Re: Residential Dishwashers
Mine is a receptacle. I don't know if they all are. I think the electrician may had to provide the cord and connect it to the dishwasher. If that is the case, the electrician would have had the option to hardwire it.
A cord and plug connected unit has a disconnect at the unit by virtue of being able to unplug it.
If it's hardwired, you may have to provide a breaker lock or something along that line.

Re: Residential Dishwashers
I have seen both.
I prefer to cord and plug connect the dishwasher this meets the requirement for a disconnect and makes replacement easier.

Re: Residential Dishwashers
In every house I've owned or rented, they have been hard-wired.

Re: Residential Dishwashers
In my area, it is standard practice to hardwire them. I have never seen them cord and plug connected.

Re: Residential Dishwashers
See section 422.16(B)(2). This allows the use of a flexible cord and receptacle, otherwise "hard-wiring" would be required.
If "hard-wired", a disoconnecting means is required. Generally we permit a lock-out on the branch circuit breaker or a switch at the dishwasher location. Most dishwashers can't comply with all the specifications of 422.34

Re: Residential Dishwashers
I like the wall switch. When customer calls and says "My dishwasher doesn't work" It can generate a service call. We go thru the list--did you check all the breakers, any GFIs tripped, is there a counter switch in the 'off' position? Yes, no, no. We go out and, sure enough, there is a switch in the off position. "Anything else I can do for you today?" Write a check for $XX.XX. Thank-you!!

Re: Residential Dishwashers
Hard wire and 50 cent breaker lock or cord ,receptacle,box,plate cover.Only reason for cord and receptacle is if dw is not there on the trim so we can pass final.Now the real question,will the repairman use the lock out ?

Re: Residential Dishwashers
I do lockout all the time. Here in Iowa I've seen both ways as a wiring method.

Re: Residential Dishwashers
I have never seen any disconnect for a dishwasher located near the dishwasher or on the breaker panel in the house. The only thing I have ever seen is the dishwasher to be on a circuit with other devices on the same circuit tied to a breaker on the breaker panel of the house. A 15amp breaker can serviec a dishwashser and other items in the house and that is how I have seen it usually.

Re: Residential Dishwashers
I have an easy way to lock out my (hard wired) dishwasher. I just have to turn on the toaster and the coffee pot, and the breaker will trip.

Re: Residential Dishwashers
1. I always pull a 3-wire homerun for the disposal/dishwasher.
2. Generally, with many of the floorplans I wire, the DW is right next to the kitchen sink. In those situations, I have a duplex in the cabinet, one circuit for each, both cord connected.
3. If the DW is away from the sink, I hardwire the dishwasher, pulling 2-wire out from the disposal's box.
Edit to add: Lately my hardwire DW's have been causing me angst, since the contractor has stopped getting appliances in until the spec goes under contract. Then I have to slide in and cut in a receptacle to clear inspection. I guess I'll just start C&P connecting them all.

Re: Residential Dishwashers
Unlike George who goes both ways I am strictly heterocordandplugconnected. Just seems to be more convenient for my installations. I also find that the dishes are cleaner.

Re: Residential Dishwashers
I put the switches for my direct wired d.w.'s in the cabinet under the sink where some of you guy's put a receptacle for the same purpose. Less chance of inadvertant disconection resulting in service call backs especially since I label the switchplate in big letters.
