Mike R for Model Number GSD6200G00BB I am trying to figure out why the center spray arm is not spinning. It's not jammed up because I can freely spin it. The top one spins, (I can only check it by jerking open the door and looking quickly while it's running). If I set the middle one perpendicular to the front door, then run it for 5 seconds, then open it; the middle spray arm has turned about 30 degrees and that's it. Is there a internal mechanism that turns the spray arm or is it just a natural torque due to the angle of the exit holes? Also is it possible for a pump not to be performing up to full pressure, thus not pushing hard enough on the spray bar? Thanks, Mike R
Answer Hello Mike. The water force is driven by the motor and impeller. If the impeller is broke or clogged, you will recieve very little water pressure. Here is the part number for the impeller kit.
