Dishwasher Hookup


Bought a new dishwasher for my house and the sales person at the appliance store told me that it is now required by code to have a plug and outlet hookup instead of hardwiring the dishwasher. Is this true? If so, do I need to install GFCI outlet under the sink for the dishwasher?

Re: Dishwasher Hookup


If you’re doing it yourself you can do whatever you want. I don’t like to hardwire them. I can’t remember ever seeing a gfci buried inside a cabinet.

Re: Dishwasher Hookup


Must have a disconnect means since 2014, normally a receptacle in the sink cabinet.

2017 NEC 210.8(D) requires GFI for dishwashers.

Re: Dishwasher Hookup


Some of the inspectors around here are requiring the gfci to not be buried in the cabinet as it is "not accessible ".

Re: Dishwasher Hookup


i don`t know if its everywhere , but in south florida, all appliances in the kitchen have to have a plug.
basically , that way , a home owner can replace their own appliance , without having to call a service guy. they can just unplug it , buy and plug in the new one .
never was asked about the receptacle inside the cabinet being g.f.i.
don`t think so , i mean the fridge isn't dishwasher isn't ,

Re: Dishwasher Hookup


Here do a duplex mounted in the wall under the sink. One is switched for GD and the other is always hot for the DW to plug in. Both served by a gfci breaker.

Re: Dishwasher Hookup


I usually run emt up into the sink cabinet to a square box with a switch and a short whip of MC going out to the dishwasher.

I'm not completely sold on this method, the switch might be kind of pointless but if the dishwasher is malfunctioning and you need to shut it fast, it works. Also, I've seen lots of rodent damage on cords and romex cables to dishwashers in the past.


I've never been required to protect dishwasher with gfci here by inspectors but they let a lot slide in this little town.

Re: Dishwasher Hookup


if your adding a receptacle for the dishwasher it will need to be GFCI AND AFCI protected

Not necessarily. A lot of jurisdictions are still using older code cycles that don't even require GFCI let alone AFCI on a dishwasher. It doesn't mean you shouldn't protect it if you feel like it's important though.

GFCI protection is for receptacles only

AFCI protection is for the entire circuit.

I know you know this but gfci is not only for the receptacle but it is required for the dishwasher even if it is direct wired. I think that is what Manchester meant

We just change the breaker to gfci and install a lockout, makes for a much neater install.

By definition, the connection is still made at an outlet on a direct wire install.

I believe if you're adding any single pole 15 or 20 amp circuit under the last few NEC code cycles they have to be AFCI protected. If it is an existing circuit you do not have to add the AFCI only the GFCI.

Local amendments may change the requirements.
