Recently the washer is going through the complete cycle and the middle spray arm is not spinning. The machine doesn't sound like the pump is pumping water up through the upper nozzel. (there is a distinct louder sound when the upper spray arm is receiving water. It will rarely run with the upper arm activating. I open and close the door several times in a row and it will kick in. I have opened the door after it kicks in and when I close the door, it sometimes quits again. It is very intermittent. I don't think it is the door switch (everything else works fine) unless there are two sperate switches. (not likely) Is there a relay or switch which controls the pump motor to move to a higher volume, or is there a seperate pump for the upper sprayer arm? Or, is there a winding starter etc for a single moror which increases the rpms of the pump motor to increase the velocity and volume of water up and into the upper sprayer arm?
