My guess is spacing issues in non-US homes. When I was growing up in the US, running the dishwasher meant wheeling it over to the kitchen sink, hooking it up to the hot water tap, and then running it. Friends had their dishwashers built-into the kitchen cabinetry and had a water line directly to it. I live outside of the US now in eastern europe, and for older apartments, dishwashers aren't really possible unless you do specific renovations to run piping for it. There either just isn't space or isn't piping (or both) to make it work. Newer apartments it's much more common, but the dishwashers are about half-the size of what I grew up with in the US.
