My dishwasher has been making noise of late and not cleaning well. Last night I took the filter off and cleaned it out. Has water flow. Put it back in and no change. I bypassed the door switch to watch what's going on. It fills fine and pumps the water down fine. When wash cycle starts it is loud and the bottom arms spray only about a foot high. Arms rotate about a quarter turn and stops. Then will repeat that every few seconds. Wondering could this just be the circ motor? Or do I need to get the whole motor and pump assembly which is like $225..
