LG Washer Error Code dE

The dE code on an LG washer stands for door error, indicating that the machine cannot confirm the door is properly closed and latched before or during a cycle. It is triggered by a switch contact failure in the door lock assembly, which can result from a damaged door hook, a broken door lock switch, or faulty wiring connections at the switch terminals. The washer will not operate while this code is active as a safety precaution.

No, you should not attempt to run the washer while the dE error is active. The code indicates that the door lock cannot be confirmed as secure, and running the machine in this condition risks water leakage from an unlatched door. The washer is designed to prevent operation when this error is present, and the underlying cause should be resolved before using the appliance.

If the issue is a loose or disconnected terminal connection, there may be no parts cost involved, only the time to inspect and reseat the wiring. If the door hook needs replacement, parts typically range from $10 to $40 depending on the model. A door lock switch assembly replacement usually costs between $20 and $70 for the part, with additional labor costs if a technician is performing the repair.

Start by checking the wiring terminals at the door lock switch for any loose, disconnected, or visibly damaged connections. Next, inspect the door hook for deformation or breakage and confirm it fully engages the lock receiver when the door is closed. If the terminals and hook are in good condition but the error persists, the door lock switch assembly likely needs to be replaced. Avoid forcing the door open during a cycle, as this can damage the hook and lock components.

A reset may temporarily clear the dE code from the display, but if the underlying cause is not fixed, the error will return as soon as the machine attempts to verify the door lock again. A reset is not a repair. The door hook, lock switch terminals, and lock assembly should be inspected and repaired before assuming the issue is resolved.
