A dishwasher is a machine that uses extremely hot water and specialised detergent to clean dishes, glassware, cutlery and other kitchen items automatically. There are consumer and commercial machines which serve the same purpose, but with differences in capacity and temperature.

The earliest version of a mechanical dishwasher was patented in the United States in 1850. The inventor, by Joel Houghton, referred to the device as a machine for cleaning crockery or other types of table furniture. This device included a cylinder with a rack to hold the items being washed. A hand crank made the rack move while water splashed onto the items as they rotated in the machine.

The next iteration was introduced in 1886 by Josephine Cochrane (a wealthy socialite) and George Butters (a mechanic). The rack and water jet system they devised was also hand powered, and it was displayed to the public at the 1893 Chicago World’s Fair. The invention from Garis-Cochran Company (later to become part of KitchenAid) garnered much attention - particularly from commercial users - and it was awarded the highest prize at the fair for "best mechanical construction, durability and adaptation to its line of work".
