On the Appliance PartsPros website I was able to search for "leak" in the section for my dishwasher model. I immediately got a hit that described exactly what our machine was doing. The result included a link to the part I needed as well as a video to show how to do the repair.
I ordered the part and received it the NEXT DAY! The part fixed the problem and I had the dishwasher working that night. I was able to bring an otherwise fine dishwasher back to life and avoid an $800 replacement with a $35 part.
I would highly recommend Appliance PartsPros as your first response if you want to try and fix your appliance.
