Whirlpool Corp. "Clean Water Wash" system

[johnb300m]

For giggles, I was reading the patent for Whirlpool's Clean Water Wash system.
There's a lot of science in this system. It's a fascinating read if you're patient enough to make it through the gobs of patent legaleze.

I'll look through this this holiday weekend.   Hopefully I'll learn more ho0w my dishwasher works.

Thanks for sharing. I've had a KitchenAid with this system for almost a year now. It's fantastic.

We run a load once or twice a day, no rinsing, with Cascade Platinum. Once a month, I put a Cascade cleaner pac on the hottest, longest cycle. No complaints.

I'm surprised KA doesn't make a bigger deal about this system.

I assume that is the system my dishwasher has too. It is a Kenmore Elite TOL one from 2014. The spray arm on bottom for a KA fits it.

The Kenmore elite I have with this filter system was brought out under the Kenmore Elite brand August 2015, it's one of 3 models in the line that use this.  This filter system is why I would only settle for the KA equivalent or Kenmore elite.

I was very hesitant to get a dishwasher that had a filter but I'm really surprised that since November there has been nothing to clean out of it. However at least once a week or so I run Sani Rinse so maybe that does help to clean things out

You know what's funny?
As a nerdy little kid, I used to draw all sorts of machines and cars and houses.
And when I was on a brief dishwasher kick....I actually drew a pump system with a "spinning" filter to keep soil off of it.
I must've been 8 or 10.
And lo and behold, the idea lives. These years later

John B,

good for you! Once I made a filter for my 3 ft. backyard pool with spare washer parts my dad had in the garage.
They already were around, but the pool didn't come with one.
I mounted a motor to two scrap 2x4 pieces and joined the shaft to a whirlpool pump shaft. I removed the belt pulley, and used shaft clamps on the motor, and pump shafts with an extension shaft piece. I cut it off of an old seized up motor.
I used suds drain hoses and an old shop vac with a paper filter cartridge. I clamped the vac hoses to the washer hoses.

I wonder when/if Whirlpool will implement this design on their own machines, because it would only make sense. At the same time, I would be a bit miffed since I only just got my 920, but I wouldn't feel bad because of how beautifully it works. I've yet to need to scrub or clean the filter at all. On many "manual" filter machines, there's at least a layer of scum that develops around the top portion of the filter, but not here.

Now, this Smeg we have in our apartment in Brisbane at the moment...completely different story. I'm almost to the point already of just washing everything by hand. There is no degree of "self cleaning" to this machine at all. Blegh.

With the evolution

of laundry products and white goods in general to date, I expect Whirlpool and others to follow the global design concepts of Asia, and Europe.
Peg a SMEG for example. Smaller capacity, less energy consumption, cheaper quality.
Get any simpler or lighter and we're back to hand wash boards in the sink.
It wasn't my idea to populate earth to 8 billion.
If the population keeps growing, the global planners will have to house people in apartment blocks of 600 square feet each. The only room for cooking, storing food, and laundry equipment will be small appliances. Sound familiar as in China?
The USA still has plenty of vacant land, but there is the economic aspects. Unless people want to farm for themselves, jobs will be scarce enough in urban centers, and even more so in the heartland.
Climatic events can also impact arming like we had in the 1930's in the Dust Bowl of the great plains.
Grapes of Wrath. Pick our poisons carefully. There are safe as well as poison berries. I'm very glad I did not grow up or now live in a commie block.

Yes Laundress,

filter and retain until pump out, or partial drain (purge) and fill with more fresh water.
Although Kitchen Aid dishwasher also have turbidity sensors, so as well as they do filter, they still purge.
