My dishwasher manual specifically tells me not to pre-rinse.

Commercial dishwashers sterilize dishes with high heat and steam. It's expected for dishes to be sprayed first by the person doing dishes with a high pressure hose to rid solid food before wash cycle.

Consumer dishwashers instead let enzymes do the work.

So, different applications.

Sure, but I was responding to the commenter saying you really should pre-wash at home too.
