What Our Customers Say
"I am so happy with the services provided by TruePro Home Services! I have a very old oven that I truly believed would need to be replaced. But, Yury came on time, diagnosed the issues, and had the parts with him to do the repair the same day. My oven is now in perfect working order. Highly recommend!"

"Our LG Front Loading washer wasn't draining. I contacted Simon the next day. He had the part on his truck and came by within 30 minutes, and had it up and running super fast! Thank you Simon for your punctuality, honesty and great value. See you next time!"

"Wonderful and top notched care! They were able to meet my same day expectation to get a washer and dryer hooked up in a new house. He was attentive, thoughtful and explained it all as well. I would highly recommend their service!"

What Error Code dE Means
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.
How to Fix It
- 1
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.
- 2
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 β 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).
- 3
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.
Unplug the washer before removing any panels or disconnecting wiring.

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.
- 5
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.
When to Call a Professional
Call a technician if the latch is physically broken, the lock assembly tests bad with a multimeter, or the code keeps coming back after you have checked everything. TruePro's $59 diagnostic fee is credited toward the repair. All work includes a 90-day warranty on parts and labor (CA License #51112). Same-day service is often available in LA County, Orange County, and Ventura County. Call 877-378-3111. Save 15% on labor with code NEW15 if you are a new customer.
