How to Fix / Troubleshooting
Safety first: Unplug the washer before working on the door lock.
- Confirm door closure: Ensure the door is fully closed and pressed firmly until you hear the latch engage.
- Inspect latch and strike: Look for cracks or wear on the latch and door strike. Replace if damaged.
- Access door lock: Remove the front panel or loosen the door gasket clamp to reach the door lock assembly. Check that the wiring connector is secure.
- Test lock: With a multimeter, test the lock coil for continuity. An open coil indicates a failed lock that must be replaced.
- Replace assembly: Install a new Comfee-compatible door lock assembly, reattach wiring, and re-secure the door gasket.
