LG Washer Dryer E21 Error Code

E21 on an LG washer dryer combo is a drain pump error. The display shows it when draining the tub takes longer than expected, which can be caused by a blockage in the drain line. It is also used on LG front-load washers.

What to check

The LG help library lists these checks:

1. Look behind the washer and make sure the drain hose is not kinked.
2. Check the hose itself for blockages or built-up debris.
3. Clean the drain pump filter and remove any residue.
4. Check the water inlet valve.

For front-load washers the manual adds that if debris came out of the drain pump filter, a tub clean cycle should follow. Too many suds can also trigger the code, so use less detergent. If the code appears again, the unit may need repair service.
