Possible Causes
Loose connection between user interface and main board, Moisture in control panel, Failing power supply on control board, Fluctuating mains voltage
How to Fix / Troubleshooting
Safety first: Unplug the dishwasher before removing any panels.
- Check mains connection: Ensure the plug is firmly inserted and the outlet is not loose.
- Inspect UI connections (experienced users): Remove the inner door panel to access the user interface board. Check ribbon cables and connectors for secure fit and signs of corrosion.
- Dry moisture: If condensation is present inside the control panel, allow it to dry completely before reassembly. Avoid spraying water directly on the control area when cleaning.
If flickering persists, the user interface or main control board may need replacement.
