Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Help Support :

Now, now, now... :-)

Some people enjoy these, and there are worse machines out there.  They're still assuredly worth posting. And remember, before the wash arms changed to stamped slots, they rocked the CR ratings for washing.  Not sure if this one is old enough to sport the goats-eye wash arms that cleaned up a storm, but it's still a handsome machine.  Plus it's not a wash tower...
 
I liked this design and if I bought it, I wouldn't worry about a daily driver. I was hoping to hear another view; glad you dropped by Nate. I haven't used these DW's, so maybe my impressions aren't based on useage, just design. Thanks again for another view.
 
What's that vertical metal thing I spy in the middle

The vertical feed tube to the upper wash arm.  I can barely see the upper wash arm in the picture under the top rack when I blow up the picture.  Back in 1968, this comparable model did have the pop up wash spritzer (I mean tower).  But by this time in their line, only the BOL had the pop up tower. 
 
Ah, a pop-up tower.  OK, now I get it. 

 

So even with just "Full Cycle" and "Rinse/Hold" options this wasn't their BOL model?

 

Phil, Waste Kings and Thermadors were the same machine.  For a while, anyway.
 
Wow, that's as bad as our super BOL portable '70 Wardgidaire top-loader with just a timer knob that popped out when it was done.

 

Still, I think even a BOL WK would seem luxurious in comparison.
 
They weren't that bad!

At the time they were being produced Waste King & Thermador machines were considered premium brands. Their two arm machines did an acceptable job of cleaning. I knew many people who had Waste King dishwashers of this design and they were very happy with them. They suffered from two problems: 1)Poor reliability of their pumps (a major component!), and 2)They were slow to update their machines for more intensive cleaning & loading flexibility (a major issue in later years). And the steam feature was an interesting, albeit flawed, feature (due to the weak nature of the steam, and the pause it placed in the non-steam cycles). It makes me wonder if their engineers were truly thinking about how to update the design to be more relevant to the changing needs of the home kitchen.

With plenty of hot water and phosphate detergents these non-steam machines cleaned well. And I've always loved their design. Just not very energy efficient.

Here are some pics of my WK SS911 portable.

The sequence was the same as normal (W,R,W,R,R,R,Dry), but the wash cycle was extended by about 12 minutes and the dry cycle was extended by 12 minutes. This was accomplished by a separate cycle extending timer. The idea was to provide longer washing to remove heavy soils. But here's where Waste King screwed up....the heating element is not on at any point in they cycle until dry! The wash water cools too much and the soil removal is not as thorough. The extra drying time was touted as being beneficial in areas of high humidity. The user guide mentions that the you can opt to use only one of the extra time periods (wash or dry) by pushing the Super Scrub button at the appropriate point.

Too bad they never quite developed an effecting water heating system. To get good results with these machines the water heater needs to be set at 150 degrees.
 
WK-TD Dishwashers

Thanks for all the great information Alan, you are truly one of the great DW minds.

 

Having worked on a few hundred WK-TD DWs they just never interested me to the point that I would ever install one in my home.

 

In addition to the problems that Alan listed we saw many problems with detergent dispensers [ they usually just let the detergent wash out ] even if they operated properly, broken door springs and worn out door hinges [ welded to the tank and not replaceable, oh well ] and Horrible pump and motor durability.

 

All that said the cleaning performance was never great, in fact IMEO NO DW ever gave great results that did not have a wash filter, this is why they needed THREE rinses and again no DW should ever need three rinses to get rid of the detergent laden wash water [ dishes are much easier to rinse than clothing].

 

Overall it is a real toss-up as to whether a D&M or a WK-TD is  worse  machine, in any event I am glad that we have excellent examples of both for the museum display.
