How to Fix / Troubleshooting
Safety first: Do not repeatedly reset the breaker. Unplug the Thermomix immediately and keep it unplugged until inspected.
- Check cord and plug: Inspect for visible damage. Do not use the appliance if the cord or plug is compromised.
- Drying (if moisture suspected): If the unit was exposed to spills, allow it to dry in a warm, dry place for at least 24–48 hours, then test on an RCD-protected outlet. If it still trips, discontinue use.
- Professional insulation test: Earth leakage and shorts must be diagnosed with proper test equipment. Arrange service with an authorized technician.
