Possible Causes
Loose ribbon cable between UI and main board, Moisture intrusion into control panel, Failed touch keypad or UI PCB, Faulty main control board communication circuit
How to Fix / Troubleshooting
Safety first: Disconnect power before opening the door panel or control housing.
- 1. Power reset: Turn off the breaker for 5–10 minutes, then restore power to see if the error clears.
- 2. Inspect control panel: Remove the inner door panel to access the user interface board. Check the ribbon cable connection between the UI and main control board; reseat it firmly.
- 3. Look for moisture: Signs of condensation or water inside the control area indicate a door seal or vent issue. Dry the area thoroughly and correct any gasket problems.
- 4. Test keypad: If certain buttons never respond, the touch keypad or UI PCB is likely defective and should be replaced as an assembly.
If E11 persists after reseating cables and drying, the main control board may need replacement by a qualified technician.
