The dishwasher fills and heats but will not drain at the end of the cycle; no error code is displayed.

Safety first: Turn off power and allow water to cool before working in the sump.

Improving drainage:

• Clean strainers and scrap baskets: Remove and thoroughly clean all Champion tank strainers and scrap baskets.
• Inspect drain hose routing: Ensure the drain hose has proper slope with no low spots that trap water. Correct any sags or kinks.
• Flush drain line: Disconnect the hose and flush with hot water to remove grease and debris.
• Check pump performance: Listen to the drain pump; if it sounds weak or labored, the pump may be failing and should be replaced.

When to call a technician: If drainage remains slow despite clear lines, a professional should test pump output and electrical supply.
