What does dishwasher mean?
A dishwasher is primarily an electrical kitchen appliance that cleans dishes, cutlery, and cookware by spraying them with hot water and detergent. Found in most modern households across the English-speaking world, it has become one of the standard fixtures of the domestic kitchen, alongside the refrigerator and the oven. The word also carries an older, secondary sense: a person who washes dishes by hand, particularly someone employed in a restaurant kitchen — a job often associated with entry-level work. Common verb pairings include loading, unloading, and running the dishwasher, while the derived adjective 'dishwasher-safe' signals that an item can withstand machine cleaning without damage. Etymologically, the word combines 'dish', which descends through Old English from Latin 'discus' and ultimately Greek 'diskos' (a round plate or quoit), with the agentive noun 'washer'. Its everyday familiarity makes it useful both literally and idiomatically, as in phrases describing domestic routines or humble first jobs.
A machine that automatically washes dishes, cutlery, and glassware.
"We bought a compact dishwasher for the small apartment."
This is by far the dominant modern sense.
A person who washes dishes, especially one employed in a restaurant kitchen.

Standard regular plural, used for both multiple appliances and multiple people washing dishes.

The word traces back through Old English 'disc' to Greek 'diskos' — meaning your dishwasher is etymologically related to a discus thrown at the ancient Olympics.

Etymology of dishwasher
The word 'dishwasher' is a straightforward English compound of 'dish' and 'washer', formed with the agentive suffix '-er'. 'Dish' derives from Old English 'disc', borrowed from Latin 'discus', itself taken from Greek 'diskos', meaning a flat round plate or a discus thrown in athletic contests. The compound arose in the nineteenth century as mechanical dish-cleaning devices were invented, with Josephine Cochrane's widely publicized machine of the 1880s helping popularize the concept. Cognates of the root include 'disc', 'dais', and 'desk'.
How dishwasher is actually used
In everyday speech, 'dishwasher' almost always refers to the appliance; the human sense is understood mainly from context, especially in discussions of restaurant work. The compound adjective 'dishwasher-safe' marks items that can withstand machine washing.
