How to Fix / Troubleshooting
Safety first: Disconnect power before removing the door panel.
- Confirm door closure: Ensure the door closes firmly and that racks or tall dishes are not preventing full closure.
- Check for error indicators: Some Grundig models show a door symbol or blink LEDs when the door is not recognized as closed. Refer to the user manual.
- Inspect door latch and lock: Check the latch on the tub and the lock in the door for damage or looseness. Tighten screws and adjust alignment if necessary.
- Test Start button: If the door is recognized but Start does nothing, the Start button or user interface PCB may be faulty. Remove the inner door panel and inspect the PCB for damage or moisture.
- Replace faulty components: Replace the door lock assembly if the switch does not change state when latched. Replace the user interface PCB if the Start button is unresponsive.
