Congratulations, Jeff!
I don't know why, but I've always found it charming the way the Prewash light goes out and then the Wash light comes on a half second later with the opening of the water valve. Sort of the one bit of evidence of the complex electromechanical controls underlying the simple pushbuttons and lights.
I'm pleased that so many people are finding and using these machines for daily use (so to speak). I think regular use keeps them young. And it's possible that a lot of them are still in use in their original installations and are just becoming available to collectors (like Jeff's was). I got my first dishwasher (a KDS-17A) in 1998 and hoped it would get me through 2 years. Now 8 years later I'm still using it--it's been in 4 different apartments now! (Of course, 8 years ago I never dreamed that it would be the first of a fleet of dishwashers!)
Good times
T.
PS Jeff, I love the old flooring visible under your DW!
