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
Your Samsung washer displays dE when the door lock switch does not confirm that the door is securely latched and locked. The washer will not start a cycle unless the door lock assembly sends a closed-and-locked signal to the main control board. This protects against water leaks and prevents the door from opening during a spin cycle.
Common Causes
Door not fully closed
The door appears closed but the latch has not engaged the strike on the frame. Clothes caught in the door seal, a warped door frame, or not pushing the door firmly enough prevents full closure.
Faulty door lock assembly
The electric door lock mechanism (also called the door interlock or door switch assembly) uses a wax motor or solenoid to engage the lock. This component fails over time and stops sending the lock confirmation signal.
Broken door latch or strike
The plastic latch hook on the door or the strike plate on the washer frame cracks or wears down. The latch no longer catches and holds the door securely.
Damaged door hinge
A sagging or bent door hinge causes the door to hang at an angle. The latch no longer aligns with the strike, preventing a clean engagement.
Wiring fault to the door lock
The wire harness between the door lock assembly and the main control board is damaged, pinched, or has a loose connector. This breaks the lock confirmation signal.
How to Fix It
- 1
Check for obstructions
Open the door and inspect the rubber door gasket (boot seal) all the way around. Pull back the folds and remove any clothes, small items, or debris stuck in the seal. Check that nothing is caught between the door glass and the gasket.
- 2
Close the door firmly
Push the door closed until you hear and feel the latch click into the strike. On Samsung front-loaders, the latch is at the right side of the door opening. You should hear a mechanical click followed by an electronic click as the lock engages. If you do not hear the second click, the lock assembly is not activating.
- 3
Inspect the door latch and strike
Look at the plastic latch hook on the door and the strike opening on the washer frame. Check for cracks, chips, or wear on the latch. If the latch is broken, it will not grab the strike properly. A cracked latch requires a new door latch assembly, which is a separate part from the door lock.
Unplug the washer before inspecting any components.
- 4
Test the door lock assembly
Unplug the washer. Remove the door lock assembly by opening the door, peeling back the boot seal retaining band with a flathead screwdriver, folding the seal away from the lock area, and unscrewing the two or three Torx T20 screws holding the lock. Disconnect the wire harness. Set a multimeter to ohms and test continuity across the lock switch terminals. Refer to your model's wiring diagram for the correct terminal pairs. No continuity on the switch circuit means the lock assembly is bad.
- 5
Check the door hinge
Open and close the door slowly. Watch whether the latch aligns cleanly with the strike opening. If the door sags or the latch hits above or below the strike, the hinge is bent. Remove the door by supporting it and removing the hinge screws with a Phillips screwdriver. Inspect the hinge pin and mounting holes. Replace the hinge if it is bent or the mounting holes are wallowed out.
- 6
Power cycle and test
After correcting the issue, plug in the washer. Close the door and listen for the double click (latch engaging, then lock activating). Press Power, select a Quick Wash cycle, and press Start. If the cycle begins, the dE code is resolved.
When to Call a Professional
Call a technician if the door lock assembly fails the continuity test, if the door hinge needs replacement, or if the error persists after confirming the latch and strike are intact. TruePro's $59 diagnostic is credited toward the repair. All work is backed by a 90-day warranty on parts and labor. Same-day service is often available. Call 877-378-3111 to book in LA County, Orange County, or Ventura County.
