Washer door does not click locked at cycle start, triggering a dC or door-lock error code and preventing the wash program from running.
After the cycle ends the door remains locked and will not open, trapping laundry inside — caused by a failed solenoid that cannot release the latch.
Machine powers on but pressing Start does nothing; the control board does not detect a locked door signal from the faulty interlock switch.
Door locks and unlocks randomly; the washer may start one cycle and then refuse to start the next, indicating a worn or intermittently open switch contact.
Samsung-specific door check fault codes displayed on the panel, directly caused by the door lock switch failing to send a confirmed-lock signal to the main control board.
💡 Pro Tip: Diagnosing a Faulty Samsung Door Lock Switch
Your part is likely the culprit if you notice any of the following:
⚠️ Washer displays error code dC, dC1, dC2, or door-lock fault at the start of a cycle
⚠️ Door clicks but washer will not start — drum stays locked or won't lock at all
⚠️ Cycle completes but door remains locked and will not release for several minutes
⚠️ Intermittent lock failures — machine starts sometimes and refuses others
🔍 Diagnostic tip: With the washer unplugged, use a multimeter to test continuity across the lock's switch terminals. A good door lock switch shows continuity when the door striker depresses the actuator. No continuity (or infinite resistance on the solenoid winding) confirms the lock is defective and needs replacement.
