hi,whats your model number ,will the water keep running if you unplug the machine? or does it stop?
or does it just keep filling to the high setting if you have it set on low or med?
hi its either a faulty stuck water valve,if it keeps running with the power cord out,its 100% the valve
or a pressure switch or pressure switch hose,if the pressure switch hose has a hole it will keep filling or sometimes not likely, but a pressure switch itself
