Waste King Dishwasher not draining
If your Waste King dishwasher is not draining and you’re seeing standing water in the tub, start with the most common cause: clogged sump filters. A blocked course filter or fine filter can restrict water flow and lead to a dishwasher clogged drain problem. If the filters are clear, the next likely issue is the drain pump not working. A failed drain pump motor, a damaged drain impeller, or a clogged or faulty drain valve can all keep dishwasher water from draining through the drain hose. On some models, a bad drain solenoid kit can also prevent the drain valve from opening. If those parts check out, the control board may not be sending power to the drain pump. This kind of Waste King dishwasher not draining issue is usually straightforward to track down if you inspect the filter, test the drain pump motor for continuity, and check for debris or damage in the drain path. Enter your model number on RepairClinic.com to find the exact Waste King replacement part for your dishwasher, whether you need a sump filter, drain pump, control board, drain impeller, drain solenoid kit, or drain valve.
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 - Waste King 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 - Waste King 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 - Waste King 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 - Waste King 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 - Waste King 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.
