Vintage Dishwashers, especially Potscrubber and KA
We have had several KA, both the real Hobart and the, well, Whirlpool version.
Our 15 (portable) does clean extraordinarily well and is all original. It, like all vintage KA dishwashers, demands considerable attention to detail in loading. I've figured out through the years how to load both racks such that everything comes out spotless - but I will not pretend for one second that it's fun or remotely like loading a RR Maytag or any Potscrubber or vintage Miele.
In the remotest.
As to the other KAs (the real ones, not the Whirlpools), yeah, well, OK, it's like this. Yes, they use very good components and great enamel. With the occasional exception of upside down dispensers (I'll never grasp that one if I live to be 400 years old) they were very well thought out.
But - they still required enormous effort to load right in order to get things clean. Yes, if you did it right, they worked perfectly. But, please, guys and gals - don't pretend you have the freedom in just throwing things into one such as a Twenty-Eight Hundred offers. Even Consumer Reports, who automatically crowned KA Queen of everything, admitted that. Through clinched teeth.
Nothing I've ever used matches an RR Maytag for flexibility, followed closely by a Potscrubber with multi-orbital arm (when a whirligig works, that, too).
OK, so the whole durability thing. Here's where we get into discussions. I think it's perfectly fair for me, a dude who replaces appliances used in (now) over 100 rentals regularly to compare and contrast. The BOL AMANA which Whirlpool has had on the market for some time now just plain hold up as well as do the extra specially expensive BOSCH and the TOL Whirlpool stuff. The mechanical Hotpoint/GEs last forever, but their cleaning performance was castrated by the decision to shrink the water level below their designed capabilities (which were not adjusted.) Throw an extra 2 liters of hot water into the wash cycle of a new Potscrubber (yes, I know they don't call them that anymore, but they are) at the beginning of the cycle and, wow! It'll clean enormously better.
I loved my Mieles in Germany. They were outstanding. I love my Potscrubbers here because of two reasons:
1) I refuse, absolutely refuse to prerinse or prescrub.
2) You can just throw stuff in and it comes out clean without spending half an hour checking the photos (yes, I did) you made up showing the 'keep-out' zones and placements you need to get equally clean dishes out of a real KA.
As to Whirlpool - there's no questions about it, their design really and truly has reached the point where they work and work well. I'll never be a fan of them, but a dishwasher which can stand up in a rental for five to seven years is a good machine.
