LG Washing Machine dE Error Code

Door not locked before cycle start

What this error means

dE (also shown as dE1 or dE2 on some displays) means the washer will not fill or spin because the door lock switch never reported a locked position. LG front-loaders require a confirmed latch before the inlet valves open.

Common causes

  • Clothing trapped in the door gasket preventing full closure
  • Misaligned door strike not pressing the latch switch
  • Broken door hook on the door assembly
  • Failed door lock motor or wiring harness at the hinge

Step-by-step fixes

  1. 1Remove any fabric from the gasket fold and press the door until you hear a single lock click
  2. 2Inspect the strike plate on the cabinet frame for looseness and retighten mounting screws
  3. 3Power-cycle by unplugging for two minutes, then close the door firmly and restart
  4. 4Listen at the lock during start—a buzzing with no click suggests a failed latch motor

When to call a technician

Replace the door lock assembly through a technician if the door physically closes but dE persists every cycle.
