Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
For C52 on TM6, clean and dry the bowl pins. On TM5, if you used very cold food or a fridge-cold bowl, empty it, rinse with warm water, dry it and resume the recipe swiftly; otherwise clean the contacts and refit the bowl. Contact Vorwerk if C52 persists.
Safety first
Stop and check this first
- Never fit the mixing bowl while its underside contact pins are still damp after cleaning for C52: Vorwerk warns that moisture on the pins can cause rust inside the central unit.
- Never put your fingers into the openings intended for the contact pins on the base of the mixing bowl or insert any objects into them during C52 checks, and always switch off and unplug the base unit before cleaning.
Safe checks you can perform
- Rinse the bowl with warm water if C52 followed cold food

- Refit the dry mixing bowl and escalate if C52 persists

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Rinse the bowl with warm water if C52 followed cold food
- Who:
- you, on TM5, if C52 followed very cold or frozen food or a bowl taken from the fridge.
- How:
- take the contents out of the mixing bowl, rinse the bowl with warm water, thoroughly dry the bowl and underside contact pins, put the contents back in and carry on with the recipe as swiftly as you can.
- Result that matters:
- check whether the TM5 procedure allows the recipe to continue without C52.
- If C52 does not return once the bowl is warmed:
- always work swiftly with very cold and frozen ingredients.
- If you use TM6, no cold food or fridge-chilled bowl was used, or C52 reappears:
- clean and dry the contact pins.
- Evidence to keep:
- whether very cold or frozen food or a chilled bowl preceded C52 and the result after rinsing with warm water.
