It is a beautiful machine. You can add more insulation, especially on the back of the lower panel and kick plate like the newer KitchenAids have. It can easily take a 2 or 3 inch thick piece of fiberglass behind the kick plate and that much on the back of the lower panel; you had to push the lower panel into position to line up the screw holes when installing the machines when they were new. If noise is a problem through the walls and floor, I found some fantastic sound insulation when I was searching for something else on the Internet. If I bookmarked it and can find it, I will share it. Slabs of acoustical dampener are sold in auto supply stores. Removing the outer door panel and gluing some of that on the outside of the door makes a big difference. Often the undercounter opening will allow room for an additional insulation blanket over the tank. You can take unfaced fiberglass to the floor at the back of the dishwasher without interfering with the dry fan.
