LG Washer Error Code OE

Drain error. OE (E03 or E21 on some newer models) means the washer cannot drain the water from the cycle. LG lists a kinked drain hose or a clogged drain pump filter as the usual causes. Too many suds can also trigger it.

Likely causes

• Kinked or clogged drain hose
• Clogged drain pump filter
• Excess suds creating air pockets in the pump
• Frozen drain hose in a cold garage or basement
• Failed drain pump

Safe checks you can do

Safety: Unplug the washer before touching the pump filter, hoses or drum. Water left inside can be hot and heavy, so put towels down first.

1. Check behind the washer for a kinked or clogged drain hose.
2. Run a spin-only cycle and listen for the pump humming during the first 15 seconds.
3. If it hums, unplug the washer, drain the residual water through the small drain tube, and clean the drain pump filter.
4. Run a Tub Clean cycle and cut back on detergent if suds are the problem.

When to call a pro

• No humming during the spin test (the pump may have failed)
• The filter is clean and OE keeps returning
• Any time you smell burning or gas, see sparks, or would need to open a panel
