My washer is almost 6 years old & in the last year it will sometimes NOT stop filling up, but the cycle will run. Water just comes out all over the place until the entire cycle is done. It seems to do this on the rinse cycle as opposed to the wash cycle. & it doesn't do all the time. Any advice of whats wrong or needs to be replaced?? If I catch it the only way to stop it is to shut off the water, then let the cycle complete.
