Are you sure that the inlet valve is faulty? I had the same problem. Infact, the machine had been slowly leaking from the inlet/outlet port ( circular fitting, below water hardness selector, inside right hand side) and collecting down underneath the machine, where it had activated the leak sensor cut off valve. ( see other G795SC repair reply, by Guest ) All I had to do was dry out the water underneath. and tighten clockwise the plastic circular fitting inside the machine, and it works fine again.
