Dishwasher is not draining; standing water remains in the bottom after the cycle completes.

Safety: Turn off power and bail out as much water as possible before accessing the pump.

• Clean filters and sump: Remove the bottom rack and filters. Clear any food debris from the sump area.
• Check air gap and sink connection: Clean the air gap (if present) and ensure the connection at the sink or disposer is not blocked.
• Inspect drain hose: Detach the hose from the sink/disposer and check for clogs or kinks. Flush with hot water.
• Test drain pump: If the pump hums but does not move water, or is silent, access and inspect the pump. Remove obstructions or replace the pump if defective.

Note: Regularly cleaning filters greatly reduces drain problems.
