Dishwashers are a type of household appliance that are designed to clean dishes, utensils, and other kitchen items. They work by using a combination of water and detergent to scrub away dirt and grime, and then rinse the items with clean water. Most models are designed to fit under a kitchen counter, and can be loaded with dishes by opening a door on the front of the machine. Once loaded, the dishwasher will typically run a cycle that lasts between 30 minutes and 3 hours, depending on the settings you choose. Modern dishwashers are typically energy-efficient and water-saving, making them a convenient and eco-friendly option for busy households.
