Drain error

Unplug the washer before any cleaning or maintenance.
Why
LG: "Disconnect this appliance from the power supply before cleaning and attempting any user maintenance. Turning the controls to the OFF position does not disconnect this appliance from the power supply." "Do not repair or replace any part of the appliance. All repairs and servicing must be performed by qualified service personnel unless specifically recommended in this owner's manual. Use only authorized factory parts." (Front-load manual p.5; top-load manual p.5.) Front-load manual p.27: "Opening the drain filter will result in water overflowing if there is water in the drum. Use a bucket if the drum is not completely drained before you open the drain filter." LG (p.6): "Do not touch draining water which may be hot."

    If the hose and filter are clear and OE returns, book service.

    Why & details

    Call a pro.

    LG's listed OE checks are the drain hose and the drain pump filter. If those are clear and OE keeps returning, have the washer checked by qualified service personnel. Do not open the cabinet or replace the pump yourself.

What OE means

The washer cannot drain. LG points to the drain hose (kinks, clogs, height) and, on front-loaders, a clogged drain pump filter.

The front-load maintenance section adds: "An OE message blinks on the display when the drain pump filter is clogged with dirt" (p.27).
