Washer and disposal hook up

If the dishwasher doesn't come with a factory installed cord, I install a appliance cord and put it into a GFI outlet under sink base.

Is there anything saying you can't?

I wonder whether the instructions address converting them to hard-wired as an option.

A Bosch 500 I recently put in had a cord from the factory, but there was an optional hardwire kit you could buy.

The hardwired option still has a cord but instead of it terminating into a 5-15 plug it has a non metallic J-box on the end of the cord.

Inspectors around here dont always trust us to size the cord. They sometimes ask to see the installation instructions, as 422 .16(B)(2) says the cord you use has to be 'suitable for the purpose in the installation instructions'. Which is silly. You should just be able to size the cord based on the namplate.
 
So far after 40 years in the trade I have never hardwired or seen a hardwired residential dishwasher or disposal.

In the Bay area prior to the mid/late 70's the standard was dedicated 20 amp circuit for both appliances. Then eventually most jurisdictions required individual circuits for each appliance. 14/3 HR to duplex receptacle with 2P 15 or 2 15's with handle ties. When AFCI/GFCI requirements became a thing we changed to 14/2/2 HR with 2 15 amp DF breakers handle tied.
 
I failed to mention, none of the disposals I've installed had cords either. I buy an appliance cord and put on them. Guess it depends on where the disposal is bought. All the ones "Big Blue" sells (that I've seen) don't come with cords. I have put air switches on a few.

I have always had to install an appliance cord on every disposal I've installed. If I had to guess, I'd bet the majority of the disposals were already installed and I had to crawl inside the cabinet to wire the cord.
Painful!

Same here I think its under 430.53 that the motor has to be 6 amps or less. 10A or less for the dishwasher per 210.whatever.

So, on the topic of supplying a dishwasher and a garbage disposal from a single 20A 120V branch circuit:

I would think both appliances are considered fastened in place, so 210.23(A)(2) does not limit the dishwasher to 10A.

As to Article 430, is the dishwasher considered a motor load? If we are to treat it as such, wouldn't the nameplate need to specify the motor FLC and the other loads separately, so we could apply the various article 430 requirements appropriately?.

Anyway, as to the 6A limit in 430.53(A), that exists because normally with a <= 6A FLC, the maximum SCGF OCPD would be <= 250% * 6A = 15A, so it couldn't be on a 20A circuit. 430.53(A) give you permission to put multiple <= 6A FLC motors on a 20A circuit. If the motor FLC is bigger than 6A, then the maximum size SCGF OCPD is already 20A, and likely 430.53(B) would allow the install.

Yep!
Sometimes, if I have the key/wrench, I will take the disposal off and wire it. That's if the plumbing is either not done yet or not complicated.
