What? No more warm water?

[henene4]

...

I dunno, but I never prerinse and almost all DW over here are cold hookup.

Sure, we could run much higher wattage heating elements.

But most run around 1800W top.
You could probably still run 1100-1200W depending on design.
That is a difference but given the difference between washer and dishwasher, cold water hookup for DWs in the US aren't that incredibly improbable to pull off with barely any difference in performance - given they were designed and more so programmed that way.

Actually, for many US DW, pre rinsing by hand seems even less useful.

Sure I would recommend scraping most stuff off.

But from what I understand, many DW run prerinses depending on incoming water temp.
So if it is low, it would just add another short prerinse.
And for that matter depending on the timing water temp might be down significantly again once the main wash happens.

I think with DW the debate is much more differentiated compared to "wash your week long damp stored towels in cold".

why not a hot rinse?

a hot rinse would cause horrible creasing. Like ironing your clothes into the position they are in the spinning drum.

<blockquote>Next thing they will be encouraging you to hook your DW up to the cold water line instead!</blockquote> Dishwashers with assured onboard water heating can run on a cold connection but that's an entirely different thing than directly washing in cold water.

warm rinse

One of the few things I miss about my Duet. Towels always seemed fluffier. Might just be placebo effect. Not sure.

Avoid click-bait

If you actually read the article, you see P&G isn’t suggesting you stop washing in warm or hot. They are merely trying to increase the number of cold washes.

At our house, we wash colors in Cool (vs Tap Cold), sheets and whites on Extra Hot or Hot, and towels Warm... sometimes Hot. Given the large volume of colors in this house, we are close, but not quite to their goal of 3 out of 4 washes in Cool.

Everyone's situation is unique, which is surely why P&G made a point of saying they aren’t trying to preach to people. Lighten up, have some fun, avoid the click bait. (...and still, I agree that too many people cannot properly adjust the settings to their load's actual needs)

"Next thing they will be encouraging you to hook your DW up to the cold water line instead!"

While maybe not so much in USA but cold fill only dishwashers have long been on offer all over Europe. Then again as with washing machines were speaking of homes that always have 208v-240v power connections as standard. With such heating power available dishwasher have no problem heating water from cold to hot or whatever temp is required. In fact given small amount of water used in dishwasher cycles compared laundry the former can reach temps comparatively quickly.

Allowing for heating cold water to an exact temp means a dishwasher can do china and crystal at lower temps, but still also heat to higher for cruddy dishes and or pots/pans.

Well that's good to know; since P&G tried once to get Americans to use cold water for laundry (Tide Cold Water) and it bombed.

Unless P&G has changed Tide CW formula the stuff works best between 90F and 100F. IIRC when Consumer Reports tested Tide CW back in day they found it gave best results in that range.

Tap cold water in USA varies across the country by geographical location and time of year. What washing machines with heaters or other systems to determine water temp consider cold varies as well. 86F is usual number IIRC, but again things can vary.

Cool definition

Most modern machines actually discourage the use of tap cold IMO.

Most digital interfaces try to make you use cold (basically controlled cold) over plain tap cold.

That's the one thing ATC has going for it: You do get the same water temp every time, regardless of what the connection is.

Temp wise, 90-100F is basically the go to for most any washing.

Best for enzymes, good enough for tensides.
For bleaching and hygiene, higher temps are better, but not needed for much more.

I do think though that many target temps for Normal cycles at least isn't really that optimal.

Quoting the famous Samsung manual line, their warm is swimming pool water, their hot is bath water temp.

That is vague, but guestimating is possible.

Hot should be right around 95F, warm anywhere between 70 and 85F.

Given that, I would guess controlled cold is aimed at 60F.

And I'd dare to say most other brands aim at the same temps.

With the typical 4 or 5 temp settings excluding tap cold, a not unreasonable shorthand might be - for the energy label cycle at least - 100F down in 10F steps.
So 100-90-80-70-60 or 100-85-70-55 or such.

Funny enough, Whirlpool just ditched most temp labeling a couple of years ago.

They just label hot and cold on either end, and give you like 6 or so LEDs to select from.

Possible they even just eliminated tap cold on the FLs, but not sure about that.

Chuck - it is,  Novotronic 1918.  Love that washer.

 

I don't even keep the machines awaiting restoration set to anything but Hot water (and warm rinse)  

 

The Cold Water Cascade box is from years ago, our own Nate in AZ created that in a similar discussion about cold-water washing/dishwashing.

cold water

Here we go again with the "washing everything in cold water" mantra. I'm sick and tired of it. If I want cold water, I only do it on dark items. Sorry not sorry! Nobody can tell me how to wash my clothes.

"saving the planet"

I think we should all give up washing our clothes and taking baths. That will save our planet, even faster. We are not running out of energy on planet Earth. Energy is neither created nor destroyed.

I won't purchase a washer, vintage or otherwise, unless it has a warm rinse option. I hear that dermal allergies are on the rise. It is no wonder, we have washers that don't rinse properly and leave detergent residue on the skin, and now we are to use ineffectual detergents in cold water.

I am not that submissive to let the Government, nor industry, tell me how to do my laundry. That is not the purpose of either entity.

no more warm water

Unfortunately, this no mor warm water washing trend is still ongoing. This encourages more bad laundry habits due to this everchanging fad. This needs to stop immediately!

 

[qsd-dan]

Guess I have to eat crow on post #3. I use powdered Tide detergent since my favorite one was discontinued and there are not any good powders around anymore. Also, most detergents (especially liquids) reek of scents and this one does not.

 

[daveamkrayoguy]

What then will my water heater be used for?

Or is it part of the banning gas appliance ban, that I'll not have...

I just want to say I can not take your picture out of mind since you posted it on 3/18/2021. That is so cool/fascinating. I never knew 50s washers only offered hot or warm. I also bet those water valves were true 50/50. Are the rinse cold or warm?

@gansky1: Do you have more pictures of that front load washer? I like how the temps are built into the dial.
