Possible Causes

Faulty door switch feedback circuit, loose door switch wiring, defective user interface board, main control logic fault

How to Fix / Troubleshooting

Safety First: Unplug the washer before removing the console or front panel.

Step-by-step checks:

  • Door switch feedback: Verify that the door lock/switch assembly properly signals the control when the door is closed and locked (check continuity on feedback contacts).
  • Inspect UI connections: Remove the control console and check the ribbon cable and harness between the UI and main control.
  • Check for moisture: Look for signs of moisture intrusion into the console that could cause intermittent operation.

When to replace: Replace the door lock assembly if feedback contacts are faulty. If the UI is unresponsive or erratic with good wiring, replace the user interface board. Persistent F26 may require main control replacement.
