I was able to diagnose the problem by watching AppliancePart pros repair videos to see how to disassemble the underside components of my dishwasher. After taking off the sump I noticed there was a small hole that was causing my leak. The replacement part was able to be delivered in 2 days and reassembly was made easy with the associated videos. I believe the hardest part of this repair was remembering where all the screws attaching the dishwasher to the underside of the cabinet are and wiggling the dishwasher free. One key point that isn't explained in the videos, always tilt your dishwasher backwards (away from the door) otherwise any left over water in the sump or lines will flood back into the dishwasher and likely come out of the door when you stand it back up again.
