Amana Dishwasher not cleaning
If your Amana dishwasher is not cleaning, or your dishwasher is not cleaning dishes and leaving dishes dirty after the cycle, start with the most common cause: a restricted or failed water inlet valve. When the water inlet valve does not let in enough water, the dishwasher cannot wash properly. Next, check for simple loading issues, since crowded dishes can block spray patterns and leave food behind. Water temperature matters too. Your dishwasher needs about 120°F water to clean well, so low incoming hot water can cause dishes still dirty after dishwasher cycle complaints. After that, inspect the center wash arm support, center wash arm assembly, and lower wash arm assembly. If the support is damaged, not lined up with the water supply nozzle, or the wash arm holes are clogged with debris, water will not reach the dishes the way it should. On many Amana models, these are the key parts behind a dishwasher not washing properly. Enter your model number on RepairClinic.com to find the exact Amana water inlet valve, center wash arm support, center wash arm assembly, or lower wash arm assembly that fits your dishwasher.
01 - Amana Dishwasher Water Inlet Valve
The water inlet valve opens to allow water to enter the dishwasher. If the valve is clogged or defective, the dishwasher won’t get enough water to clean dishes properly. If the water inlet valve is clogged, replace it. Do not attempt to clean the water inlet valve—cleaning the valve could make it more likely to fail.

02 - Improper loading
Improper loading will keep the water from cleaning the dishes. Make sure you are leaving enough space between the dishes.

03 - Improper water supply temperature
The water may not be hot enough. The recommended water supply temperature for a dishwasher to clean properly is 120 degrees Fahrenheit (49 degrees Celsius). If your hot water temperature is lower for safety reasons, try using a longer cycle that heats the water.

04 - Amana Dishwasher Center Wash Arm Support
The center wash arm is attached to a support that is normally attached to the underside of the upper dishrack. Water flows through the support to the arm which circulates the water to the dishes in the upper rack. If the support is damaged or obstructed water may not flow properly. Inspect the support for any damage or obstruction and replace if necessary. In addition, make sure that the support is mating properly with the water supply nozzle.

05 - Amana Dishwasher Center Wash Arm Assembly
The center wash arm circulates water to the dishes in the upper rack. If water can’t flow properly through the center wash arm, the dishes in the upper rack won’t be cleaned properly. Over time, food particles can get trapped in the tiny holes in the wash arm. If your dishes are coming out dirty, the wash arm might be clogged. To unclog the center wash arm, remove the wash arm and dislodge any debris from the holes. If the wash arm is extremely clogged, replace it. In addition, make sure that the center wash arm assembly is mating properly with the water supply nozzle.

06 - Amana Dishwasher Lower Wash Arm Assembly
The lower wash arm circulates water to the dishes in the lower rack. If water can’t flow properly through the lower wash arm, the dishes in the lower rack won’t be cleaned properly. Over time, food particles can get trapped in the tiny holes in the wash arm. If your dishes are coming out dirty, the wash arm might be clogged. To unclog the lower wash arm, remove the wash arm and dislodge any debris from the holes. If the wash arm is extremely clogged, replace it.
