What Does OE Mean?
LG dishwasher error OE means water isn't draining properly. This is typically caused by a clogged drain hose, blocked filter, or garbage disposal connection issue.
Common Causes
Clogged Drain Hose
Food particles and grease can build up in the drain hose over time.
Dirty Filter
The bottom filter assembly is clogged with food debris.
Disposal Knockout
If connected to garbage disposal, the knockout plug may not have been removed.
Drain Pump Failure
The drain pump motor may have failed and needs replacement.
Step-by-Step Fix
Clean the filter
Remove the bottom rack and twist the cylindrical filter counter-clockwise. Rinse it under hot water and scrub with a soft brush.
Check the drain hose
Pull the dishwasher out slightly and inspect the drain hose for kinks or clogs. Disconnect and flush with water if needed.
Check garbage disposal connection
If your dishwasher drains through a garbage disposal, run the disposal to clear any blockage. For new installations, make sure the knockout plug was removed.
Test the drain pump
If the above steps don't work, the drain pump may need replacement. You can hear if it's running during a drain cycle — silence means it may have failed.
