OMG
David I am so with you on this.
With all due respect to KA, and they definitely still have mine, my Thermador THD 3600 absolutely kills as the thread's title states. However, there's never a free lunch and there are quirks deal with. There's still a tower to dodge but it's stationary and the rack design avoids it without compromising the loading plan. The mesh of the silverware baskets isn't fine enough, as is witnessed by scratches on the door where things poked through, and downward. The mechanical timer clicks and clunks its way through the cycles which is OK until it hits "Dry." The rinse/hold cycle is overkill.
But this thing can steam-clean! Of course I expect clean dishes from any machine I own, but the challenging things like casseroles etc are where the men and boys part ways. This machine is about as macho as you're going to find. But even better is the fact that I no longer need to have a towel handy when unloading the top rack. The Thermador dries better than any machine I've used in the past. There is NO water left in anything. The rack's design seems to facilitate slanted cups, mugs, etc more than other makes, which helps in this regard.
The WK/Thermadors of this vintage are true workhorses and you'll know they're running, but they aren't trying to hide the fact that the contents are being taken to task. The sound is of powerful jets of water, not clanking dishes, because the deluxe tines prevent that from happening. The days of these machines are numbered. Parts are next to impossible to find. I'm glad I'm able to enjoy mine for as long as it will serve me.
I still love KitchenAid. If the Thundering Thermador ever needs to be replaced, it'll be a 90's vintage KA to the rescue. KitchenAid is to dishwashers what Maytag is to clothes washers. This really hit home with me when I picked up the KD 12P for Nate recently. It has been washing dishes for 57 years, right up until a couple of days before I came for it. After a short vacation in my garage, it'll be back doing what it does best in Nate's kitchen. Apparently there's no end in sight for this little machine. I had a KDI 21 for 18 years and loved it. After a horrible relationship with the Motley Maytag (I don't care how well it cleaned, and it did clean well) I'm treating myself to a love affair with a rare and unusual machine for as long as it will have me.
Oh, and if anybody knows about where to find parts, please advise. I know ebay isn't going to rescue me every time.
