Samsung Dishwasher not draining
If your Samsung dishwasher is not draining and you’re left with standing water in the tub, start with the most common cause: clogged sump filters. A blocked coarse filter, fine filter, screen filter, or strainer in the sump can restrict water flow and lead to a dishwasher clogged drain condition. If the filters are clear, the next likely problem is the drain pump. A failed pump motor or damaged drain impeller can keep the dishwasher water from draining through the drain hose. After that, check the control board, since it sends power to the drain pump and can cause a Samsung dishwasher not draining even when the pump itself is good. Less common causes include a bad drain solenoid kit or a clogged or failed drain valve that will not open to let water out. If your dishwasher is standing water after the cycle or the drain pump is not working, these are the parts to inspect first.

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 - Samsung 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 - Samsung 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 - Samsung 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 - Samsung 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 - Samsung 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.
