A dishwasher is a household appliance designed to clean dishes, utensils, and cookware automatically. It uses water, detergent, and heat to remove food particles and sanitize items. Dishwashers come in various sizes and styles, including built-in, portable, and countertop models, making them suitable for different kitchen layouts. The operation of a dishwasher typically involves loading dirty dishes into racks, adding detergent, and selecting a wash cycle. Once started, the machine sprays water onto the dishes, rinses them, and then dries them using heat or air. This appliance saves time and effort compared to washing dishes by hand, making it a popular choice in many homes.
