If you are sure that water pressure is ok to the machine and that water inlet valve filters are clear, you may find that the water inlet valve(s) have failed. This is not an uncommon problem with F&P machines..Particularly the cold valve! Replace the valve and all should be ok... DO NOT exchange the hot valve for the cold one as they are different!! I assume that the rest of the machine is functioning normally.....The two screws at thr rear of the facia will expose the valves...red and blue wires indicate the temp.....Good luck.....Nomess
