Wait, what...? You leave your refrigerator and dishwasher behind? :)
I guess it depends a lot on your location and custom. Also if the appliance is "built in" (like an oven) or free-standing.
I've personally never left a free-standing appliance behind, and you certainly aren't getting my industrial-quality, 25 year old, top-loading washing machine for free....
That said, these things are negotiated as part of the sale. Buyers are aware ahead of time what they are or are not getting, they don't show up at their newly purchased house and go inside to see what appliances they have vs have to buy.
I've literally never bought a refrigerator, dishwasher, washer, or dryer in my life, and never moved one between houses. Certainly I've run into one of these that had been left behind by a previous owner that was just so-so, but never bad enough that I could justify the expense of replacing it.
As an example, due to a design flaw, the built-in ice maker in my fridge doesn't go more than a week without getting clogged due to water flowing all over inside it and freezing. It's a bit annoying, to be sure, but it's a lot cheaper to just have a couple old-school ice cube trays in the freezer.

I think most people wouldn't look at it that way. You'd be leaving behind your washing machine, and the next owners would get it "for free", but you'd be getting a different washing machine in your new house that the previous owners left behind "for free". But sure, if I was really attached to a particular appliance, I would probably want to bring it with me when I moved. I've never cared that much, though, and don't expect I will in the future.
(Also, while top-loading washing machines tend to last longer without needing maintenance than side-loading, they use so much more water.)
