You mean those things with a door on either size so the rack goes through from one side to the other? Those are high temperature sterilizers that take hand-washed dishes and blast them so you can put them on patrons' tables.

The guy at the end of the article clearly had one of those (it looks like he probably said this but the wsj reporter cherry picked the quote, as it quotes him saying he could only use it for glasses at parties, not for plates with food residue. Bet he didn't call it a dishwasher since he's a repair guy).
