 I have two Kitchenaid Superba dishwashers both are in mint shape.I have finally got my place almost done after a having to rip out everything that was in there.I got a 1984 Kitchenaid Superba that is in wonderful shape was used about twice a year and I scored that time-capsule Kds-20 Superba two weeks ago that was tesetd and thats it still has the stickers inside the dishwasher . I have never used any Kitchenaid other than the Kds-21 or newer so I was wondering which cleans better?The one thing I don't care for on the Kds-21 is they had that killer disposer in it but nothing can really get to it.The pumps are very different in them does one have more power?I am not talking about motor wise because they have the same motor in them but the older one seems alot simpler than the 21.I was just wondering what would yall do if you was me? | ||

Which KA DW is Better
The 20 has a better cycle design [ two final rinses ] the 21 has a much more robust and durable pump design, and the winner is a porclean tub [ 1984-1990 ] Whirlpool Power Clean Dishwasher, if you are really looking for the best cleaning most durable and easy to service and repair DW ever made, you wont find a better design than a WP PC DW.
I was talking to an engineer at SQ the other week and suggested that they need to start building DWs, I suggested they buy the PC pump design from WP and build a rugged SS tub DW to put it in, unfortunately he did not seem too interested in building DWs but I do appreciate that they are concentrating on laundry products, look what happened to Maytag when they started branching out. | ||

 Well, since we're talking about machines in your possession and a Whirlpool PC isn't among them, let's rule out that whole scenario right now.
I'd go with the 20 for its double rinsing and 100% Hobartness. I don't think decibel levels are that much different between the 20 and the 21, but you do get the added snapping sound on the 20. Neither are "whisper quiet" nor do they scrub quietly or anything else. It's just part of owning a KA, and there are machines of the same vintage from other makers that make a lot more noise.
If you're wanting the machine to blend into a more modern kitchen and if the 21 is a Monterey, that panel wins out.

I really lucked out on these dishwashers they are in perfect shape.That goes double for the KDS-20 which was tested for one cycle before they ripped it out with the matching trash compactor in there guest house. You are right when it comes to Whirlpool power-clean that is one of my favorites,but I have always loved the style of the Kitchenaid. Does the Kds-20 heat the water to 150F or a 140F when it first starts?I know that from what I have read the Kds-21 heats to 140F at least that's what I gathered from the papers I have read.There are some other things that I have read in the Kds-20 papers is certain cycles it says fill with 7 quarts and then I see it says 9 quarts on other cycles. The Kds-21 also talks about its motor being reversible but the Kds-20 does not say anything about reversing at all. Everybody in here loves the older ones it seems... I guess I will try them out and see which cleans better I also have that new Smeg dishwasher which is a fantastic cleaning energy saving dishwasher..The only dishwasher that can clean tall narrow glasses totally..
What is the added Snapping sound ????? Also what is Monterey mean ?? | ||

The snapping sound and the motor reversing go hand in hand... sort of.
The 20's motor runs one way only, so to drain the dishwasher, a solenoid valve snaps open and sends the water out the drain pipe. The 21 motor is reversible. It runs one way to pump water through the wash arms, and then stops and reverses to pump water out the drain. So there is no need for a drain valve solenoid to direct the water to the drain, thus no snapping sound. | ||
