It seems there is not enough pressure to turn the spray arms. Could it be this inlt valve?
ANSWER Hello Dan. Yes, if the water level is not filling the dishwasher up to the proper level, you may have a bad inlet valve on the unit. You can check and see if the water level fills to the heater. If not, you will need to replace the water valve in the unit.
