Admiral Dishwasher not cleaning
If your Admiral dishwasher is not cleaning dishes, start with the most common cause: a restricted or failed water inlet valve. When the valve cannot bring in enough water, the dishwasher is not washing properly and dishes still come out dirty. Next, check for improper loading, since tightly packed dishes can block spray coverage and leave an Admiral dishwasher not cleaning the way it should. Water temperature matters too. If the incoming hot water is below 120°F, the dishwasher may struggle to remove food and grease. After that, inspect the center wash arm support, center wash arm assembly, and lower wash arm assembly. A damaged support, a clogged wash arm, or a poor connection to the water supply nozzle can keep water from circulating to both racks, causing the dishwasher to leave dishes dirty after the cycle. Clear debris from the spray arm holes if possible, but replace badly clogged or damaged parts. To get the exact water inlet valve, center wash arm support, or wash arm assembly for your specific Admiral dishwasher, enter your model number on RepairClinic.com.
01 - Admiral 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.

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 - Admiral 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 - Admiral 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 - Admiral 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.
