Quick answer

Check mixing bowl and lid position when C144 is displayed
- Who:
- you, with the Thermomix TM6 or TM5 stopped and without using force on the lid or locking mechanism.
- How:
- make sure that both the mixing bowl and the mixing bowl lid are positioned correctly on the appliance before trying to lock the lid again.
- Result that matters:
- check the bowl and lid position as Vorwerk instructs for C144.
- If the lid locks into position and C144 clears:
- note that repositioning the bowl and lid resolved it.
- If C144 persists with the bowl and lid positioned correctly:
- on TM6, clean debris from the arms and lid; on TM5, try another bowl if available.
- Evidence to keep:
- affected TM5 or TM6 model and whether C144 cleared after positioning the bowl and lid.
