Can one of the (two or more) required 20A circuits for kitchen receptacles also serve a Dishwasher? (California Code)
No way.
You need at least two kitchen countertop receptacle circuits.  Those circuits can have nothing on them except:

Receptacles in kitchen working areas
Other general-use receptacles in the kitchen, dining area, and pantry.
A wall clock.
A gas oven/range with small needs for controls and oven light.

A dishwasher is definitely not on that list.
