So I sell appliances at Lowe’s and I have also worked in a professional kitchen. Here is the difference commercial dishwashers are akin to a sanitizer than an actual dishwashing machine these machines use a combination or chemicals as well hot water their cycles generally run for 3-5 minutes.
Your residential dishwasher works in a much different way, these machines use use a set amount of water along with a heating device to keep the water hot. Some machines have a sensor function as well that sense the parts per million to know if it is done or if it should keep going. Other dishwashers include a garbage disposal in the unit as well.
