When I was living alone I had something that was called "table dishwasher". It was a little thing with only one drawer and I filled it roughly every 1-2 days.

An average (read large) dishwasher consumes ~12l of water per cycle. That's equivalent to letting the tap run for ~30 seconds.

A good dishwasher uses ~0.6kwh/cycle. That's equivalent to ~10l of hot water. Again, ~30 seconds of tap water.

Tbh I don't think I run the faucet for 30 seconds to wash dishes for the day. It's basically just cutting board, knife, a plate, and a bottle. 10 seconds max

I'll remember that on the rare occasions I cook up food for lots of people, though. That's definitely more than 30 seconds!
