Dishwasher does not drain; water remains at the bottom of the tub after the cycle completes.

Safety first: Turn off power before working with standing water inside the appliance.

Step-by-step checks:

• Clean filters: Remove the lower rack and filters. Clear any food debris and rinse under hot water.
• Check sump area: Look for broken glass, labels, or food blocking the drain intake.
• Inspect drain hose: Under the sink, detach the drain hose from the disposal or drain stub and check for clogs. Flush with hot water.
• Air gap: If present, remove the air gap cap and clean out any blockage.
• Test drain pump: Run a cancel/drain cycle. If the pump does not run or only hums, it may need replacement.

Warning: Do not use chemical drain cleaners in the dishwasher; they can damage seals and plastics.
