If your place has a dishwasher currently the installation is simple. It's taken me two days to install my new Bosch. I needed to run electrical and install the sink & disposal. The electrical should install on a GFCI circuit within 4" of the base. The power and water lines can not touch so they run along left. I cut pass through holes with 2" of the back. The water & drain line should be higher then 20" to create a drip loop. In the event of the drip loop allows the line to hang so it's not resting in a puddle.
Applied some polyurethane to underside of the butcher block and some HAVC foil tape to protect from moisture. The foil strip should go above the door opening. I'm running the hot water line and drain throught the sink cabinet. The dishwasher electrical outlet is GFCI protected.

Level the dishwasher, connect the lines, power on (test for leaks) and attach to counter!
