Possible Causes

Loose or damaged harness between UI and main control, Corroded connectors, Failed main control board, Failed user interface board

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing internal controls.

  • Access controls: Remove the inner door panel to expose the user interface and main control (location varies by model; sometimes main control is in the base).
  • Inspect wiring harness: Check the harness and connectors between the UI and main control for pin damage, corrosion, or broken wires. Repair or replace as needed.
  • Reseat connectors: Unplug and firmly reconnect all related connectors to ensure good contact.
  • Board replacement: If wiring is intact and F11 persists, replace the main control board first (most common). If still unresolved, replace the user interface board.

After repairs, restore power and run a diagnostic cycle to confirm communication.
