Maytag Dishwasher not draining
If your Maytag dishwasher is not draining, start with the most common cause: clogged sump filters at the bottom of the tub. A blocked coarse filter, fine filter, or screen filter can restrict water flow and leave you with dishwasher standing water or a dishwasher clogged drain. If the filters are clear, the next likely problem is the drain pump. A failed pump motor or damaged impeller can keep dishwasher water not draining at the end of the cycle. After that, check the control board, since it supplies power to the drain pump and can cause a Maytag dishwasher not draining even when the pump itself is good. Less common causes include a broken drain impeller, a failed drain solenoid kit that cannot open the drain valve, or a drain valve clogged with debris or stuck closed. Follow the symptom from simplest to more involved checks, and replace the bad part rather than guessing. Enter your model number on RepairClinic.com to find the exact Maytag sump filter, drain pump, control board, drain impeller, drain solenoid kit, drain valve, or drain hose part that fits your dishwasher.
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 - Maytag 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 - Maytag 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 - Maytag 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 - Maytag 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 - Maytag 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.
