How to fix it
- Pull the lower rack and remove the cylindrical filter assembly; rinse it under the tap.
- Remove the chopper cover if present and clear any debris around the impeller.
- Pull the dishwasher out and inspect the drain hose for kinks; disconnect at the disposer end and check for grease clogs.
- If recently installed to a disposer, confirm the disposer's knockout plug was removed.
- If the path is clear, test the drain pump for free rotation; replace if obstructed or weak.
