What to do if the LG Dishwasher displays a DRAIN ERROR?
- KkgibbsJul 25, 2025
If your LG Dishwasher displays a DRAIN ERROR, you can try the following: First, clean the filter assembly. Next, remove any kinks or blockages in the drain. You may also need to clean the air gap or the drain motor. Ensure the wire is properly connected. Additionally, remove the knock out plug. If these steps don't resolve the issue, the drain motor or pump casing assembly might need repair or replacement, or the controller might need replacing.
