Top and middle arm not turning, does not appear to be clogged. turns freely by hand.
Answer Fred, Check to make sure the dishwasher is filling properly. Start the dishwasher in a cycle and let it run 3 to 5 minutes. unlatch the open the door and remove the lower rack. The water level in the front of the tub in the left hand corner should be 1/3 to 1/2 way up the float cover WD12X10051 If there's not enough water in the tub, the pump can't produce the pressure to rotate the arms, and wash properly. You'd want to replace the fill valve WD15X10003 if that's the case.
