Commercial Style Dishwashers -- No Home Models?

Why is it that a commercial dishwasher can run a complete cycle in less than 10 minutes, yet a home machine takes hours? Does the commercial model not dry the dishes?

  1. Correct, commercial dishwashers don't automatically dry the dishes. The extremely hot water heats up everything so that it can dry with its own residual heat. By the time the dishes have cooled to the point you can touch them, they're usually either dry or just barely damp.

    1. Most commercial ware washers complete a cycle in 90-120 seconds. Booster heaters heat the final rinse water up to 180-190 degrees, so the dishes dry on their own really quickly but you usually have to manually dry the flatware to avoid spots. There are under counter models (in the $3500-$5500 range) that would look just fine in a home kitchen as long as you have a lot of stainless steel appliances. I did see a TV show once (Ultimate Kitchens?) where the homeowner had purchased a commercial ware washer that had been cosmetically made up to look just like a regular home dishwasher, but I can't remember the brand name.

        Hobart makes commercial undercounter models but as you said, they are expensive!

      2. A few notes about a commercial model.
        They are very noisy.
        You should rinse before you put dishes in, they are not usually great at removing dried foods.
        They also tend to use a lot of water.
