I, too have one of those quiet and efficient dishwashers. It's 60 years old and it's still around. The make is David P and it's a human model!
I hear ya David, I have one only it is a Laura S make, human model and a few years older than yours... works well still!! (just a little slow sometimes getting started)

kokopup- Did you tell her that a new one would do the same thing if she put sudsy soap in it too so there was no use in getting a new one?

Now and then we get a new deckhand on the boat that will do that and he'll spend the night cleaning up the mess it makes...
