Vinegar is also good for dissolving lime, which builds up in the washer when you have "hard" water and will make it stink - not a mold stink, though, more some kind of bacteria that loves to live in lime. In this case it has nothing to do with residual water. And vinegar is a pretty good cleaning agent all by itself.
