Amana Dishwasher takes too long
If your Amana dishwasher takes too long, the problem is often tied to weak water circulation that also leaves the dishwasher not washing properly or dishes still dirty after the dishwasher cycle. The most likely cause is a damaged wash impeller, which may not push enough water through the wash arms to clean efficiently. Next, check for a clogged filter assembly, filter, screen filter, or strainer in the sump, since restricted water flow can stretch cycle times and reduce cleaning performance. If those parts are clear, the circulation pump is another common cause. A failing pump motor may hum, run weakly, or stop moving water the way it should. On some models, the wash impeller can be replaced on its own, but others require replacing the full pump and motor assembly. Start with the simple checks first by cleaning the sump filter and screen filter, then inspect the wash impeller and circulation pump if the dishwasher cycle is too long or the dishwasher runs for hours. Enter your Amana dishwasher model number on RepairClinic.com to find the exact replacement part that fits your machine.
01 - Amana 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 - Amana 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...
