💡 Pro Tip: How to Diagnose a Faulty WH10X20821 Door Lock
Your part is likely the culprit if you notice any of the following:
⚠️ Washer door won't latch, close, or lock properly
⚠️ Washer won't start a cycle even though the door appears closed
⚠️ E27 error code displayed on the control panel
⚠️ Door locks and immediately unlocks without starting the cycle
Before ordering, unplug the washer and use a multimeter to test the door lock switch for continuity. No continuity = confirmed failed lock assembly. Also check the wiring harness connector for corrosion or loose pins before replacing the lock.
