What Your Machine Is Actually Telling You
dE means the door lock assembly didn't confirm the door is latched and locked. LG won't start any cycle without door confirmation — this is a safety interlock.
LG's door lock mechanism: A PTC (heater) element expands when energized, pushing a locking pin into position. A confirmation switch then signals the board. The entire process takes 5-8 seconds.
dE vs dE1 vs dE2:
- dE = door not closed or lock not engaging.
- dE1 = door opened during cycle.
- dE2 = door lock switch error.
Common causes:
1. Door not pushed firmly (35%) — didn't close fully.
2. Clothes caught in seal (20%) — preventing full closure.
3. Lock mechanism worn (15%) — PTC degraded.
4. Door hinge sagging (10%) — strike misaligned.
5. Wiring to lock (10%) — connector loose.
6. Main board relay (5%) — not powering lock.
7. Child lock confusion (5%) — CL active.
