In Italian too “la lavatrice”. And the dishwasher too, “la lavastoviglie”. btw we have gender fluid nouns like “the table” = “il tavolo” / “la tavola” with slightly different usage patterns.

Italian and Spanish are easier than French because the final -o (masculine) or -a (feminine) usually give a hint, with a few expections you have to learn by heart (“la mano” meaning “the hand” in both languages for example)…
