How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker. Unplug the appliance and leave it disconnected until the fault is found. There is a risk of electric shock and fire.
- Step 1 – Visual Inspection: Check for obvious water leaks, burnt smells, or scorch marks around the rear and underside of the appliance.
- Step 2 – Heater Insulation Test: Disconnect the wash heater and dryer heater one at a time and test the insulation resistance between each terminal and earth. Replace any heater exhibiting low insulation resistance.
- Step 3 – Motor and Wiring Harness Inspection: Inspect the motor and its wiring harness for damage. Test insulation to earth. Replace any faulty components.
- Step 4 – Professional Assistance: If you lack the necessary insulation test equipment or cannot locate the fault, contact a qualified appliance electrician.
