you will need to t off from the hot water line to the washer. Use flexible hosing. Then you need to exit the water into the garbage disp, if you have one there is a hookup available for you, if no disp, then hook up to the drain pipe for exiting water. Then of course you need power. Air vent is sometimes not necessary. I would get you a good plumber for all this work. The last thing you want under the cabinets and out of the way is a steady leak.
