DISHWASHER

Dishwashers are appliances designed to clean dishes, cutlery, and cookware efficiently, saving both time and water compared to manual washing. Widely used in homes and commercial settings, they automate the washing process with cycles of spraying heated water and detergent, followed by rinsing and drying.

Modern dishwashers come in various types, such as built-in and portable models, and feature components like pumps, spray arms, and control panels. With advancements like energy-efficient modes and smart connectivity, dishwashers have become essential in contemporary kitchens for their convenience and resource-saving benefits.
