Error Code dE
The dE error code signals that the door lock switch is not engaging. Your LG washer refuses to start any cycle until the door is securely latched and the lock mechanism confirms a closed position to the control board. The dE1 variant points to the lock mechanism itself, while dE2 relates to the door switch circuit.
Common Causes
Door not fully closed: Clothing caught in the door seal prevents a full close. The latch does not click into the strike plate, and the lock switch never engages.
Worn or broken door latch: The plastic latch hook on the door wears down over time or snaps off. Without a solid hook, the strike cannot hold the door shut.
Failed door lock assembly: The electromagnetic door lock assembly mounted in the washer frame receives a signal to engage but the internal actuator is burned out. The door closes physically but the electronic lock never activates.
Damaged door boot seal: A torn or displaced rubber door boot gasket pushes the door outward slightly. The latch cannot reach the strike, and the lock switch reads open.
Faulty wiring to door lock: The wire harness connecting the door lock assembly to the main control board has a broken wire or corroded connector. The signal never reaches the board.
DIY Troubleshooting
Check for obstructions: Open the door and inspect the rubber door boot seal. Run your hand around the entire gasket and remove any clothing, lint, or debris caught between the seal and the door frame. Check that the seal is seated evenly in its groove with no folds or bunching.
Inspect the door latch and strike: Look at the plastic hook on the door that inserts into the lock assembly on the washer frame. Wiggle it — it should be firm with no cracks. Check the metal strike plate on the frame for bending or misalignment. A broken latch hook requires a new door latch assembly (LG part varies by model).
Test the door lock assembly: Unplug the washer. Remove the screws holding the door lock assembly to the front panel (usually two Torx T20 screws). Disconnect the wire harness. Use a multimeter set to continuity and test across the lock switch terminals. With the door latch inserted, the switch should show continuity. No continuity means the lock assembly is bad and needs replacement.
Inspect the wiring harness: With the washer unplugged and the front lower panel removed, trace the wires from the door lock to the main control board connector. Look for chafed insulation, burned connectors, or loose pins. Reseat the connectors firmly on both ends.
Reset the washer: Plug the washer back in and attempt a cycle. Close the door firmly until you hear a distinct click, then a second click as the electronic lock engages. If the dE code reappears, the lock assembly or control board needs professional attention.
