What Does Error Code dE Mean on a LG Washing Machine?

Door open or door lock failure.

The control board monitors the door interlock switch to confirm the door is physically closed and the lock solenoid has engaged before allowing the drum to spin. dE fires when that confirmation is missing—either the latch never seated or the lock circuit never reported locked. dE1 and dE2 narrow the fault to specific lock states, distinguishing a door reported open from a lock that failed to actuate or unlock, helping separate a simple latching issue from a solenoid or wiring failure.

Models affected: LG front-load washers with an electronic door interlock (dE/dE1/dE2); the dE1/dE2 variants appear on newer front-loaders such as WM3900HWA, WM4000HBA, WM4500HBA, and WM8100HVA. Top-load models like WT7300CW use a lid-lock scheme and typically report door faults differently.
What owners report: Owners commonly report this code right after loading, often traced to a sock or small garment wedged in the gasket that keeps the door from seating fully. Many say a firm push until it clicks clears it; when the door clicks but the code persists, the latch or lock assembly is the more likely culprit.

  2. 2

    Close door firmly

    Push the door until it clicks definitively.

  3. 3

    Inspect the door catch

    Look at the door latch hook and the catch bracket. If the plastic is cracked or bent, replace the assembly.

Frequently Asked Questions

Can I keep using my LG Washing Machine when error dE appears? +
You often can for a cycle or two, but the door issue behind dE will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes dE on a LG Washing Machine? +
Across reported LG washing machine repairs, the most frequent is laundry or fabric caught in the door seal (40% of cases), door latch worn or broken (30%), then door lock solenoid failure (20%). Check them in that order before replacing any parts.
dE keeps coming back after a reset — what should I check next? +
A reset only clears the stored dE fault; if it returns, the door problem is still present. Move on to the physical checks — check for laundry in the door seal, then close door firmly — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix LG Washing Machine error dE? +
A DIY repair typically runs $25–$90 in parts, versus $150–$300 for a professional service call, so handling it yourself saves around $125. Expect the work to take roughly 30–60 minutes.
Which LG Washing Machine models show error dE? +
dE is documented on LG front-load washers with an electronic door interlock (dE/dE1/dE2); the dE1/dE2 variants appear on newer front-loaders such as WM3900HWA, WM4000HBA, WM4500HBA, and WM8100HVA. Top-load models like WT7300CW use a lid-lock scheme and typically report door faults differently.. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
