Dishwashing
Doing Dishes, Washing Dishes
noun
You know the word 皿 (plate) and the word 洗う (to wash), right? You can probably guess dish washing is happening here, but this is a noun, so it's the idea of dishwashing, AKA doing dishes, or washing dishes.
The readings are the individual vocab words (you can tell because there's a bit of hiragana stuck on there). It's the reading for 皿 and 洗う combined.
