I found my PowerClean in 2014. My absolute pride and joy, and I wouldn't give it up or sell it for a thing. It was in pretty neglected shape at the time but for these machines it's really hard for someone to actually harm them, and I dismantled it piece by piece, down to the bolts, and reconditioned and cleaned every single part by hand, and a few parts, like the motor seal, I replaced new just because that's the kind of thing I don't take chances on. I also found a newer 2007 model, and parted it for the updated racks and the nicer light grey wash arm themes versus the old beige look. It's been going strong since then and has been my proudest restore work and the best investment of time I've ever done.
At the moment it's in storage awaiting when we move in March, but it's spent alot of time in our kitchen. I've done some sound insulating by adding felt padding to the inside panel which made a world of difference over the standard Quiet Partner/Quiet Pack, but I'm planning to get a box of Noico sound mastic and do the same to the PowerClean that I've done to my 520 model that is in the kitchen now and will stay with the house. It took a fairly mid-line machine with not much dampening and brought it down to the level of what my 920 model and KitchenAid were, around 46-48 dB, so I'm expecting it to make the PowerClean sound even more gorgeous.
I concur with everyone's advice: do NOT let that machine pass you by. Grab it, give it some TLC, and it'll last for years and will clean anything you throw in it, including a cake if you so desire. These were hands down the best designed dishwashers to ever grace the planet and still are holding strong even 15-20 years later and don't look terribly aged either. The one I have in black with the sleek control panel looks just as modern as the other appliances in my kitchen that are only 6 years old.
