How to Fix / Troubleshooting
Safety first: Isolate the appliance from mains power.
- Access lock assembly: Remove the top panel or front fascia to reach the door lock mechanism.
- Check connectors: Ensure all plugs on the lock motor and position switches are firmly seated.
- Test position switches: Use a multimeter to verify that the lock-closed and lock-open switches change state when the latch moves. Replace the lock assembly if switches are faulty.
- Adjust lock: If the latch does not fully engage, adjust its position according to the service manual.
Warning: Do not attempt self-clean cycles until door lock errors are resolved.
