I guess my question is more of an electrical question, sorry: I've replaced my old dishwasher with a new one. The old one was hardwired and the new one has a plug. What do I do with the old hardwire? Do I trim it, cap it, take it off the circuit entirely? As of now it's capped and shoved behind the new one but that's probably not the right thing to do. Any advice would be great! Thanks!
