dE2
LG Washing Machine
Severity: MinorWhat Does This Error Mean?
The dE2 error means your LG washer's door is not latching correctly. The door switch sensor is telling the machine the door is not fully closed or locked. This is a safety feature — the washer will not run if the door is open. It is usually a simple fix involving the door latch or its sensor.
Affected Models
- WM3900HWA
- WM4000HWA
- WM3700HWA
- WM1388HW
- Most LG front-load washers
Common Causes
- Door not pushed closed firmly enough to engage the latch fully
- A piece of clothing or debris caught in the door seal preventing a full close
- Worn or bent door latch that no longer clicks into place properly
- Faulty door switch sensor not detecting a correctly closed door
- The door hinge has shifted over time causing the door to sit slightly out of alignment
How to Fix It
-
Open the door completely and check the rubber door seal all the way around.
Feel and look for any clothing, socks, or debris caught in the gasket. Even a small item can prevent the door from sealing fully.
-
Close the door firmly with a solid push until you hear it click.
The door needs a definite click to confirm the latch has engaged. A gentle nudge is often not enough.
-
Inspect the door latch on the door and the strike plate on the machine body.
Look for visible damage, bending, or wear. If the latch is broken, it needs to be replaced.
-
Unplug the washer for 2 minutes and plug it back in.
A power reset can clear a dE2 caused by a temporary sensor glitch after the door is properly closed.
-
Start a new wash cycle and observe whether the error returns.
If dE2 clears and the cycle runs normally, the door just needed a firmer close. If it returns immediately, the latch or switch needs professional inspection.
When to Call a Professional
If the door closes and latches but dE2 keeps appearing, the door switch sensor has likely failed. A bad door switch requires disassembly of the door panel to replace. Contact LG support at 1-800-243-0000 or a local appliance repair technician. Expect repair costs of $100–$200 for a door switch replacement.
Frequently Asked Questions
What is the difference between dE and dE2 on an LG washer?
dE means the main door latch is open or not detected. dE2 is more specific — it means the door switch circuit itself has a fault. dE2 can appear even when the door appears physically closed. This usually points to a worn door latch or a failing door switch sensor.
Can I force the washer to run with the dE2 error?
No — and you should not try. The door interlock is a safety feature that prevents the drum from spinning while the door is open. Bypassing it is dangerous and voids your warranty. Fix the door latch or switch properly before running any wash cycle.
How long do LG washer door latches typically last?
A door latch typically lasts 5–10 years with normal use. Frequently slamming the door or overstuffing the drum shortens latch life. If your washer is older and showing dE2 regularly, replacing the latch is a cost-effective fix. The part usually costs $15–$40 and a technician can install it in under an hour.
