LG dishwasher Error Code OE
Drain error
Common Causes
- 1Clogged filter
- 2Kinked hose
Step-by-Step Troubleshooting
- 1
Remove the bottom rack and clean the mesh filter assembly at the bottom of the tub — twist the cylindrical filter counterclockwise to remove it
- 2
Inspect and clean the flat fine-mesh filter underneath for food debris, broken glass, or grease accumulation
- 3
Check the drain hose connection at the garbage disposal or sink drain tailpiece — the knockout plug inside a new disposal must be removed for dishwasher drainage
- 4
Verify the drain hose has a high loop (mounted high under the counter) or an air gap fitting — without this, dirty water can siphon back into the dishwasher
- 5
If the drain pump hums but water does not drain, debris may be blocking the pump impeller — access from under the unit
Pro Diagnostic Tip
The most commonly overlooked cause of OE on newly installed LG dishwashers is the garbage disposal knockout plug. When a new disposal is installed, the dishwasher drain port has a plastic plug that must be knocked out with a screwdriver and hammer. Forgetting this creates a 100% blockage.
