Error Code dE

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.

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. 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.
