When wiring a dishwasher can you an appliance cord and an outlet underneath the sink even though the instructions in the dishwasher don't say anything about appliance cords? If hardwired, can MC/romex be used in the flexibility part, or do you need SJO cord? Is a disconnect still needed if there is an on/off button on the dishwasher?

I have found that it is easier to put power in a JB under the sink for the dishwasher and then take a piece of NM cable to under the dishwasher.
I put a switch under the sink for the DW unless the dw comes with a cord and plug and then I abandon the NM cable and put a plug in the box under the sink.
Supposedly you are not suppose to use cord and plug unless it is listed for use with the dishwasher.
The switch on the dw can be the disco if it disconnects all the power on the unit. It usually doesn't and I personally feel there should be a remote disco for it

Hardwiring with SO cord is a violation of422.16(B)(2). If so cord is used then it needs to have an attachment plug.sled said:

422.16(B)(2) does say " a flexable cord identified as suitable for the purpose in the installation instructions of the appliance manufacturer. I dont think i ever checked the instructions on a dishwasher to see if i could use a cord and plug. Ive always done it though. I dont see a problem but i contact the manufactuer to be sure.
yes. the disconnect is for servicing the appliance. the on/off button will not accomplish this. the recepticle under the sink does.

422.34 Will allow some unit switches to serve as the disconnect. As long as there is a definite off position, and it disconnects the ungrounded conductor(s).

I read 422.34 and im having trouble understanding what the heck its saying.
if im reading it right i think its saying for single-family dwellings if you have a main breaker(why wouldnt you?) than a unit switch may be used.or is there something else here im missing?

I think you got it but the unit switch must disconnect all ungrounded conductors and be clearly marked.
Most units I see have a small LED light that stays on. This would mean you need a disco.
I am not sure why the article mentions the service disco as the other means of disconnecting. Baically I believe they want another way to disconnect the circuit. The circuit breaker would do that so unless the CB for the dishwasher is also the service disco I am not sure what the purpose of this is.
