I have a KichenAid by Hobart Model KDS-20 . When I bought my house 17 years ago, the lady said it did not work. I just took her word and never messed with it. I got married two years ago. The wife said it would make her life better if we had one that worked. A friend offered to give us one that worked they just didn't like the color. So as they were on there way over with the dish machine I was taking out the old one I had. Turns out there was nothing wrong with it other than the water was turned off. I turned the water on and it worked fine. I put the other one in because I thought it would be more efficient and maybe it would do a better job and parts are still available. The new one is not as quite as the old one. Also the old machine is very heavy, it's built like a tank and still looks brand new. The wife is happy with the plastic GE I installed. The KitchenAid is still sitting in the kitchen, she's not happy about that.
