A dishwasher is a household appliance designed to clean dishes, utensils, and cookware automatically. It uses water, detergent, and a combination of spray arms to remove food particles and stains. Dishwashers come in various sizes and styles, including built-in, portable, and countertop models. To operate a dishwasher, users load dirty dishes into racks, add detergent to a designated compartment, and select a wash cycle. The machine then fills with water, heats it, and sprays it onto the dishes. After the wash cycle, the dishwasher drains the dirty water and rinses the dishes before drying them, making cleanup easier and more efficient.
