Spraying water from the line all the time would be very wasteful.
Comment on With bathing, water recirculation is more easily accepted.

That doesn’t sound right, but I don’t know enough about dishwashers to dispute it.

It’s the case for all dishwashers I know about. It’s not that weird if you think about it. When people wash dishes by hand, they often wash a bunch of dishes in the same basin, with the water becoming increasingly dirty. Depending on how dirty and how much they care, they’ll change the water occasionally. Then they’ll give everything a rinse in clean water to get rid of soap. (obvs people do dishes on a variety of ways, but this is pretty common in western cultures.)
Dishwashers are the same, spray the same hot soapy water over the dishes for a while, until it’s dirty and most of the solids have been removed. Then drain and wash again with clean water. The soapy stage is about removing dirt, but the sanitising comes afterwards with the hot rinse and drying.
