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

Safety first: Disconnect power before reaching into the sump or removing hoses.

• Clean filters: Remove and thoroughly clean the coarse and fine filters at the bottom of the tub.
• Check for debris: Look into the drain opening for food particles, labels, or glass and remove carefully.
• Inspect drain hose: Detach from the sink/disposal and flush with hot water. Ensure there are no kinks.
• Test drain pump: During a drain cycle, listen for pump operation. If silent or just humming, the drain pump may be blocked or failed and should be inspected and replaced if necessary.
