How to Fix / Troubleshooting
Safety first: Do not repeatedly reset the breaker. Unplug the dryer and keep it disconnected until the fault is found. Risk of electric shock and fire.
- Visual inspection: Check the mains cable and plug for damage or burns. Replace if faulty.
- Inspect heater and wiring: Remove the rear panel and look for signs of arcing or burnt insulation around the heater and wiring.
- Insulation test (for professionals): Use an insulation tester to check for leakage between live parts and earth. Replace any component (heater, motor, filter) that shows low insulation resistance.
- Dry out moisture: If the dryer has been exposed to water, allow it to dry completely in a warm, ventilated area before retesting. If tripping continues, seek professional service.
