One of the most common problems with noise in an MAV washer is
something in the pump. It makes a screeching noise when in spin. Just
change the pump. Unplug the washer. Take off the front. Remove the
belt from underneath. Remove the pump's hoses and 3 3/8" bolts.
Replace with new pump. Finish by putting on belt, plug in and test.

Important: remove the finned insert from the old pump and put into the
new pump.
