That should be obvious then that they are cleaned off, set in the dishwasher to dry until it is run to "sterilize" them.

In most of the professional kitchens I worked in, sanitizing was the only purpose for such a machine. Human dishwashers took care of the cleaning. The larger kitchens would often have a machine that was specifically designed just for sanitizing. They might have gotten hot enough to sterilize but I couldn't say for sure.
