How to say "dishwasher" in Japanese

• 皿洗い機さらあらいき
  nounThe machine that washes dishes, literally 'dish-washing machine'. Straightforward and easy to parse, and a reasonable word for the appliance in everyday conversation, though 食器洗い機 is the more usual name.
• 食洗機しょくせんき
  nounAn abbreviation of 食器洗い機 naming the same appliance. Compact and common in advertising, product listings and casual writing, but it is a short form, so it can look informal in careful prose.
• 食器洗い機しょっきあらいき
  nounThe standard everyday word for a household dishwasher as an appliance. This is the machine, not a person washing dishes, and it is the safest choice in most spoken and written contexts.
• 食器洗浄機しょっきせんじょうき
  nounA more formal, technical name for the dishwashing machine, using the Sino-Japanese term for washing. Typical of manufacturer specifications, manuals and commercial equipment descriptions rather than casual talk.
• ディッシュウォッシャー
  nounA katakana loanword covering the same appliance. Understandable but marginal; it is seldom the word you want, since native terms like 食器洗い機 are far more natural for the machine.

All five words name the dishwashing machine, not the person; 「食器洗い機」 is the everyday choice, 食器洗浄機 is technical, and the others are variants or marginal, so pick by setting rather than sense.
