What dE means (lg de error)
An lg de error (also shown as dE1 or dE2) means an LG washer cannot confirm the door is locked. The control must lock the door before filling; when it cannot verify a secure lock it raises dE and holds the cycle for safety, often simply because the door is not pushed fully shut.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your LG Washer. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, or recent service.
- The display shows “dE”, “dE1”, or “dE2”
- The cycle will not start or pauses right away
- The door does not click securely when closed
- Laundry may be caught in the door seal
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level check from a problem that needs trained service and the correct LG parts.
- Door not fully closed — laundry or the seal blocks a clean latch
- Misaligned strike or latch — the latch does not engage
- Failed door lock assembly — the lock will not confirm a secure close
- Wiring or control fault — the lock signal is lost
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where high-voltage parts, gas, the sealed refrigeration system, or a heat-pump compressor are involved, and hand the rest to a qualified technician.
- Open the door, clear any laundry from the seal, and close it firmly until it clicks.
- Check the latch and strike for damage or obstruction.
- Power the washer off at the breaker for two minutes, then retry.
- If dE persists with the door fully shut, leave it for service.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the door lock assembly, door latch/strike, door switch, and control board. The correct part for your LG Washer is matched from the model and serial number, and genuine LG components are fitted rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
A persistent dE with the door fully closed needs a technician to test the door lock assembly and its wiring. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.

Prevention and care
Regular care keeps this condition from returning on your LG Washer. Keep filters, vents, and the condenser or exhaust path clean, avoid overloading or blocking airflow, check that doors and seals close cleanly, and follow the LG maintenance guidance for your model. Because this unit relies on electronic control, protect it with a stable, correctly rated power supply and have any built-in or laundry installation done to LG specification so the control never sees an out-of-range condition. If a code appears, note exactly what was shown before you reset the appliance — that record helps the technician reach an accurate diagnosis and avoid replacing parts unnecessarily.
