your water inlet solenoid's may have packed up unusual for both or may be pressure switch fouled up abit.remove top after you disconnected from main's power.as you are looking down from front,look for a circulair electrical conponant with a rubber tube (about 8mm round) remove pipe from componant & blow down this tube to clear any residue's that may be blocking the other end,once you can pass air through freely replace tube to componant to see if this has cured your problem,if not it will be your solenoid's.best of luck
