Miele W4842 - Profile Wash How-To

15 years ago

Believe it or not, the Miele W4842 does have the ability to do a profile wash. However, it's not something that can be selected from the myriad of buttons on the front panel. My definition of "profile wash" for purposes of this article is setting your machine to a target temperature and the machine fills with tap cold water that is then gradually heated over the course of the main wash program to the temperature you've selected. This allows stains on your clothes to be exposed to a wide range of temps, starting at cold, for maximum stain removal.

Step 1 - Enter the service programming menu:

  1. Open the door of the machine and the lights will come on.
  2. Press and hold the START button while you close the door.
  3. When the START button begins flashing rapidly, release the button and press it five times quickly in succession.
  4. If you are successful, you will see the programming menu magically appear!

Step 2 - Change the water intake option:

  1. Scroll down to the "Water Intake" option, then hit OK.
  2. Select the "Cold" option ("Hot + Cold" will be the default)
  3. Once you're back to the main menu, scroll down and select Exit.

You have successfully programmed your W4842 to exclusively use the cold tap for all water intake. If you select a heated cycle and avoid the "Normal" unheated cycle, the machine will engage the heater and raise the temperature of the water to the target temperature while it washes. I verified this by using both the Wrinkle Free and Custom cycles set to HOT. I confirmed that the initial fill of water was tap cold, but over the course of the wash I was able to open the door and see lovely, hot and steaming water in the tub. Eventually the machine locked the door due to temps in excess of 130F - as stated in the user manual. This confirms that the water did, in fact, reach at least 130F with an hour remaining in the cycle. It's reasonable to presume the water had enough time to go from tap cold of about 60F to 140F over the course of the main wash. The door glass was quite warm to the touch just before hitting the rinse cycle, and since the glass is well insulated with an air gap the temperature inside the drum was substantially higher.

What this will do:

  1. Remove a wider range of stains, and prevent some stains from setting.
  2. More efficient to heat water at its destination rather than heating at the source and incurring heat loss on the way to the machine.
  3. Reduce shrinkage at higher temperatures by gradually increasing temperatures rather than initially shocking the fabric with hot water.

What this won't do:

  1. You cannot use anything but COLD water in the Normal cycle, since that cycle does not engage the heater.
  2. You will not get the full benefit of the "Clean Machine" cycle, since that cycle wants very hot water up front.

In order to use your Normal cycle with anything but cold water, or to use your Clean Machine cycle to full advantage, you will need to go back to the service menu and re-select "Hot + Cold" fill.

Since Clean Machine and Normal are probably the two most seldom used cycles on the Miele, the loss of full functionality of these cycles may be an agreeable compromise for some to get a true profile wash in other cycles. I've missed having a profile wash option since I replaced my Asko with the Miele, and now I feel like I've been able to get the best of both worlds.

    Wow, great work Sstava!! How'd you figure this out? I do not use Normal very often anymore, but 1-2x a month, I do use the Clean Machine cycle (it's fun to watch) and it seems to do a kick ass job!!

    This is how my Asko worked on all cycles regardless of temp setting, and I'm so glad I can get back my European profile wash! Now no matter what temperature I select, I will always start with cold and go up from there. An enzymatic detergent works best in a profile wash, as the majority of wash time is spent in the enzymes' "goldilocks zone". Enzymes can also be pushed to work at higher temperatures than they would normally if the surrounding water temperature rises slowly. An enzyme that would completely denature if hit with 120F water may very well tolerate it if taken to that temperature gradually.

    I just finished a load... squeaky clean and all stains removed at 105F. Thank you Persil! :)

    Dig your instructions, Sshrivastava. I'm down with experimentation but wonder if the Miele police would give me a hard time. I never did read the warranty with all those rules and whatnot.

    There is certainly no harm in experimenting, right? I've read that a less complicated way of getting a profile wash with the W48XX series is to simply select the Heavy Soil option. This is supposed to do a warm pre-wash, drain/spin (some cycles do not spin after pre-wash) and then a main wash at the actual temperature selected. This will probably give us most of the benefits of a profile wash without fiddling with hidden settings.

    BUT FIDDLING IS FUN! :)

    Great information, many thanks!

    Yea... Nice work!!!!!!

    Almost embarrassed its take one of us this long to figure that out. Now I'd be interested to verify if it does reach absolute target temp and how long it holds that temp before continuing the program. My tap water is freezing balls right now. A Sani wash will defiantly take longer than normal, at least it should, if it performs as it should. Humm, time to experiment.....

    I know that Bosch does a "profile wash" since it fills with cold and heats to different temps depending on the stain.

    Stain Removal Option - Remove 14 different everyday stains with just a touch of a button. Different stains require different temperatures to treat them, so the Stain Removal Option incrementally increases water temperature to target each stain at the optimal level. Select with any cycle and easily remove, grass, red wine or tough grease stains without pre-soaking.

    Is this something Miele could add by updating the software??

    If this is such a great feature would the Bosch be a better machine?

    I believe the Bosch Vision 800 has all the features of the Miele plus a few - heats to over 170 deg F, has a simple profile wash option, and is a true h-axis machine and not tilted drum like the Miele. Also has 10% larger capacity than the Miele W48XX series.

    I think from a feature standpoint, the Bosch can't be beat and addresses all of the Miele's shortcomings. With regards to build quality, I couldn't say. I've heard a few horror stories here about Bosch, but you get that with any brand.

    sshrivastava ... ahhh!!! I know, this has been my dilemma for awhile now. Miele definitely feels more solid but I like the features on Bosch. If I could marry them together - nirvana!

    I have the opportunity to get a new W4842 40% off right now but I'm paralyzed. I keep reading and re reading all the info and nothing is pushing me one way or the other. One day I'm Miele, next day I'm Bosch.

    While I love the solidness of Miele, I'm curious why the W4XXX series seems to be missing features that others have (even the Miele more Euro washers).

    Then I question how important those features are. I do think the profile wash makes sense - what to do ... what to do ...

    livebetter,

    Being a fellow Canadian, and if you can tell me, where can you get the W4842 for 40% off?!?!

    Thanks,

    WR, I take it you would go for the Miele over Bosch?? :)

    I don't know if your name infers you live in the Waterloo, ON area?

    There are two locations in the GTA that sell out of box stuff. Some just has no box but in mint condition, some are "b" grade meaning minor blemishes (I've seen them and some of them you'd need a magnifying glass to see), some have more severe blemishes. It's hit and miss but I keep my eye on them weekly.

    Just to clarify, the Miele Unboxed store is located at the actual Miele warehouse. It is part of Miele. I'm not sure MTC is related to Miele but they must have a deal with them. Miele delivers the items directly to MTC from the Miele warehouse.

    Go and compare the Bosch to Miele in terms of build quality, feel, robustness, etc... Even the latch on the Bosch door is plastic. Buttons, door trim is all cheap and flimsy plastic. Rubber door boot looks deformed and oddly shaped. Selecting wash cycles yields a cheap, thin feel...almost like it is going to break in your hand.

    While I really appreciate all that Bosch (and Electrloux) offer in terms of cycles and goodies...it is a WASHING MACHINE. Get the Miele. Trust me, I've tried a few other brands...and will NEVER leave Miele again.

    In terms of blending the best of Miele and Bosch...an amazing Swiss company is V Zug! You can read their UK website, if you do not speak or read German. If the USA or Canada sold V Zug....Miele would have a BIG run for their money!!

    Thanks Larsi! I know ... I admit Miele seems more solid but I also feel it could be better in terms of features. The Bosch Vision 800 is a little more solid than the 500 (some metal vs chrome etc ...).

    The door seals I've seen did not look deformed but they were in machines that had never been used.

    I'm not saying Miele needs bells and whistles but I can't understand why it would not at least do a profile wash (don't most euro machines do that??). Or a pre soak?

    Plus little things like the drum turning after the final spin to fluff clothes a little and a few others are nice to have.

    I've also read (but not confirmed with Bosch) that the Bosch uses the heater is all settings but Miele does not in the normal setting. Bosch has slightly lower temps in the low range and I'm wondering if that's how they get around the energy star thing.

    I really don't think I'll have a machine for 20 years (even if it is still working like a champ). I know me and I'll want something newer in (probably) 10 years. If Bosch gives me the features I'm looking for and will give me 10 solid years - that may be good.

    My fear is I'll choose Bosch for the features and it won't be good for 10 years.

    If Miele runs their 10 year warranty upgrade for free next week - maybe I'll just do it ... the value of that is $569 per machine plus 10 years worry free use.

    My current machine has started making strange noises when the drum is turning and I'm sure it is no longer spinning at top speed so I'm going to have to hurry up and decide before I'm left machineless!

    Thanks again - opinions like this are very helpful!
