洗碗机是清洗食具的机器，用以节省人力。

首个机器洗碗专利在1850年出现，由Joel Houghton拥有，他发明的是手动洗碗机。

蒸汽船发明人John Fitch的孙女Josephine Cochrane可算是现代洗碗机之母。她在1893年世界博览会展出她的发明。当时的洗碗机仍是手动的。1920年代有水喉的洗碗机出现。1929年德国的米勒公司制造出了欧洲第一台电动家用洗碗机。1954年美国GE公司生产了第一台电动台式洗碗机，不仅性能有所提高，而整机体积外形也有所改善比较融入家庭而不是钢铁外形。bunun Türkçe olması lazım

A dishwasher is a mechanical device for cleaning dishes and eating-utensils. Dishwashers can be found in restaurants and private homes. Unlike manual dishwashing, which relies largely on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot water, typically between 55 and 75 °C (130 and 170 °F), at the dishes, with lower temperatures used for delicate items. A mix of water and detergent is circulated by a pump. Water is pumped to one or more rotating spray arms, which blast the dishes with the cleaning mixture. Once the wash is finished, the water is drained, more hot water is pumped in and a rinse cycle begins. After the rinse cycle finishes and the water is drained, the dishes are dried using one of several drying methods (e.g. a heating element at the bottom of the tub, fans, Zeolites based drying, etc.). Typically a rinse aid is used to eliminate water spots for streak-free dishes and glassware.
