User Suggested Solutions

Check and clean the drain filter. Open the dishwasher door, remove the lower dish rack, and take out the drain filter. Rinse it under running water to remove debris and reassemble.
Inspect and clear the drain hose. Disconnect the hose from the dishwasher and the sink, and check for any blockages or kinks. Use a long brush or a straightened coat hanger to remove any clogs.
Test the drain pump for functionality. If the pump is not working, it may need to be replaced. Disconnect power, remove the lower spray arm, and access the pump. Check for obstructions and test the pump with a multimeter.
