Washer door latch engages but the lock switch fails to send a closed-door signal to the control board, preventing the cycle from starting.
Control board does not receive a lock confirmation from the door switch assembly, so the washer refuses to begin filling or agitating.
A failed switch mechanism keeps the door electronically locked at the end of the cycle, trapping laundry inside the drum.
Samsung's door error codes E27 and dE are directly triggered by a faulty door lock switch that cannot confirm a secure latch position.
Intermittent switch failure causes the washer to detect an open-door condition during operation, halting the cycle and draining the tub unexpectedly.
💡 Pro Tip: How to Confirm Your Door Lock Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Washer displays E27 or dE error code at the start of a cycle
⚠️ Door feels closed but the control board refuses to start the cycle
⚠️ Door won't unlock at the end of the wash cycle — load is trapped inside
⚠️ Washer starts filling but stops immediately and drains without spinning
🔍 Quick Test: With the washer unplugged, use a multimeter set to continuity mode on the door lock terminals. A healthy lock clicks and shows continuity when the door latch engages the hook. No click or no continuity = replace the lock assembly.
