Error codeEd4
ApplianceWasher
Quick answer
Ed4 means the softener reservoir level did not decrease and an open circuit is detected in the softener pump.
Model compatibility: LG reuses codes across series and model years, so Ed4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
An open circuit in the softener pump is detected.
The Ed4 code tells an LG front-load washer or WashTower owner that the softener reservoir did not empty as expected. An open circuit in the softener pump is detected.
Manual guidance
Confirm the softener is liquid, because powder softener should go into the drum by hand. Take residue out of the tray when it could be in the way of the flow. If it persists, request service.
Nearby codes
Ed3 is the softener pump fault in the same series, and Ed5 is a communication issue.
