LG Washer dE Error Code: What It Means and How to Fix It
Updated · from manufacturer service documentation
On LG's WT5070C platform, dE means a door/lid error — the control isn't confirming the doorlock switch is sensing the lid correctly. On a different LG platform (top-load, MFL40322141 series), the same two letters can also surface alongside a drain-related pressure-switch check if DE displays even though water is actually draining normally. Check which behavior matches your washer before assuming the cause.
What Causes the dE Code
| Cause | Likelihood | DIY difficulty | Related part |
|---|---|---|---|
| Doorlock switch not sensing the lid correctly | Most common | Moderate — check switch/magnet sensing | Doorlock switch |
| Doorlock switch or PCB needs replacing | Less common | Moderate — component swap | Doorlock switch / PCB |
| (Topload platform only) Pressure switch defective, DE shows despite normal drain | Less common | Moderate — test-mode frequency check | Pressure switch |
| (Topload platform only) Main board defective | Rare | Pro repair | Main board |
How to Fix the dE Error, Step by Step
-
Check the doorlock switch and lid sensing
Per the service diagnostic, connect another doorlock switch and check the lid sensing by magnet to confirm whether the existing switch is the problem.
-
Replace the doorlock switch or PCB if the check fails
The documented corrective action for this fault is straightforward: replace the doorlock switch or the PCB, depending on which component tests bad.
-
On the top-load platform, if drain water actually leaves normally but DE still displays
This points to the pressure switch instead of the door. In test mode, check the pressure switch frequency with the tub empty: a reading below 26.3 kHz means a defective pressure switch; a reading between 26.3 and 27.1 kHz means a defective main board.

Note how the washer handles an unresolved dE
Per LG's training documentation, if a dE (or PE/tE) error isn't cleared within 20 seconds, the machine shuts off automatically — other error codes get a longer 4-minute window before auto-shutoff.
Which Models This Applies To
Documented for the LG WT5070C service manual (door/lid sensing fault) and the MFL40322141 top-load platform (pressure-switch-related DE display). LG's own training documentation (WM0742HGA) notes that dE/PE/tE errors get a shorter 20-second auto-shutoff window than other codes. If your washer's dE clears with a door/lid check, you're on the WT5070-style platform; if the door checks out fine but the code persists, check the pressure switch per the top-load platform's diagnostic instead.

Frequently Asked Questions
Is dE always a door problem on LG washers?
On the WT5070C platform, yes — it's specifically a door/lid sensing check. On some top-load models, a DE display can persist due to a pressure switch issue even when the door and drain are both fine, so it's worth checking both.
What should I check first if I see dE?
Start with the door: make sure it's closing normally and that nothing is obstructing the lid sensing. If the door checks out and the code returns, move to the drain-related pressure switch check.
Why does dE shut the washer off faster than other codes?
Per LG's training documentation, dE (along with PE and tE) triggers an automatic shutoff after 20 seconds if unresolved, versus roughly 4 minutes for other codes — a documented platform behavior, not a separate fault.
How do I clear the dE code?
Press START/PAUSE to clear the display on most LG washers; if the underlying door or pressure-switch issue isn't actually fixed, the code will return once the affected step of the cycle runs again.
