LG Dishwasher OE Error Code

Not draining on LG dishwashers.

Moderate DIY

The pump didn't get all the water out of the tub. A food-clogged filter or a kinked or blocked drain hose is the most common reason, and a badly installed drain hose can do it too.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG OE

Clean the filter
Give the water about 30 minutes to cool after a cycle, then unplug the dishwasher. Twist the filter assembly out of the tub floor, scrub it under running water with a soft brush and lock it back in. LG suggests doing this every week or two.
Check the drain hose
LG says to close the water shutoff valve before you handle the drain hose. Under the sink, look for kinks, crushed spots or clogs. Where the hose connects at the sink or disposer, it should be at least 12 in (30 cm) off the floor; any lower and sink water and odors can back up into the dishwasher.
Clear the sink drain or disposer
If the hose runs into a garbage disposer, run the disposer to clear out food. With a newly installed disposer, check that the knockout plug in its dishwasher inlet was knocked out.
Force a drain
Plug the dishwasher back in, turn it on and hold Start for about three seconds. The pump should run for two to three minutes. If water is still sitting above the filter afterward, stop there.

When to call a technician

Water still pooling over the filter after cleaning it and checking the hose means the drain pump probably needs service.
