Possible Causes
Loose ribbon cable between UI and main board, failed user interface PCB, liquid ingress into control panel, firmware communication error
How to Fix / Troubleshooting
Safety first: Disconnect power before removing the control panel.
Check UI connections:
- Remove the top cover and then the control panel fascia as per service instructions.
- Inspect the ribbon cable or harness between the user interface board and the main control board; reseat both ends firmly.
- Look for signs of moisture, detergent residue, or corrosion on the UI board; dry gently and clean with isopropyl alcohol if minor.
- If buttons or display segments are unresponsive and F12 persists, the UI board may need replacement.
- If a new UI does not resolve the issue, the main control board communication circuit may be defective and require professional service.
