When the machine is filling with water, turn the power off at the wall. If the water continues to flow in with the power off, you have a faulty inlet valve. Change the water inlet valve. Put in a new one. If the water stops when you turn off the power & starts again when you switch power back on, then the valve will be ok and you will find a problem with the pressure switch or pressure tube which goes from the side of the plastic outer bowl up to the pressure switch in the panel.
