Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the unit before adjusting hinges or accessing switches.
Steps to fix dO/DO:
- Check for obstructions: Remove the basket and any accessories. Ensure nothing is protruding that could prevent the door from closing fully.
- Inspect gasket: Examine the door gasket for deformation, tears, or hardened sections. Replace if it does not seal evenly around the door.
- Check door alignment: Look at the door from the side and top to see if it sits evenly in the frame. Gently adjust hinges if the design allows, or tighten loose hinge screws.
- Test door switch: Access the door switch assembly and test continuity with a multimeter while manually actuating it. Replace the switch if it fails to change state reliably.
Note: Proper door closure is critical for safe operation. Do not bypass the door switch.
