Just a question out of pure curiosity.

New dishwasher installation, manual calls for a 20 amp breaker. No problem,
run 12Ga/2 (with ground ) Romex from breaker to J-Box, Run 12Ga/2 (with
ground ) BMX up to dishwasher. Open dishwasher electrical cover and it has
16Ga wire?????

So if code requires 12Ga for a 20 amp circuit how can the UL/CSA labeled
Kenmore dishwasher have 16GA wire for the final connection. Same thing with
the garbage disposal system.

Any thoughts on this one?

The breaker is there to protect the house-wiring (and the house) in
case of overload.
Not the appliance.
