I think if a disconnecting means is required then it should be a disconnect. Most add on breaker locks that are installed fall off the first time the cover is removed. If the disconnect is so important then a disconnect it shall be. I do know the code allows a breaker lock to be used and have used many.

Yep a DW is motor driven so I agree with the Inspector. 422.32

My dishwasher has an off switch. Wouldn't that fall under 422.32 Exception? Is the dishwasher cord and plug connected? If so you don't need to add another disconnecting means if it's accessible. 422.33 (A).

Is there a def. of what makes an appliance "motor driven"? I can understand a garbage disposal or a fan unit being considered "motor driven". On the other hand I had thought the main use of electrical power in a dishwasher was to heat the water and a small motor pumped the hot water through the spray arm. Is that motor significant enough to make the dishwasher "motor driven"?
OR
Is it just that "motor driven" is intended to convey that the appliance has a motor? Of any size?

One explaination I got from our State of Wisconsin Electrical inspector was that the controller for the dishwasher was inside the appliance and that led the appliance to be considered motor driven.

Any thoughts?
