Go to your excellent website, click on schematic photos and order. The hardest part is taking a good photo of your appliance model's Serial # and ID plate.
Tenants threw away dishwasher parts, then claimed "...dishwasher was faulty."
Bottom fridge fan was okay, but I replaced that as well. I unplugged frig from power supply (duplex). I redid all electrical connections employing PermaTex Dielectric grease. Keeps out moisture as well as making job easier for next tradesmen. I dumped all ice maker ice and began a new batch.
Entire job, two appliances was under 30 minutes. I used my Ryobi 18v battery drill to remove various screws.
It pays to keep solid appliances running. Amazing to get the parts delivered so fast!
Thanks again!
