This part is the replacement hot water valve for your washer. It is approximately 2-1/2 inches by 3-1/2 inches, and the valve head is approximately 1 inch in diameter. The hot water inlet valve in your washer connects to the water source and solenoid wires, and ensures the tub has the right amount of hot water entering it. If your washing machine 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 washer 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.
