Washing dishes at a professional level is different than in your own kitchen. Many restaurants and facilities have large, commercial quality washers able to wash several trays of dishes quickly. Dishwashers unload the cutlery and dishes brought to the kitchen by Bussers while loading and organizing them into trays for the washer. Commercial dishwashers are not always able to accommodate larger pans and pots so they may occasionally need to be washed by hand.
