To understand what they are talking about for the dishwasher. There is an electrical connection under the bottom front of the machine. Quite often an outlet is provided somewhere behind it. What they are saying is to run what is called a Wip connection in which a plug is at one end and the wires then connect to the machine on the other.
Also in many cases the machine is direct wired. Meaning there is no plug at all. The washer is directly wired to the wire that is supposed to be inside the cabinet opening that accepts the machine. If its there, then it is just a matter of re-connecting the machine to it.
Yeah, Sandy I found out when I had my kitchen put in a few years ago -- seems every thing needs its own outlet - It's a pain now but it is for the best.
