How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker. Turn off power and leave it off until the fault is found.
- Inspect for leaks: Remove the toe-kick and check for water in the base pan or on wiring.
- Check wiring: Look for burned, pinched, or exposed wires, especially near the door hinge and base.
- Test major loads: With components disconnected, test the heater, circulation pump, and drain pump for shorts to ground using a multimeter. Replace any component that shows continuity to chassis.
- Repair and retest: After replacing faulty parts and repairing wiring, restore power and run a short cycle while monitoring.
