Maybe if you do a video to show what's happening, it would help. I recently got two Whirlpool washers with pump issues. Both machines have a brush-type lint filter rather than the self-cleaning one. On one pump, the valve that's actuated by the wig wag assembly was stuck and on the other one, the lower impeller was broken so it emptied the tub very slowly and the recirculation (for the lint filter) didn't work.
