Thermomix® error codes: meaning and fix

A message on the display doesn’t mean your machine is broken. Here is what each code means according to Vorwerk and what you can do yourself.

For the TM5 and TM6 · Mixklinik workshop · Updated November 2026

In short

The same number often means something different on the TM5 and the TM6. Many messages disappear once you clean the contact pins on the bowl, let the machine cool down or restart it. A repair is usually only needed if the message keeps coming back.

What to do with any message

  1. Read the display. The TM6 and TM5 usually show a text with the next step next to the number. Follow it first.
  2. Restart. Switch the machine off, wait a minute and switch it on again. That clears many messages.
  3. Check the bowl. Take the bowl out, clean and thoroughly dry the contact pins underneath and refit it until it clicks into place. Wet or dirty contacts are the most common cause.
  4. Let it cool down. Messages about the motor, Turbo or Dough mode are often caused by heat. Let the machine and the contents cool and keep the vents clear.
  5. If it keeps coming back, make a note. Take a photo of the display and note when it appears (recipe, temperature, speed, quantity). That helps with the repair.

Unplug immediately if there is liquid under the bowl or inside the machine, or if it smells burnt or smokes. Don’t switch it on again, don’t tip it over and don’t hold it under water.

Look up every code

Enter the number with or without the “C”, for example 140. Choose your model so you only see the meaning that applies. The model is on the rating plate on the underside of the machine.

Why the same number means different things

Vorwerk assigns codes per model. On the TM5, C52 points to a heating problem in the bowl, often after very cold ingredients; on the TM6 the same code asks you to clean the bowl’s contact pins. C32 is a hardware message on the TM5, while the TM6 shows “Thermomix® is recovering”. So always check the right model.

What about the TM7?

The TM7 has its own messages and is usually still under the manufacturer’s warranty. If you have a problem, contact Vorwerk customer service directly.
