This small check ball sits inside the dishwasher's drain pump or water inlet valve and acts as a one-way valve to prevent water from flowing backward through the system. It ensures water moves in the correct direction during wash and drain cycles. Replace this part if you notice water draining back into the tub after a cycle completes, the dishwasher isn't draining properly, or water is leaking from the pump area.
