LG Washer Not Draining: Pump Filter, Coin Trap, and OE Error Fix

Quick Answer

LG Washer not draining: clean the drain pump filter first - it is the most common cause and takes 5 minutes. Access it from the small panel at the lower front of the machine. Coins, small clothing items, and hair ties collect here and block the pump.

LG washer not draining triggers the OE error code (sometimes misread as 0E) and is almost always caused by a clogged drain pump filter. LG front-load washers have a dedicated pump filter access door on the lower front panel - this is one of the most accessible filter designs of any washer brand. The filter catches coins, hair ties, bobby pins, buttons, and small fabric items. LG recommends cleaning this filter monthly, but most owners discover it only when the washer stops draining. IMPORTANT: when you open the filter, 1-2 gallons of standing water will pour out. LG includes a small drain hose next to the filter cap specifically for draining this water in a controlled way. Pull out the small hose, place the end in a shallow pan, and uncap it to slowly drain the water BEFORE unscrewing the main filter cap. This LG-specific feature saves you from a flood on your laundry room floor. After draining through the small hose, unscrew the filter cap and remove debris. On LG top-loaders, the filter is less accessible - it is inside the pump housing underneath the machine.

Frequently Asked Questions

Where is the LG washer drain filter?

On front-load LG washers, the drain filter is behind a small access door on the lower front panel, usually on the right side. Open the door and you will see the filter cap and a small emergency drain hose. On top-load LG washers, the filter is inside the pump housing underneath the machine.

What is the small hose next to the LG drain filter?

This is LG's emergency drain hose - a feature specific to LG washers. It lets you slowly drain the standing water from the tub into a pan BEFORE opening the main filter cap. This prevents the 1-2 gallons of water from flooding your floor when you remove the filter. Pull it out, uncap it, and let it drain into a pan first.

LG washer OE error but filter is clean. What else?

If the filter is clean: 1) Check the drain hose for kinks (most common after filter). 2) Check the standpipe for a clog (pour a bucket of water in directly). 3) Listen for the drain pump - humming means impeller jammed by something past the filter. 4) Silent pump = motor failed ($25-50).

How often should I clean the LG drain filter?

LG recommends monthly. Every 2-3 months is practical for most households. If you have pets or family members with long hair, monthly is better. Always check pockets before washing - coins and small items are the #1 cause of filter clogs and pump jams.
