I have a 1969 KitchenAid KDS-16 Superba dishwasher that I am finally willing to sell. It was in our historic, 1920 home that we purchased 30 years ago and I have maintained it all these years (with vintage parts found mostly on this web site). It has been a great dish washer and served our family very well! The interior and exterior are in very good condition. But it is now making a loud, high-pitch sound. I replaced the pump seal, drain valve, and impeller, but it still makes the noise. So, I have decided to finally replace it, though I know I will be disappointed with a modern unit. I also have the original Installation Instructions.
