Installing a dishwasher? Is there an outlet?


My wife is convinced our dishwasher is going to fail soon and wants a new one. I think she just wants a SS DW to go with our new SS refrigerator.

Anyhow.... the stores won't install one unless it is plugged in. If it is hardwired they require an electrician. I pulled the kickplate off and see a piece of romex coming off it, going across the bottom and up the back. I can't see where it goes after that. The house is 12 years old. Could it be hardwired, or is there an outlet on the back? The romex suggests hardwiring. but I've seen plugs on romex, so it doesn't prove anything.

I installed one myself 15 years ago at my old house when the store refused to do it because the garbage disposal and the DW shared a circuit. But I was 15 years younger then. Of course I had to reinstall the fridges water line myself because it leaked after the "installer" did it...

That would be hard wired.

Turn the power off, disconnect the Romex from the DW, route the Romex into the sink base cabinet and install a surface mounted box and receptacle.

Turns out Lowes will do hardwires, so I am all set; though it might be best to just install an outlet and be done with it. Thanks.

There's really no need to install an outlet for a DW plug. Hardwired is the norm and quite simple. Besides, you would have to buy an approved cord kit for the DW.

Hard wired no longer meets code. A DW requires a disconnect at the appliance.

Any commercial UL cord and molded cord cap will suffice.

Meeting current code is probably not an issue with a replacement DW if the previous one was hardwired. It is easy to presume that the hardwired unit met code at the time, so hardwiring the replacement would be allowed via grandfathering. But a unit plugged into a receptacle under the sink is so much easier to install that hardwiring is just dumb even if it is allowed.

That was my thinking, but you are correct in advising it should be at least to min code even if it were to be grandfathered. It may be more involved than just bending the romex to under the sink (passing through the cabinet wall) and if its not a currently dedicated circuit.

Install an outlet under the sink as previously mentioned. Easier for service and troubleshooting . Easy to replace. IN an emergency you can just pull the plug. Hardwired always has limitations especially if the person who hard wired it didn't leave enough slack for service And many do . Especially delivery men who want to throw it it and get to the next one. Put the outlet in and use a cord on the dishwasher. You will be happy some year.

Re: Installing a dishwasher? Is there an outlet?


With a hard wired dishwasher one only needs to have the old hard wire replaced with an appliance cord that plugs into a receptacle under the sink, same as with a garbage disposal. What is important is that there is ready access to the plug so if the appliance has a short it can be quickly unplugged before you have a fire.

Good idea to replace the drain line while you are at it with the old dishwasher removed.
