Hello Glen. If you can stop the water from entering the machine by turning off the timer or unplugging the unit, you will need to look for a bad pressure hose or replace the pressure switch. If the only way to shut off the water is at the shut off for the water hoses, you will need to replace the water valve in the unit.
