Power Clean Thermal Holds

[Chetlaham]

How long were the typical thermal holds on your Whirlpool/Kenmore power cleans filter module dishwashers? What was your incomign water temperature? How many degrees F per minute did the heater typically raise the water temperature? Exact numbers are alluding me and I never payed much attention to my Power Clean way back when.

I love Whirlpool power clean dishwashers. In my opinion, they had the most advanced technology. That may explain why they blew everybody else off the map in terms of cleaning.

 

[Chetlaham]

I'm still grieving them. 

It is a loss I will never come to terms with. Its so painful.

 

Power Cleans were perfected technology in every regard. So simple, yet so effective. They were also the most energy efficient pump mechanism ever created. On top of the best cleaning and best soil handling. Nothing comes close. I can understand why other technologies were discontinued despite all they had to offer, but everything else that followed the power clean was countless steps backward except for maybe noise but thats it.

They were also the most energy efficient pump mechanism ever

I find this hard to believe for numerous reasons... starting with the fact that they're no longer being manufactured because of efficiency?

 

[Chetlaham]

Modern tall tubs leave at least several cups of water in the sump and their pump bodies requiring more water to compensate.   

 

Power cleans left no carry over, where 4.8 gallons left loads totally spotless, with no filter to clean and absolutely zero water wasted pre-rinsing.  

 

No mechanism can handle the level of soil or do the amount of cleaning with only 2 water change outs and a purge.

Modern dishwashers with filters, etc.

Only leave about 1/2 cup of water in the sump about the same as a power clean dishwasher.

I love my power clean dishwashers. Everybody knows that and they do a great job but they do use a lot of water and a lot of electricity. Modern dishwasher use half as much water and electricity, it’s the one thing that I have to justify as two whether I should be using these dishwashers because of all the power they use we run one of them every day.

When they tried to reduce the energy consumption on the power, clean machines and came out with that very brief cycle with just two water changes and a purge they did not work worth a damn we had many customers complain that the dishes looked awful that cycle only worked if you completely rinsed everything off.

John, why don't you retire your power cleans for a modern Whirlpool tall tub? Surely the same identical results are worth all that water and energy saved.

 

[Chetlaham]

Is this your machine John?

It uses a lot of energy, it has a porcelain tub, heating element lacks a safety high limit, repair parts are mostly NLA. Why use such an obsolete energy hog?

Is the "Pots and Pans" cycle the only cycle the heater is triggered on or is it the only cycle the water temp is thermostatically reached?

Whirlpool!

All cycles will delay for thermal hold if you select Hi-Temp wash option. The main wash and final rinse will than heat up to 145 degrees!

My dishwasher has a thermal delay on all of the eight full cycles (not Rinse/hold).  It can be connected to a cold supply.  Normal heats to 140°F for the main wash, 150°F final rinse.  Heavy is 150°F wash, 163°F rinse.

 

[tomturbomatic]

I love the Heavy Wash cycle which I reduce to 4 water changes giving a 10 minute lower temp enzyme pre-wash and then an approximately 20 minute heated main wash for super clean dishes. I do not trust cycles with only a single after rinse. When Consumer Reports tested the first APEX dishwasher, they noted that washing performance improved when the timer was reset to give a second rinse and subsequent models had timers that gave two rinses. In the KitchenAid machines that went to a single after rinse, the vinyl racks did not hold up as well as in the older models that gave a minimum of two after rinses.

 

[Chetlaham]

I remember those single rinse Kitchen-Aids. The final rinse was really long on some models, IIRC over 20 minutes. I wonder if that had something to do with the racks giving out, or the presence of detergent residue. Or just cheapened design.

 

Personally I think 3 final rinses each at 2.2 gallons compliment the Whirlpool Power Clean the best.  

 

[combo52]

Power clean dishwashers three final rinses ????

How did we go from your statement Chet of how the power clean dishwasher with one wash one rinse was the best cleaning dishwasher ever to one that has three final rinses which Whirlpool never made.

Here’s a picture of the last whirlpool dishwasher that I ever saw that had three final rinses SAU 500, The later versions of this SAU 500 went to two rinses at the end because they realized it was a waste of water and it didn’t improve the performance at all. John

 

[Chetlaham]

One Wash One Purge One Rinse

The power clean filer module still cleaned way better with one rinse overall than most tall tubs that used the same amount of water or more.

 

 

Now, if you want the best spotless results on earth out of the most soiled dishes and cookware two prewashes, one main wash and 3 rinses are ideal with a Power Clean Filter Module.

 

 

Whirlpool may not have found it wasteful, rather the pressure to keep building machines that use less and less water.

Unless you’re doing actual soil and load testing, this is AAAALLLLL FICTION.
Are you telling me, you know far better than the GENIUSES at Whirlpool, that the cycle sequences for the Powerclean need reprogramming?

I also don’t see any consideration for enzyme detergents.

 

[Chetlaham]

Johnb300M- please re-read my post, in particular this part:

 

<blockquote>
"...rather the pressure to keep building machines that use less and less water."


 

</blockquote>
The difference between me and even the best the engineers at Whirlpool being are that I am not bound to energy regulations. If 9-13 gallons of water are needed to get dishes clean then consumer are entitled to a dishwashers that use 9-13 gallons of water.

 

The appliance industry is riddled with countless examples where engineers had to sacrifice performance for energy efficiency. Like relabeling the light wash cycle to normal.


 

Which takes me to your rebuttal which essentially disagrees with the statement John (combo 52) made in post #5:

 

<blockquote>
"When they tried to reduce the energy consumption on the power, clean machines and came out with that very brief cycle with just two water changes and a purge they did not work worth a damn we had many customers complain that the dishes looked awful that cycle only worked if you completely rinsed everything off."


 

 

</blockquote>
You're telling me unless actual soil and load testing is done in a laboratory environment all these customers are spouting fiction? Ok. That is all I need to know.

 

 

Regarding enzyme detergent that is why I prefer a long main wash (40 minutes) instead of a thermal hold, so time is met regardless of incoming water temperatures.  

 

 

Your post is more out of zeal to defend energy efficiency than actual performance. 

 

 

The power clean filter module is the best soil removing, soil processing and soil flush away mechanism ever created. If a bit more water is needed to let it do its job with heavily soiled dishware than I think that is more than fair.

 

 

13 gallons of water is peanuts compared to all the water wasted manually pre-washing, pre-rinsing, scrubbing and soaking as forced onto consumers by tall tub dishwashers and energy saving measures.
