KitchenAid Dishwasher takes too long
If your KitchenAid dishwasher takes too long, the issue is often tied to weak water movement rather than the timer itself. A damaged wash impeller is the most likely cause, since this small blade helps push water through the wash arm system. If it is worn, broken, or missing fins, your dishwasher may not wash properly and can stretch the cycle while dishes still come out dirty. Next, check the filter assembly, filter, screen filter, and strainer in the sump. When these parts clog with food debris, water flow drops and a KitchenAid dishwasher cycle too long problem often shows up along with poor cleaning. If those parts are clean and intact, the circulation pump is another common cause. A failing pump may hum, stay quiet after the dishwasher fills, or struggle to move water through the spray arms. Depending on your model, you may be able to replace the wash impeller by itself, or you may need the full pump and motor assembly.

01 - KitchenAid Dishwasher Wash Impeller
The wash impeller is a small plastic blade that forces water up through the wash arms. If the impeller is broken or is missing some of its fins, it might not generate enough pressure to force the water up through the wash arms. On most models, you can replace the wash impeller independently of the pump and motor assembly. Search for your model number to determine if your impeller is replaceable. If the impeller cannot be replaced separately, you will have to replace the entire pump and motor assembly.

Highly Likely
06 - KitchenAid Dishwasher Circulation Pump
The circulation pump uses a motor and impeller to force water up through the wash arms. If the circulation pump is defective, the dishes won’t be cleaned properly. If the motor isn’t making any noise or is just making a humming sound after the dishwasher has filled, the motor may be burned out. First, ensure that power is getting to the motor. Second, to ensure that the impeller can turn, check the pump housing for debris. If power is getting to the motor and the pump is clear of debris, the motor might need to be replaced. Be aware that the circulation pump may be challenging to replace, although many do-it-yourselfers ha...
