If I'm replacing something as the OP stated that means I'm removing the existing one. And since he had to refer to wiring directions I'm assuming he's never done this before, disconnected the wiring not realizing there's an extra wire and now doesn't know where it goes.

Regardless of my assumptions he now has to figure it out.

Re: Need Advice On How To Wire A Dishwasher


My thoughts are it is or was a MWBC, for dishwasher and disposal.


Find the breaker that turns off the black wire you said was hot. Is it a two pole breaker or a single pole breaker.
See if that black wire is in a cable with the red, white a bare ground.


If the red and black are in the same cable, this is a multiwire branch circuit and was most likely designed to power the washer and the disposal.
They should both land on a double pole breaker. Red and Black.



If this was my house I would fix it in the panel if its not done properly now and cap the red wire in the j-box under the counter.
Mark the red as disposal or hot, cap it off and leave it in the box.
If you dishwasher stops working, you will know where the red goes.


The white serves both appliances as does the ground.
