Dishwasher wiring


I am replacing my old dishwasher with a new one. The new ones states to hook the black wire to black, white to white and bare to ground screw.
My problem is, the wiring in my house is red, black an white. I don't know how the old dishwasher was wired but am pretty sure the white was used for the ground wire.
Should I hook the black to black, white to ground and red to white?

Your dishwasher should be on its own circuit. If it is you could simply pull your cb panel cover and see how the wires are hooked up in your panel and that would let you know what is going on.

Do not connect as described until you know where the wires go.
How old is the house? Do you know if the cabling in your house includes a bare ground wire?
Do you know if the dishwasher is on its own circuit?
Will you direct wiring the DW to an existing cable or junction box?

Dishwasher wiring


The house was built in the 40's but the kitchen is an add-on and I am not sure of the age. The house has many issues so it is no surprise the wiring is jacked up.
The wires going into the breaker have no "red" wires but the breaker that cut the power has black, white and bare wires. Not sure how that translates to the wiring that is leading to the dishwasher or where the "red" wire is coming from ....... unless it is the "bare" wire.
Again, I think the white wire was tied to the ground on the old dishwasher.
Thanks for any suggestions and/or resolutions.

There is a possibility that a switch may be in the circuit to remove power from the DW. You used the term circuit breaker and bare wire so maybe the electrical system has been updated.
Who took out the old DW?
Since the breaker has a black wire connected, which is correct, then black would go to black and white to white. Do you have a bare ground wire in the box where you are connecting the DW? You didn't answer the questions asked either which makes it hard to give suggestions.

Most likely you use red and white for the dishwasher and black was for something else such as a sink disposer, or you use black and white for the dishwasher and red was for something else such as a sink disposer.

Measure voltage between red, white, black, and ground (all combinations of two at a time). Report the results here for us.

White should be zero volts to ground and 120 volts to red and 120 volts to black. Ground should be zero volts to white and 120 volts to red and 120 volts to black. Red to black should either be 240 volts or having both go dead when one breaker handle is turned off.

I took out the old DW but did not make not of the wiring as it "seemed" obvious.......to my dismay, the new wire coloring did not match the wiring coming from the floor.
In my breaker box, the 30amp break that cut the old DW off has a black wire going to the breaker, a white and bare wires going to the side of the panel.
I have not crawled under the house to see if the wiring was spliced or going somewhere else prior to the panel box.

They might have had a disposal at one time but don't think so. the wiring that was hooked to the DW cam through the floor in the area where the DW sits and the red and black wires were going to the wires on the DW and the white was grounded......i think.
I may have to call an electrician but just hate to do so when it is (or should be) a simple unhook and rehook type of job.

I have not seen a dishwasher that required a 30 amp breaker. What is the gauge of the wires? What is the electrical requirement of the new DW (instructions or info plate on the DW)?

Cut back on that white sheathing. I bet there is a ground in there.

You need to:
1) Test white to black and see if it goes off with the breaker.
2) If it does, use the black and white and ground for the DW.
3) Replace that 30A breaker with a 15 or 20 depending on the wire size.

To be honest, I am not really that comfortable giving advice in this case. Best bet is hire an electrician to see why this is so messed up.
