Found the parts I needed on the Appliance Parts Pros website. Went to my local appliance store with the pictures from the website, and they did not agree that the replacement rack roller was what I needed. I was to return with a picture of my Dishwasher upper rack to show them. This was a 30 mile round trip, that I was going to have to do again before the parts I needed would even be ordered. Came home, went back to Appliance Parts Pros website and ordered the 2 items I needed. They arrived 2 days later (even though I only requested regular shipping) which was before I would have even been able to make the next trip to the local appliance store. The parts worked just great.
Appliance Parts Pro website was very user friendly and having pictures with each item was a big help. The Whirlpool/Maytag website did not include pictures which was very frustrating.
