LG Washer - OE1 Error Code
The washer detected a drain fault (variant of OE).
Meaning
The washer detected a drain fault (variant of OE).
The LG OE1 error code is a variant of the standard OE drain error. It appears on a small number of North American LG front‑load Direct‑Drive washers and indicates a more specific drain‑related issue. OE1 typically means the washer attempted to drain but the pressure sensor still detected water in the tub after the pump ran.

Model-Specific Notes
- OE1 is a more specific version of OE, triggered when the pressure sensor does not detect water level changes during draining. - WM3700/3900/4000 series models are confirmed to use OE1 in North American firmware. - If OE1 appears repeatedly, the pressure sensor hose is a common failure point.
