
Act now: unplug, don’t tip the machine, don’t hold it under water and don’t switch it on again until it has been checked. Liquid on the electronics can cause a short circuit.
Where the liquid comes from
- Water left over from washing up on the handle or the underside of the bowl. Dry the bowl well before fitting it.
- Drips from the lid or the Varoma running down when you lift them off.
- Boiled over. Larger quantities than in the recipe boil over easily above 90 °C. On the TM6, from 95 °C put the simmering basket on the lid instead of the measuring cup.
- Too full. Never fill above the “max” mark (2.2 litres).
- Knife or seal. If the knife isn’t fitted properly, the seal is worn or the bearing has play, liquid leaks out at the bottom.
What you can check yourself
- Empty the bowl and remove the knife as described in the user manual.
- Look at the knife seal: if it is cracked, porous or misshapen, the seal or the knife needs replacing.
- Check the knife: it mustn’t move up or sideways. If it wobbles, the bearing is worn.
- Refit and lock the knife properly. Test with 1 litre of water to see whether the bowl stays watertight.
If it’s still wet after these steps, or liquid got inside the base unit, have the Thermomix® checked. Use only original parts for the knife and seal: parts that don’t fit can leak and affect the warranty.
