Learn more about how a dishwasher works
A dishwasher is a device used to automatically wash dishes.
Unlike washing dishes by hand, which relies on physical labor to remove dirt, a dishwasher washes with hot water, typically between 45 and 75 °C (110 and 170 °F).

Working principle:
A mixture of water and dishwashing detergent is pumped into one or more rotating sprayers and the dishes are cleaned with the cleaning mixture. The mixture is recirculated to save water and energy. This is followed by a main wash with fresh water and detergent.
After the wash cycle is complete, the water is drained from the machine; more hot water is introduced into the tub via an electromechanical solenoid valve and the rinse cycle(s) begins. After the wash cycle is complete, the water is drained again and the dishes are dried using one of several drying methods.
In addition to domestic units, industrial dishwashers are available in commercial establishments such as hotels and restaurants where a large volume of dishes must be washed. Washing is carried out at temperatures of 65–71 °C (149–160 °F) and sanitization is achieved by using a booster that provides 82 °C (180 °F).

Size and capacity
Dishwashers that are built into standard kitchen cabinets have a standard width and depth of 60 cm. Portable dishwashers are available in 45 and 60 cm lengths or 18 and 24 inches wide, with drainboards and attached countertops. There are also dishwashers available in sizes according to the European Gastronorm standard.
Dishwashers can be standard or high-bay designs; standard bay dishwashers have a service plate under the door, allowing for easier maintenance and installation.
