Single Rinses on Dishwashers

[washer111]

Lately, I've been browsing the Searchalator for odds and ends of information regarding older KA dishwashers (23 series and lower). It seems these machine often ran only single rinses proceeding after Wash phases (Or, not at all). It also seems that many newer machines are only doing single rinses and/or combined with a "Purge Rinses." 

I've put up with a newer machine that did this, and wasn't particularly impressed (Granted, it was only the Quick-30 cycle). Etching, Wet dishes and plenty of chemicals for all...

 

So are we likely to see this trend continue with stricter EnergyStar guidelines (and JetDry being phased out?), is this seriously harmful to the health of you, your family and your dishwasher or is it perfectly acceptable with modern "All-in-One" style detergents? (Including powders, with some even including Rinse-Aid and "Salt" functions now).

This is why I pray that my appliances outlive me. I had experience with single rinse KAs with electronic controls so it was not possible to reset the timer for an additional rinse. I did not find it satisfactory. It is sad to see our once great appliance heritage hobbled by these stupid restrictions. There used to be jokes about librarians wanting every book to be in its place on the shelf with no readers to disturb the order. I am beginning to think that people in charge of our water use have the same idea about it being better for every drop of water to be safe in the reservoirs instead of going through the system and being used. I can't figure out what is so bad about sending a few extra quarts of clear hot water into the drain lines. It's not like it was contaminated with horrible things like motor oil or copper sulphate. It just shows the insanity of people being put in charge of things about which they know little but have to come up with draconian measures to show that they are working hard and deserve a promotion or more funding for their agency.

Quick-30 cycle

I'm guessing that you're referring to the fastest cycle on a Dishlex there. You'd know that this is only intended as a very light wash cycle to start with and should be used with a reduced detergent load.

As for wet dishes coming out, well I used it at Christmas when we had 27 people for a 12 course dinner - it worked a treat. The wash is a proper 65c and the rinse is either that or 70c. If you open the door as soon as it beeps, the dishes are dry in under 3 minutes just from evaporation.

No, as for jet dry, since when has that product been available on the market here or for that matter, since when has Australia used the US 'energy star' rating or guide?

Of course I realise that... Though some would not be moved regarding it. I know the main wash was 65, which was pretty good for a short cycle, but I'm sure the rinse was cold... It's been 4 years though, so it's hard to say. I know the results elsewhere on that thing weren't great either (for us). I'm surprised that Disex didn't just run two super short rinses, even at low temps. The Delicates cycle on our DD gives three rinses and a good, warm wash and hot final rinse in 50 minutes (timed today). Great results. Time excludes 30 minute fan dry and 10 minutes were shaved from quick hearing, even with a cold connection. Or, Fast Eco gives a warmish wash and two equivalent rinses in 33 minutes. Great for computer keyboards!!!
Jet-Dry is actually a Finish product! I use its name since that's what many call the rinse aid these days...

Both Kenmore UltraWash machines that I have owned only used a purge followed by a single rinse unless you used the Pots and Pans Cycle which then used 2 rinses and then no purge. I have always been happy with the results. To be honest, I think many older machines did multiple rinses partly to purge the water lines and raise the temperature inside the machine so that the final rinse was hot enough help cut down on spotting.

I took a quick look through my KA literature stash and at least from the KD-10 through the KD-20 there were ALWAYS at least 2 rinses after the wash phase. I can say for certain that my KD-12 (1958) does 2 rinses and also that my KDS-16 (1969, non-soak model) does 2 rinses on the Normal and Light cycles and 3 rinses on Heavy and Sani.

My 2000 GE does only one rinse after the main wash on every cycle and its performance is more than satisfactory.

Our Older Kenmore 18" DW Only Does One Rinse

As well, but happily it has a mechanical timer so one can (and often does) reset for a second rinse.

Dishwasher is at least from the 1990's so single rinses cannot be that new of an invention.

As far as I am aware, it is only called that in the America's.....

Been there, done that - never again!

The kitchen our landlord installed came with one of these "special offer" dishwashers: it was loud (55dB), guzzled lots of water and didn't clean all too well. The worst thing was that every single cycle only had one rinse. Eventually, I just ran the 90(!) min. Quick cycle (wash-rinse-dry) to get a prewash and a wash, then stop it before it went into the drying cycle and started the cycle over to get a two rinses. Talk about Automatic Dishwasher. I put up with this sh!t for one year and replaced it with a Bosch: much quieter, better cleaning, more efficient and twice as fast. Oh, and fully automatic!

Here's what the final rinse looked like (without interfering) in the old dishwasher. This is even without rinse aid, which tends to make the water a little cloudy.

That rinse water does look rather cloudy. Would the glasses come out cloudy as well?

 

[jerrod6]

With today's detergents containing enzymes, chelators, and whatever else, AND the fact that single dose tablets and pacs are being used so you can't control how much detergent is dispensed, I don't think I could ever take just one rinse.

So I wash a lightly soiled load with one pac, then here comes one rinse. You think the excess detergent is really going to be flushed away with this?

How about a heavy soiled load with lots of soil, so this soil is sitting in the water in the sump at the end of the wash pump out. Next comes one rinse to spray the remaining stuff around, and what doesn't get pumped out in this one rinse...well ...sits in the remaining water in the sump or in the interior pipes of the DW until the next run. I would be very uncomfortable drinking water out of a glass that went through this.

Everything came out with spots or a film...

 

[washer111]

Well...

Now I know why we got such crappy results from our Dishlex's Quick30 cycle. See above! 

 

Even for us, the 2nd rinse before the JetDry dispenses is still a bit bubbly/detergenty from the wash. I suspect running the Delicate or Heavy cycles is the reason why everything looks so much better with that 3rd rinse. 

 

[aegokocarat]

My slimline hoover does only 1 rinse, but it has a compartment for all in one tablets which can be used as a prewash dispenser. Its pretty good imo, not had any issues with it not cleaning properly, but I always use programme 1 (intensive 70*c) programme 3 (eco 50*c) or programme 5 (daily 60' 70*c)

[pierreandreply4]

its seems my kenmore elite 2005 dishwasher do a 1 rinse as well since i use the smart wash cycle the only time it would do the prewash is if i bought power or liquid dishwasher detergent other wise it go like this on my dishwasher

smart wash cycle with tabs

its start with a rinse then purge fill mainwash ect but i have to rely on the turbo zone system and hightemp wash option and on rare ocassion the steam sanitize rinse if things keeps up i have a feeling that there will be a very high demand for vintage refurbish older dishwasher models like tru kitchen aid ect of 1990 and earlier for good cleaning performance

 

[dj-gabriele]

I honestly don't think that a single rinse is harmful to our health but sure results might suffer a little!

Lucky my dishwasher does two rinses even on quick and ECO cycles and 3 on pots and pans and intensive so results are always impressive!

Anyway I should add that most of the machines currently on market have a single rinse after both quick and more often ECO cycles to save part of the second heating and economize on water for the energy testing.
A few brands got a different strategy of keeping two rinses even on the ECO cycle for hygiene purposes, counter-trend to most of the market, like SMEG but lowered wash and rinse temperature and added the aid of condensation ducts and fans instead of natural drying which most competitors use.

Had 3 GEs since 1990 and all had 2 rinses. The newest one was 2000 and all were mid-line with potscrub (thermostat wash) and normal buttons.

I consider 2 rinses just barely adequate and often spun the dial (yes dial, no electronic nonsense for me) for an extra final rinse.

Like Tom, given the state of the industry today I would NOT want to be in the market for replacement appliances. All my life up to lately, one had to go out of one's way to buy junk white goods. Now, cynically, that's all there is.
