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

Built-In Grinder

The WP Dura Wash DWs have a very tough and sharp main wash impeller hat grinds food very well, Try reading the manual.

 

Self-Cleaning DW Filters, Agreed Louis nearly all better DWs today do a good job of keeping their filters clean if you use a proper combination of detergents for local water conditions etc.

 

Chester is talking about just having a screen in the bottom that catches nearly everything and has to be cleaned every load, Yuck.

Thomas,

I fail to see any resemblance between the much smaller dishwasher in the video and the Siemens you showed me. The one in the video is not only a glass one without a dispenser but layout, sizes etc. are all different too. I don't know where you got the idea that those are the same while they don't even look alike a tiny bit.

And then there is the fact that the recent designed Siemens and Bosch compact built-in dishwashers is much more recent than the much older dishwasher in the video.

Bosch and Siemens compact dishwashers are built in Zaragoza in Spain, not in South America.

Bosch doesn't even sell compact dishwashers nowadays in South America.

There is a Electrolux compact dishwasher that looks more like a Bosch than the one in the video, but that one too is not similar to Bosch and Siemens products. Different racks, dispensers and other innards.

BTW, we discussed Bosch compact dishwashers before, you were wrong about them back then too.

We had over the years four different variants of the GE PotScrubber. Though it had design flaws by todays standards with water usage. They were very good cleaning machines. Good enough, that the GSD 1200 was the top rated machine by Consumer Reports during the 80s.

We never pre washed, but did scrape, and it was rare, very rarely that we ever took a dirty dish out of the machine. It used good hot water, and with a good detergent had very satisfactory results.

The GEs were simple machines, as I mentioned in a previous post. Single motor one direction motor which ran continuously during the wash cycle and then basically two solenoids (fill valve, drain valve) and a heater. The ones we owned had mechanical timers and only repair was due to it eating a screw that fell of a pan lid and got stuck in the disposer. A soft food disposer that were actually two spinning blades where one pivoted at the center, processing near a screen.

What limited grinding the durawash impeller does by coincidence ends up redepositing all over the inside of the machine. The manual can say or claim anything, marketing hubris is one heck of a drug. 

 

I don't see a dura wash mechanism over the powerclean your Kitchen, both us know it leaves particles behind.

 

   

Self cleaning or not, a fine filter in BOL machines would have saved water and electricity. Don't like having to clean it? Buy a more expensive machine.  

 

 

 
 
GSD1200

These had a filter screen in the back that caught food particles. Absent on GSD500, 600, 640 and a few others.

 

The two wing macerator came latter, the originals were a single steal wire. 

 

If these machines used a separate drain motor water usage would have been cut by half and clean-ability going up. 
 
GE dishwashers that had an aux pump on the sump were able to go from 3 to two final rinses and reduce the number of prewashes for the same cycle.

 

Interestingly, when GE went from their plastisol to their permtuff models reducing the size of the sump (in comparison) they went from 3 final rinses at about 2.5 gallons per charge to two rinses at 1.8 gallons per charge. However, that did not prove to be enough as they went back to 3 rinses in the latter 80s- one 1.3 gallon and two 1.75 gallon charges.       

 

In the 90s they reduced the size of the sump boot and pump body again going to 3, 1.3 gallon final rinses.
 
They've all

done it. Cheaper, lighter, quieter, supposedly more efficient. Easy to change a failed drain pump, and if the wash motor/pump is a side mount or below tub mounting witha wide hose between, that too.
