Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the dishwasher before removing the control panel.
Step-by-step checks:
- Check mains stability: Ensure the outlet is not shared with heavy loads that cause voltage dips.
- Inspect control panel connections: Remove the inner door panel and reseat the ribbon cable or connectors between the display and main board.
- Look for moisture: Check for condensation or water traces inside the control panel area. Dry thoroughly and identify any door seal issues that may allow steam ingress.
- PCB inspection: Examine the main board for bulging capacitors or burnt components in the low-voltage power supply section. Replace the board if defective.
If flickering persists after reseating connectors, a new control panel or PCB may be required.
