Bauknecht User Interface Keypad Failure

Control panel buttons are unresponsive, or only some buttons work intermittently.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn or damaged membrane switches, moisture ingress into the control panel, loose ribbon cable to the main board, faulty UI PCB.

Safety first: Disconnect mains power before removing the control panel.

Power reset: Unplug for 5 minutes, reconnect, and test; minor glitches can clear.
Clean the panel surface: Wipe with a slightly damp cloth; do not allow liquid to enter around the buttons.
Access the UI board:
- Remove the top cover.
- Unscrew and gently pull out the control panel.
- Check the ribbon cable connection to the main board.
Inspect for moisture or corrosion: If present, dry carefully; if corrosion is severe, replace the UI board.

Note: Avoid spraying cleaners directly onto the control panel; apply to a cloth first.
