LG Dishwasher OE code: Drain error
The dishwasher could not pump the water out. Standing water is often left in the bottom of the tub.
Most common causes
- Clogged filter at the bottom of the tub
- Kinked or pinched drain hose behind the dishwasher
- Clogged sink air gap or blocked garbage disposal inlet
- Installation issue on a new unit (disposal knockout plug left in, hose routed wrong)
- Failed drain pump
What you can safely check yourself
- Remove and rinse the filter at the bottom of the tub
- Check the drain hose under the sink for kinks
- Clean out the sink air gap if you have one, and run the garbage disposal
- If the dishwasher and disposal are new, confirm the installer removed the disposal knockout plug
- Use Cancel & Drain (or restart the cycle) to force a drain
Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.
