How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before opening any electrical covers.
- Check power connection: Ensure the plug is firmly inserted and the outlet is not loose. For hardwired units, check the terminal block connections.
- Inspect mains filter and wiring: Remove the lower panel and verify that all connectors to the mains filter and control board are secure.
- Test on different circuit: If possible, temporarily connect the dishwasher to a different circuit to rule out household supply issues.
- Control board repair: If flickering persists, the control board's internal power supply may be failing and the board should be replaced.
