This part is the replacement inlet valve for your dishwasher. It is approximately 4-1/2 inches by 3-1/2 inches. The water inlet valve in your dishwasher connects to the water source and solenoid wires, and ensures the tub has the right amount of water entering it. If your dishwasher continues to fill after it is full, or if it fills slowly, you may need to replace this valve. Another indication that your valve is damaged and will need to be replaced, is if you notice it is leaking when the dishwasher fills up. Before you begin this repair, be sure to disconnect the water and power sources from your washer. This part is sold individually and is an authentic OEM part.
