How to Fix / Troubleshooting
Safety first: Isolate power before removing the front panel.
- Power cycle: Turn off the boiler at the fused spur for a few minutes, then restore power to see if controls recover.
- Inspect control panel (engineer task): Remove the fascia and check the ribbon cable between the display/control board and main PCB. Reseat if loose.
- Check for moisture: Look for signs of water ingress from above. Any leak must be fixed before replacing electronics.
- Replace control panel or PCB: If the keypad or encoder is physically damaged or unresponsive, the engineer should replace the front control board or main PCB as appropriate.
