A dishwasher cleans the equipment, plates and silverware used in a restaurant business. After guests finish with their meals, a bus boy brings the dishes and silverware to the kitchen area where they are cleaned. The dishwasher dumps garbage, wipes and sprays dishes and then places them in a dishwasher.
Dishwashers also typically help clean the kitchen area. This role may involve sweeping the floor and wiping down the counters in the work area. The dishwasher also wipes down cooking equipment used by chefs for food preparation. After the dishes are clean, the dishwasher returns each item to its appropriate storage area.
