Possible Causes
Damaged keypad membrane, Loose ribbon cable between keypad and control board, Water intrusion into control panel, Faulty display board
How to Fix / Troubleshooting
Safety first: Turn OFF power before removing the front control panel.
- Inspect panel for damage: Look for cracks, UV damage, or signs of water ingress around the keypad area.
- Check ribbon cable: Remove the control panel cover and locate the flat ribbon cable connecting the keypad to the main board. Ensure it is fully inserted and not kinked or torn.
- Dry moisture: If condensation or water is present, dry the area thoroughly and correct any gasket or cover issues that allowed water in.
- Test buttons: Restore power and test each button. If some or all buttons are unresponsive and E10 remains, the keypad/display assembly likely needs replacement.
Warning: Do not spray cleaners directly onto the keypad; apply to a cloth first to avoid future water intrusion.
