I made a video of the noise, sent it to Appliance Parts Pros and asked them if I might need a new washer pump for my Whirlpool Duet washer. I went online and ordered the part by entering my Serial #. There was double verification that it was the correct part. I watched their "How To Install" video on the same page. It came the next day and I installed the new part. It works perfectly. Felt accomplished as I am a 64-year-old granny.
