Champion dishwasher we have a champion freestanding dishwasher at my church. after the cycle is completed, the pressure guage behind the washer still shows 25-30 and it contnues to spray water. not forced by the motor, but more like a stuck open fill valve. if i turn off the water and run it, then turn the water back on, the valve is closed and does not let water freely in. butif i run it with the water on, it will continue to spray in freely after the cycle light goes out and you open the door.

I recently replaced the water seals, V-packing & all six check valves in a CW-3504-4MGH pump on a MiTM 3504 pressure washer that had very low pressure. Usually this would fix most pressure problems on most machines, but in this case it had little to no effect. I suspect that the unloaded is the culprit in this case, but since I have had little experience in repairing unloaders (let alone adjusting them). I would appreciate feedback from anyone that has experience in this area. Thanks
