If your Haier dishwasher is not draining and you are left with standing water at the bottom of the tub, start with the most common cause: clogged sump filters. A blocked coarse filter or fine filter in the sump can restrict water flow and lead to a dishwasher clogged drain problem. If the filters are clear, the next part to check is the drain pump. A failed pump motor or damaged impeller can keep the dishwasher water not draining through the drain hose. After that, look at the control board, since a bad board may not send power to the drain pump at all. Less common but still important causes include a broken drain impeller, a failed drain solenoid kit that will not open the drain valve, or a drain valve clogged with debris or stuck closed. Whether your Haier dishwasher is not draining completely or the drain pump is not working, RepairClinic.com can help you track down the exact issue and the right replacement part. Enter your model number to find the exact sump filter, drain pump, control board, drain impeller, drain solenoid kit, or drain valve that fits your specific 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 - Haier 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.

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.
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.
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.
