How to Fix / Troubleshooting
Safety: Do not repeatedly reset the breaker. Unplug the appliance and keep it unplugged until inspected.
- Check for moisture: Inspect around the motor housing and heater for signs of water. Dry thoroughly and identify leak source.
- Inspect power cord: Look for cuts or crushed sections. Replace the mains cable if damaged.
- Test heater and motor: With a multimeter, check resistance to earth from the heater and motor. Any low resistance indicates insulation failure and the part must be replaced.
- Check suppression capacitor: Replace the EMI suppression capacitor if it shows signs of cracking or burning.
Because this involves safety-critical insulation, professional service is strongly recommended.
