If your LG washer is showing the dHE error code, it typically points to a door/handle/lock issue that prevents the machine from detecting a proper door closure. The dHE code often appears on front-load and washer‑dryer combo models when the door handle sensor, latch or interlock does not register a secure lock. You may see the cycle stop or refuse to start, experience incomplete spins, abnormal pauses, or — on combo units — longer drying times because the washer cannot advance through the full program. Aside from inconvenience, a faulty door lock can create safety risks (door opening mid‑cycle, potential water leaks), increase wear on other components, and leave clothes soaked because the spin stage won’t run. Understanding why dHE occurs helps you diagnose whether it’s a simple contact problem or something requiring parts or professional service.
Common causes
- Door not fully closed or an obstruction caught in the door seal (coins, clothing edges, rags).
- Faulty door handle or latch mechanism preventing a full catch.
- Defective door lock / interlock switch (electrical failure in lock assembly).
- Worn or damaged door hinge or door alignment issues causing poor seal.
- Loose or damaged wiring harness to the door lock or control board.
- Main control board or user interface fault not recognizing lock status.
- Water, corrosion or physical damage to the lock or latch sensors.
- Firmware or software glitch (less common) causing false error reporting.
Troubleshooting steps
- Power reset: Unplug the washer (or switch off breaker) for 1–2 minutes, then restore power — this clears temporary glitches and can reset the lock sensor.
- Check the door: Open and close the door firmly. Remove any clothing or debris from the seal and make sure nothing blocks the latch from engaging.
- Inspect the door handle and latch: Look for visible cracks, broken plastic, or loose parts. If the handle feels loose or doesn’t fully engage the catch, the latch or handle may need replacing.
- Test the lock: On many LG washers you can enter service/diagnostic mode (consult your manual) to test the door lock actuator. If the lock fails to engage during the test, the lock assembly is likely faulty.
- Check wiring and connectors: With the washer unplugged, inspect the wiring harness to the door lock for loose connectors, pinched wires, or corrosion. Re-seat connectors if accessible.
- Realign or replace hinges/seal if needed: If the door sits unevenly or the gasket is distorted, adjust or replace the hinge or seal so the latch can engage properly.
- Run a diagnostic cycle: If available, run a built‑in diagnostic to capture error history and confirm dHE persists after basic checks.
- Swap or replace suspect parts: If tests indicate the door lock/handle/latch is bad, replace the assembly with OEM replacement parts. If wiring and lock check good, consider the main control board as the next susp
