There are products like this (Google for "UV sterilizer box"). Pretty sure they work fine. But they take a lot longer than wiping with soap and hot water or disinfectant. For dishwashers it's going to be difficult to make sure you expose every surface of every utensil, compared to filling the machine with hot air and steam. You'd need a much more space-hungry design than standard models.
