I am waiting for the electrician or someone like him. He should be here this afternoon. The plan is to make the hole in the floor large enough to drop the junction box, then run the cable up to the new dishwasher.
Note the water damage on the floor in the second picture. I came home from one of my numerous Phoenix trips and saw water streaks on the wall downstairs in the finished basement. The Bosch dishwasher had sprung a leak, and it was replaced with the Kitchenaid that is now itself being replaced.
