It appears I am having problem with water pressure to the top arm as it won't spin. I changed the top arm with no luck. Is this impeller assembly essentially the pump to the motor?
ANSWER Hi. As well as replacing the pump impeller part # WD19X10038, you want to make sure the rear sump is clean. Remove the cover at the rear of the inner tub. Clean all debris normally fallen in this area. The top filter plate and the inner filter plate all need to be cleaned for proper pressure. Make sure the water manifold feeding the upper spray arm is not clogged. Make sure the middle wash arm feed tunnel is fully inserted into the back of the water manifold when pushed in. If there are any leaks there it will not reach the top spray arm. Thank You.
