Water Inlet Valve - Part # 3282910 Mfg Part # 5221DD1001F

Water Inlet Valve

RepairClinic Item # 3282910

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.
