Dishwasher runs but does not drain; water remains in the bottom after cycle completes.

Safety first: Turn off power and water. Be prepared for water spillage.

• Clean filter: Remove the lower rack and twist out the filter. Rinse thoroughly under hot water.
• Inspect sump: Look into the sump for food, glass, or labels blocking the drain path. Remove any debris.
• Check air gap and sink connection: Clean the air gap and ensure the garbage disposal or sink inlet is clear.
• Inspect drain hose: Check for kinks. Disconnect and flush the hose to clear clogs.
• Test drain pump: Start a drain cycle and listen. If the pump hums but does not move water, or is silent, replace the drain pump assembly.
