Installing a dish washer with a approved cord, putting the GFCI receptacle in the space adjacent to the dish washer I assume this would be under the sink? Drilling a hole through the cabinet? Does it need a separate hole or can the water supply hose,drain hose,and power cord go into same hole?

In regards to the GFCI under the sink what wiring method is allowed if its not attached to the back wall. NM,MC?
 
Same hole. No need to Swiss cheese the cabinet. You need to determine if it's subject to physical damage, if not then NM cable is OK if exposed.

I have never seen an under-sink cabinet that wasn't filled with all sorts of junk: trash cans, plungers, bottles of cleaning fluids, dish racks, spare parts, etc. I really can't imagine a scenario where an under-sink cabinet would not subject NM wire to the potential for physical damage. Am I missing something?
 
Recent cycles have art422 extend the length of S cord w/male cord cap usage to address mototorized disconnection >110.25< ,which would apply to any motorized kithen appliance (as well as ranges w/out bottom drawers). Trash compactors, garbage disposall, even larger range hoods all qualify.

Romex gets yanked on, drug through holes, stepped on, fastened in place with hammered in metal staples, and all sorts of other physical trauma when it's installed and survives just fine. Do you think a few boxes, bottles, and knick knacks going in and out of a cabinet is equal to or worse than all that?

The difference being that the installation is a one-time event. And hopefully the installer does the job properly and also inspects the wire for damage during the installation. But stuff being banged around in a cabinet by inattentive residents over the course of, say, 20+ years...? It doesn't really take that much to damage wire insulation.

If I were surface-mounting a box in a cabinet for a dishwasher or garbage disposer, I would bring the NM in through the back of the box. But I would still prefer a recessed box.
