This can be very simple to find the fault. One can replace the solenoid by a new one. If the new one does not work, then the fault is coming from the control board. Many control boards nowadays are changed by a new one. Also there are cases were the transformer supplying control boards and solenoid valves, gets faulty. Some times there are also relays in the system, which also can go faulty. The best way, is to go first for the easiest fault and proceed by elimination, to the other components. I hope you only have a fault, in the solenoid. Regards. MG.
