We have a 75 lb. boxer/lab mix that decided to help empty the dishwasher. We found him on the couch with the top dish rack hooked on his collar. Both adjusters were destroyed. I ordered the parts from AppliancePartsPros using standard delivery. I was surprised to find the parts were delivered 2 days after I ordered! It was a quick job to replace the adjusters and the dishwasher is back in service awaiting more "help" from our dog.
I've ordered various parts from AppliancePArtsPros several times over the year. Their delivery always meets or often exceeds their estimated dates and their prices are reasonable. I've also found their how-to videos extemely heloful.
