Dishwasher will not drain; standing water remains in the bottom after cycle.

Safety First: Turn off power at the breaker before working near the sump. Water may be hot.

• Remove standing water: Use a cup or sponge to remove most of the water from the tub.
• Clean filters: Remove and rinse the coarse and fine filters thoroughly.
• Inspect sump: Check for debris in the sump opening that could block the pump.
• Check drain hose and disposal: Ensure the hose is not kinked. If recently installed to a disposal, verify the knockout plug was removed.
• Run a drain cycle: Restore power and run a cancel/drain. Listen for the pump. If silent or just humming, the pump may be failed.
• When to call for service: Persistent drainage issues after clearing obstructions indicate the drain pump or internal plumbing needs professional service.
