How to Fix / Troubleshooting

Safety: Disconnect power before opening the control housing.

  • Dry panel: If condensation or splashes have reached the panel, allow it to dry completely. Do not use heat sources that could deform plastic.
  • Check ribbon cable: Open the housing and ensure the keypad ribbon cable is firmly seated on the PCB.
  • Test individual keys: In the service menu (if accessible), test each key. Non-functioning keys may indicate a defective keypad membrane.
  • Replace keypad or PCB: If cleaning and reseating do not help, replace the keypad assembly or the entire control PCB as per Grünbeck parts list.
