LG Error Code dE
Door lock error
Common Causes
- 1Item in door gasket
- 2Latch failure
- 3Lock motor issue
Step-by-Step Troubleshooting
- 1
Inspect the rubber door boot seal (gasket) for small clothing items, socks, or debris lodged between the seal and the door preventing full closure
- 2
Clean the door latch area and the strike plate on the washer body — soap residue buildup can prevent the latch from seating properly
- 3
Close the door firmly and listen for the lock mechanism engaging — you should hear a distinct click followed by a brief whirring of the lock motor
- 4
If the lock clicks but the error persists, the door switch (micro-switch inside the lock assembly) may have failed — test with a multimeter for continuity when the door is locked
- 5
Check the wire harness from the door lock assembly to the main control board for pinched or severed wires at the hinge flex point
Pro Diagnostic Tip
The dE1 vs dE2 suffix on LG washers specifies the failure mode: dE1 means the door cannot lock at cycle start, dE2 means the door cannot unlock after the cycle (PTC lock timeout). For dE2, wait 3 minutes after cycle end — the PTC device needs cool-down time to release.
You Might Also Notice

- •Door remains locked after cycle completes
- •Clicking noise from door latch area
- •Cycle will not begin despite pressing start
