The dishwasher installation instructions should give you the electrical requirements. Other than portables, I've never seen a dishwasher that plugs in - the instructions for the LG unit I just put in didn't even mention that. If it did, I wouldn't do it anyway - hardwiring would be cheaper.

I've never lived where a visible disconnect switch was required, but I had to put a locking device on the breaker in the panel. Kind've silly really, since no other breaker requires one. But at least it was inexpensive.

The Little box on the Dishwasher says this

-Connect to a separate circuit with a fuse or circuit breaker Rated for 15 amp min or 20 amp max 120v ac 60hz only

-Do not use an extension cord

-permanently ground the dishawsher in accordance with the national electrical code and local codes or ordinances
We called an electrician last week

Wants $165

$55 an hour+$25 for materials

Would be using 14/2 wire

Everyone keeps saying a 20 amp fuse with 12/2 wire,so I don't know

My plan is,Run the wire though the joist's and have him hook the dishwasher up and at the panel.

$55 is fine not $165

Should I buy a Roll of 12/2 or 14/2

I don't want to do all this work and the breaker keeps popping if I choose 14/2 even though the electrician says that's what I need.

Either size wire is fine for that DW. The #14 will cover the 15 minimum circuit size and the #12 would cover the maximum circuit size required.
Answers based on the National Electrical Code. Local amendments may apply. Check with your local building officials.

DW & disposal are allowed on the same circuit
So I would run 12-2 & install a 20a breaker just in case

Run 12/2 if it would help you sleep at night.

The instructions cleary state that you can run it off a 15A circuit so thats what I would do and still sleep good at night.

12/2 is barely more money than 14/2. Just go with that. You can still use a 15A breaker if you want with 12/2, but I'd just go 20A.

If you plan to hire an electrician, and he won't use 12/2 like you want, get another one. He is working for you, remember?
