There's no question that the KDS-20's are very handsome machines. Yours turned out beautifully. I love seeing the Hobart logo on the ID labels. It says in no uncertain terms, "THIS is a dishwasher!"
How significant is the noise reduction with the more generous insulation compared to the old machine?
I noticed that your fine particle strainer is metal. The one on my KDS-20 is black plastic. I would guess that indicates my machine is a later production series 20. I tried find a home for it, but now that I've got the ISE Classic Supreme to prepare for installation, I will take any interchangeable parts off of the KDS-20 if they're in better shape.
Your parents must be thrilled to have the identical replacement in perfect running order. Nice job!
