Whirlpool Washer - F26 Error Code

Door switch failure detected.

Meaning

Door switch failure detected.

The F26 error indicates that the washer’s door switch is not providing the correct open/closed status to the control board. Whirlpool Duet washers rely on both a door lock mechanism and a door position switch. If the control board receives inconsistent or missing signals from the door switch, the washer triggers F26 and halts operation. This error is common when the switch wiring becomes loose, the switch fails internally, or the door hinge is misaligned.

Symptoms

  • Washer will not start
  • Door appears closed but washer does not detect it
  • F26 appears immediately after pressing Start
  • Intermittent cycle interruptions

Causes

  • Faulty door switch
  • Loose or damaged wiring harness
  • Door hinge misalignment
  • Control board misinterpreting switch signals

Step-by-Step Fixes

  • Inspect the door switch wiring harness.
  • Test the door switch for continuity.
  • Replace the door switch if faulty.
