The washer would overfill intermittenly.

I replaced the water valve that the hot and cold hoses hook up to, and the pressure switch which regulates the amount of water that fills the tub. Both parts are located in the top plastic section of the washer where the controls are. The repair was easy, just a matter of taking out two screws in the back, lifting off the control face, unscrewing the water hoses, unscrewing each part, disconnecting and reconnecting the electrical plugs, and reassembling. No problems since.
