How to say "error" in Japanese

• エラーCommon
  noun, suru verb, intransitive verbCovers errors in the technical sense, especially computer or machine errors such as error messages and system failures. This is the default choice when the error is mechanical or digital rather than a human mistake.
  彼かれのエラーがなかったなら我々われわれは勝かてたのだが。↗

  If it had not been for his error, we would have won.
• 間違いまちがいJLPT N3approx.Common
  nounCovers mistakes and errors in the everyday sense: getting an answer wrong, dialing the wrong number, or making a wrong judgment. It emphasizes that something was done incorrectly.
  この本ほんは間違まちがいだらけだ。↗

  This book is full of mistakes.
• 非ひJLPT N1approx.Common
  nounGlossed as fault, error, and mistake, but as a standalone word it is mainly used for moral fault or wrongness rather than practical errors. It is seldom the word you want for an ordinary 'error'; think 'wrong' or 'fault' in an ethical sense.
  彼かれは自分じぶんの非ひを認みとめましたか。↗

  Did he admit that he was wrong?
• ミスJLPT N3approx.Common
  noun, suru verb, intransitive verb, transitive verbCovers mistakes and blunders, typically human errors made at work or in daily life, such as a careless slip in a task. Slightly lighter in feel than 間違い, with a nuance of an avoidable slip-up.
  印刷いんさつミスはすぐに指摘してきされなければならない。↗

  Mistakes in the printing should be pointed out at once.
• 誤りあやまりJLPT N3approx.Common
  nounCovers errors, mistakes, slips, and bugs, and leans toward formal or written contexts: errors in a text, in reasoning, or in data. A good choice when you want a slightly more serious or precise word than ミス.
  私の誤あやまりは彼かれの怒いかりを招まねいた。↗

  My mistake incurred his anger.

For technical or computer errors use 「エラー」 or 「誤り」; for everyday mistakes 「ミス」 or 「間違い」; 「誤り」 suits mistakes in writing or thought, while 非 is largely a literary word for moral fault.
