Washer door closes but will not latch or lock, preventing the cycle from starting.
Control board displays a door-lock error code and the machine refuses to run.
Machine powers on but will not begin any cycle because door lock signal is never sent to the control board.
Washer starts normally but stops partway through the cycle and unlocks the door unexpectedly.
Door locks inconsistently — works sometimes but fails randomly, causing repeated error resets.
💡 Pro Tip: How to Diagnose a Failing Door Lock Switch
Your part is likely the culprit if you notice any of the following:
⚠️ Washer displays a DC, dC, or door-lock error code and refuses to start
⚠️ Door feels closed but the machine will not begin the wash cycle
⚠️ Washer starts and then stops mid-cycle, then unlocks the door unexpectedly
⚠️ Door lock clicks repeatedly but never engages, or lock mechanism feels loose or broken
🔍 Use a multimeter set to continuity mode: with the door depressing the latch plunger, you should read continuity across the switch terminals. An open circuit confirms the switch is faulty and must be replaced. Also inspect the wiring harness connector for corrosion or bent pins before ordering.
