Asko Dishwasher not draining

If your Asko dishwasher is not draining, start with the most common cause: clogged sump filters. A blocked coarse filter, fine filter, or sump filter can restrict water flow and leave you with dishwasher standing water at the bottom of the tub. If the filters are clear, the next likely problem is the drain pump. A failed pump motor, bad impeller, or a dishwasher drain pump not working can keep water from moving through the drain hose. After that, check the control board, since it powers the drain pump and can cause a dishwasher not draining even when other parts look fine. Less common causes include a broken drain impeller, a failed drain solenoid kit that won’t open the drain valve, or a clogged or defective drain valve creating a dishwasher clogged drain condition. For an Asko dishwasher with dishwasher water not draining, RepairClinic.com can help you match the symptom to the right part fast. Enter your model number to find the exact Asko replacement part for your machine, whether you need a drain pump, control board, drain impeller, drain solenoid kit, drain valve, or replacement filters.

01 - Clogged Sump Filters

The sump assembly, located at the bottom of the dishwasher tub, contains the pump motor or motors to both circulate and drain the water. There are usually two filters in this assembly to strain food particles: a course filter and a fine filter. If the filters are clogged, the unit will get low water flow and poor washability. To clean filters, remove them from the sump and wash them with soap, warm water, and brush. If the filters are damaged, they should be replaced.

02 - Asko Dishwasher Drain Pump

The drain pump uses an impeller to force water through the drain hose. If the drain pump motor is not working, the dishwasher won’t drain. To determine if the drain pump is defective, check the pump motor for continuity using a multimeter. If the motor does not have continuity, or if is getting power but won’t run, replace the drain pump. Drain pumps are not repairable—if the drain pump is defective, you must replace it.

03 - Asko Dishwasher Control Board

A dishwasher's control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the drain pump, preventing it from drawing the water out of the tank and forcing it through the drain hose to the garbage disposal or sink drain pipe.

04 - Asko Dishwasher Drain Impeller

The drain impeller pushes water through the drain hose and into the garbage disposer or drain line. If the impeller is broken, replace it.

05 - Asko Dishwasher Drain Solenoid Kit

The drain solenoid opens the drain valve to allow the water to exit the dishwasher. If the drain solenoid fails the valve will not open causing the dishwasher not to drain.

06 - Asko Dishwasher Drain Valve

Over time, the drain valve can get clogged with debris. To ensure that water can flow through the drain valve, clean out the valve. If the drain valve is clear of debris but it still won’t actuate, replace it. Drain valves are not repairable—if the drain valve is defective, you must replace it.
