Rinse aid is not dispensed; poor drying and spotting on glassware with E11 displayed.

Safety first: Use gloves and eye protection when handling rinse aid chemicals.

Steps to resolve:

• Check rinse aid level: Confirm the Champion-compatible rinse aid reservoir is filled and the pickup tube is properly inserted.
• Inspect tubing: Examine the suction and discharge tubes for kinks, blockages, or air leaks. Replace any brittle or discolored tubing.
• Prime the pump: Use the prime function or manually run several cycles to draw rinse aid through the line. Watch for air bubbles and continue until a steady flow is observed.
• Test rinse aid pump: During the rinse phase, listen for pump operation and measure voltage at the pump. If voltage is present but the pump does not run, replace the rinse aid pump.
• Check injector fitting: Remove and clean the rinse aid injection fitting where it enters the rinse line or tank. Scale buildup can prevent proper dosing.

When to call a technician: If the control board does not energize the pump or if an external chemical controller is used, professional diagnosis is recommended.
