I have a Kenmore Elite HE3 washer, got it from a friend but it's more than 10 years old already I thin. recently, I've noticed a new problem. After the wash cycle is done, water keeps running into the machine from the detergent area. When I turn off the water supply to the washer it stops. But as soon as I turn the water back on it starts running again. The washer tub itself is not overfilling. I am thinking it might be the water dispenser valve. Does this sound like a problem with the valve? What else could it be?
