Asko Dishwasher not cleaning
If your Asko dishwasher is not cleaning, start with the basics that most often cause poor wash performance. A clogged or failing water inlet valve is the most likely culprit, because if the dishwasher is not filling with enough water, it cannot wash properly and you end up with dishes still dirty after the dishwasher cycle. Next, check for improper loading, since packed-in dishes can block spray patterns and leave your Asko dishwasher not cleaning dishes evenly. Water temperature matters too. If the incoming water is below 120°F, the machine may struggle to break down soil. After that, inspect the center wash arm support, center wash arm assembly, and lower wash arm assembly. If a spray arm is clogged, damaged, or not lining up with the water supply nozzle, water will not reach the dishes the way it should. This is a common reason for a dishwasher leaving dishes dirty, especially on one rack. Enter your model number on RepairClinic.com to find the exact Asko water inlet valve, center wash arm support, center wash arm assembly, lower wash arm assembly, or other replacement part that fits your specific dishwasher.
01 - Asko 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 - Asko 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 - Asko 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 - Asko 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.
