How to Fix / Troubleshooting

Safety first: Disconnect power before opening the door panel.

  • Reset power: Unplug for 10–15 minutes, then reconnect and test.
  • Inspect UI-to-main-board cable: Remove the inner door panel and check the ribbon cable between the display/control module and the main PCB. Reseat both ends.
  • Check for moisture damage: Look for signs of condensation or corrosion on the control electronics. Dry gently if damp.
  • Professional service: If the error persists, the main PCB likely needs replacement.
