Miele W4842

[mieleforme]

First I’d like to say hello to everyone, I’m new here. I never knew there were others out there like me who cared how a washing machine worked. I’ve always been into things mechanical. I remember when I was about five years old I would sit in front of my Aunts washing machine ( A sears front load in the 80’s?) and watch that thing for hours. Everyone thought I was strange, and maybe they were right, but now I know I’m not alone. Hello again now on to my question.

I’d like to know if anyone has firsthand experience with the W4842 or any W4800 series Miele washer for that matter, pertaining to connecting it to cold water only. I have heard that starting a wash cold and letting the washer do the heating is better for stain removal. The theory being that protein based stains are removed better in cold water, hot water may make them set in if not removed before heat is applied. I don’t worry about how long it will take, I just want to know if the Miele will in fact wait until the target temp is reached and proceed as usual. Does anyone know if washing this way is really better? Sounded good and I thought I'd try it when my machines arrive.

Well thanks for the help I can’t wait until my new Miele washer and dryer get here. Any video or picture request you can send my way. They are replacing my Neptune set pictured bellow. The bearings are going out in the washer and I used this easy excuse to replace them both. They are about 8 years old and the washer says it has completed 5500 wash cycles. WOW!

Hey there...I have a Miele w4800 washer and the t9800 dryer. You can hook up the machines to cold water but you would have to use a Y adapter. But why would you want to other than the stain thing? I have mine connected to hot and cold. The washer doesnt take long to reach the target temp of the cycle. But one thing you have to know is that certain cycles lock you into a set range of temps. Take Extra White cycle. The only options for temp is very warm or hot. The wash cycle HydroMatic system is different from a Normal cycle. The water level is a bit lower in the Whites cycle compared to a Normal cycle as well.
One thing I have to say that with stains this washer will power out stains better than any washer you may have used in the past. The drum plays a big part in it. I find that even with heavily soiled loads that I dont even need a prewash or Extended wash.
The dryer I will have to say is very good but be ready for it to be louder than what your using now. Its no slouch drying and clothes come out without static and not shrunk. No matter how I try to shrink something in that dryer it wont let me. The sensor system the dryer has is top notch and it will shut the dryer down within a minute if there is nothing in the dryer.
Oh and another thing DO NOT USE DRYER SHEETS in this dryer. It will clog the lint filter.
Here is a pic of my set

Hi! another W4840 owner here....

just a friendly reminder, you're expecting too much from a 1000W heater....

Welcome and isn't it a great feeling to discover you're not alone at all? Front loaders is what got me hooked on washers when I was 18 months old. I've been reading forums on another site all about these Mieles. I'm really interested in them. There's one things I've seeen mentioned a time or two about the 4842 (and I"m not sure if it's true for the 4840), but supposedly there is some sort of turbidity (soil) sensor that measures soil/dirtiness of the water when the heavy soil option is used (which causes a pre-wash) and I"m assuming a cold pre-wash. Anyway, this sensor, if it doesn't measure a certain amount of dirt in the water, will skip the drain of the pre-wash water and proceed into the regular wash cycle, which would then cause the cold water to be heated all the way up to whatever the target temp is--be it warm, very warm, hot, or sanitize. Don't know if you're aware, but to get a better energy star rating for the U.S. market, the heater is not engaged at all on the normal wash program, regardless of incoming water temp. You simply use the custom program and select spin speed and wash water temp you want as a substitute cycle for normal.

Thanks for the info man!

I wanted to try to use only cold water ( I do have a Y adapter) for the enhanced stain removing I hear it adds based on that theory. I guess I could always do a pre wash, I’m sure that’s always cold, but I wanted to try hooking it up permanently to also get the full benefits of my “laundrypure” system ( the UV Light device you can see mounted behind my washer and dryer, link bellow ) that only uses cold water. In the past with my Neptune I couldn’t do the all cold thing because that heater didn’t get very hot and I didn’t think it would ever be able to get up to temp with such cold inlet water. Eco quest the maker of the Laundrypure system says you only need to use cold water and no detergent for washing everything using the laundrypure, I call BS on that idea, my whites are getting washed at the hottest temperature I can get and every load will have some detergent. While I do like this system, the operation of my new Miele is top priority. However, I would love to get the best of both worlds from these great devices.

Thanks again for all the info!

I am a little disappointed that we have the smaller wattage heaters here in the U.S.A and these machines don’t get up to the 200 degree F range. However being a power plant operator I don’t think it’s the limitations of our power system (120 VAC) as much as it has to do with energy consumption. Electric heating elements suck up a tone of power. Our lower voltage system it is much less efficient that the European (220vac) system for this type of energy consumption. I will probably just hook it up normally and trust Miele has made another out of this world product that will make me forget about everything.

That is good information to know about the water quality sensor, I’ll have to pay close attention to that!

Interesting concept...

Didn't Samsung have an issue with their Silve Nano technology washers recently?

Yes i think Sam Sung did have an issue with the system they had. I have to say I like the laundrypure. Even though I don't think you only need to use cold water and no detergent as they say. You defiantly use less detergent but i keep the wash temperatures the same as anyone would. I can only imagine how much less i may use in the Miele. Clothes feel and smell much cleaner with this thing. For example we inadvertently left a load of laundry in the washer for nine days as we went out of town. When we discovered the forgotten load it didn't even stink. We put it right in the dryer and all was fine. Before if clothes got left in the washer for more than a day they smelt gross. This thing is great!

turbidity sensor and "heavy soil" option

Hi Bob,
are you sure about that ? I'm aware of turbidity sensor in Miele DWs on the "automatic/sensor" cycle . They indeed skip the prewash drain when there's no need of new water.

But in washers "heavy soil" (actually "prewash" in other mieles elsewhere in the world) option requires detergent in both I and II compartements. So if it skipped prewash drain , to flush the main wash compartment (II), the machine should fill again anyway. But a short fill often isn't enough to flush, expecially in case of low pressure.

Go figure that in case of low pressure euro mieles have a "hidden" option to flush both compartments I and II during the main wash fill, so that one can divide the amount of powder in the 2 compts that will be flushed better

No turbidity sensor in Mieles. It does have a rinse sensor, which is essentially the temperature sensor. However, the sensor rinse is disabled on the US machines via the software.

For protein stains, I'd either run a pre-wash or you can turn the hot water tap off and the machine will switch over to cold fill after a few minutes.

Turbidity sensor in Miele W4840?

My W4840 sometimes drains after prewash, sometimes not. I think it's correlated with whether the load is really dirty. Why would I want to use prewash on a not-so-dirty load? Well, I wanted to use it to rinse household cleaner out of housecleaning rags. But the machine went directly from prewash to main wash, with just a short fill which presumably flushed the main detergent dispenser. So the prewash is useless for this purpose, and I have to do a Quick Rinse instead.

 

[askomiele]

Hmm

I would say, tape that sequence and let us discuss it here, or just make a whole study about it ....

 

[catalystboy]

Congrats on your new set!

by the way congrats, Miele is quality no doubt, i have a capricorn. great suction.

 

[nmassman44]

I had to think about the Capricorn comment for a second....then realized it was for a Miele canister vac. I have Miele Ariel vac that I just love. Worth the money.

 

[appnut]

Suburbanmd, thanks for letting me know I wasn't loosing my mind seeing if i remembered such a concept being executed.

Does anyone know if the prewashes are cold fills? If so and the load isn't all that dirty and skips the drain and starts heating for awhite load, then it's starting with cold water and heating to hot just like Mieleforme wants.

 

[somonica]

if you do prewash without select extended wash...

prewash in W4840 does always drains, spin and then fill from the main dispenser....

its done all that while the display still say "pre-wash"!

after 15 minutes or so, then it will do a short fill and change the display to "main wash"....

may be Miele hired some ex-M$ employees to program our machines....

 

[somonica]

pre-wash use the same temperature setting as the main wash...

 

[brisnat81]

I'm interested in the Prewash on the US machines being the same temp as the main wash. On the euro machines the prewash is cold, it drains with no spin and then refills for the main wash.
