If electronic sensors belong anywhere, it is in the rinse water. The military has refined sensors for taste and smell but a simple optical sensor in the final rinse would function as an excellent babysitter..this way no matter what size load or level of dirt you have the results are consistant. It's all rinsewater now days. Good question.
I wash cold exclusively, have'nt gotten around to refining my wash method, why bother since I still have 2.5 gallons of cheap powder left. 2 words - Tide cold powder.
The staber is rated at 18 pounds, I got it because it is a full size machine and I can wash enormous loads to be effecient since washing 8 versus 16 pounds DOUBLES every (every) expense associated with you washer. Therefore and due to the smallish staber tub, and because I wash cold exclusively, I have to run the tightest ship possible to still get results. Here is how to do it with any machine...
Sure this machine takes 18 pounds in a pinch and is pretty effective due to the diamond tub shape, but with those loads one must use a prewash, which in the stabver functions as an extra rinse, but even here over time clothes will/might get dingy. (keep in mind i'm a bit of a complete slob, my laundry is absolutely filthy compared to average, just fine dust/dirt mostly and sand/oils)I do'nt really seperate whites entirely from greys also etc.
Therefore, the clothes were getting dingy overtime.

Because lack of hots means I do not set stains, if the clothes become dingy, I still have the option to erase the dingeness in the future. (I also air dry exclusively since incidently drier heat sets stains) over *time* oils - stains inevetably come out: I prefer this option..and by using multirinses I *now* have cured the dingy problem, and clothes last longer. I also use sunlight as an extended disinffectant I now sun dry everything.

So to answer the cold question is simple and it involves 2 things being using the best *powder* and 2 watch your rinse water.

Washing without seeing your rinse water is a shot in the dark I could not see doing it in any other way, so early on I modified the Staber so now I can check rinse on the fly. (a simple expansion chamber in the out line will work) When/if you elect to do it that way you can just dump the rinse water into a jar, in the beginning I would use up to seven rinses/jars, and these I photographed for refereance. It gets to a point where all your left with is dyes, so the water will have be a blue grey cast (do'nt go overboad on rinsewater!) This I proved by capping the jars tightly and letting them sit for a week then smelling them. I found a prewash with 1-2 extra rinses is about right. (remember I am using 16 pound fiiilthy loads)
For comparison, the Staber does a prewash with 1-2 ounce soap, drains, wash with 1-2 ounce more soap, drains, rinse one, drains and rinse 2, drains. So I count that as 4 rinses. On top of this, I just add rinses till I'm satisfied, and this means on wash day I hang out doing work in the garage where the machine is so I can babysit when it starts rinsing. this way my wash is always on target.

Before this, the staber at one point in the height of my filth which for me is always midsummer developed a bad smell. I did not attribute this to mold or build up Since the outer tub is still shiny, but to rinse water which sits at the bottom of the machine 1-2 inches deep. (this I *like* to prevent hard water deposits and salt concentration, and dried muck build up and oxygen resulting in rust and the inevitable outer tub leak) After one small wash the smell vanished. It's all rinse water now days.

The staber incidently has a timer dial which allows me to program any one of a gillion different wash combinations, and It does'nt need a mondo hairy and vulnerable elecronics board.. some timer dials by the way only turn clockwise, this one goes either way which is ideal. I can do limitless rinses, in summer I use all the rinse on plants anyway. For a given amount of time, the staber also has the most agressive wash/rinse for a given tub design, which is the true measure of a good washer, Consumer Reports for instance does not take tub design into account, they just check results for a given electric program, which does'nt tell you which machine is able to pull the most efficiently for a given time when programmed optimally, which translates to great variance in expense and wear; commonly refered to as a lack of simple common sense on the part of CR.

Washing always involves balance, programing from the start is barking up a comprimised tree since the animal is usually moving. You end up with either too much or not enough, usually to much.. the manual timer dial and the ability to open the machine any time is the only way I would ever wash.

Many machines offer any number of extra rinses, the staber dial however allows me to adjust on the fly which is the best way, this way the inefficient redcoats are never coming.. want a worldclass machine program it to adjust rinse water based on an electrical sensor, but it still wo'nt beat user interface.

This machine is also everest of gentle whith the most delicate item being pillows comforters. While the staber has a very good inner tub approach, on the other hand a 4800 with 4 cubic feet will I think match or exceed on average the staber 2 cubic feet approach, definately when using comforters, when washing 16 pounds I'm not so sure, also because the staber tub has the advantage of generating air/suds with it's splash, which has been found also by the japanese to be a big advantage in their Panasonic washers together with thier foam generators. The Staber for instance has a week spot in the center of say a big flannel sleeping bag, so as in any front loader one should load such an item so the part you lay on faces the outermost tub peripheral. (I tested this phenomena using ketchup) The 4800 will wash a big comforter much better than the Staber I would think. This is the main reason the 4.2 cubic foot LG is on top at CR, it solves the staber ketchup problem, but the trade off is weight/mass. I've washed my sleeping bags some 70 times, they are lasting veeery longtime and the wash is definately sufficient versus the laundry mat. I even keep the wash/spin on normal high speed. (do not wash a comforter on delicates in a staber! is my opinion) Bottomline the staber offers a hidden cost saving/operational advantages that I prefer by a wide margin due to the tub design, even if wash results (at 16 pounds) are not as good as a 4 cube foot machine.

..on detergent it's easy, go with Tide coldwater powder, it won a shootout out of around 30 detergents at CR. Cr found powders to be superior, tide cold liquid was way down on the ratings.

Also since I wash cold, and with powder, I learned early on to dissolve the powder first. Critical. I place the powder in a glass jar with a half cup water and microwave and shake it, add more water, shake again. If I do not do this, the aggresive wash of the staber tub forces the powders into the clothes before it ever dissolves and it gets trapped in there when using full loads that ca'nt breathe as ideally. In the miel machine,I imagine using *my* powder would cause some of the powder to sit at the bottom of the *outer* tub undissolved, (, being sams club detergent) and you would run out and by some liquid persil to get clean clothes. This is because circular inner tubs as they spin cause centrifical force to hold water to the outer tub - (tiny tub holes can aggravate this) The Staber has big pencil sized holes, and because it doesn't use a space eating window, gets by with only 2 cubic feet of tub space. This is one reason many ahorizaxis machine manuals do'nt recommend powder, only HE. The tide cold water I suspect will not need to be dissolved before hand in any machine. It's good stuff.

Lastly, on the staber anyway, I can use much more powder than the manual states and still have the machine spin out full speed and not suds lock since the machine breathes while shut and running, ulike machines with a sealed glass windows, and the inadvertant sensors needed to keep an eye on suds/spin speeds. I take full advantage of this by loading up to 5 ounces of powder into the prewash versus 2 ounces in the pre and 2 ounces in the wash which is how the staber is originally set up. Not sure if this is better but that's what I do. This also allows me to forfeit the stupid automatic detergent loader. With the Staber I can open it up and fiddle around at any given time - even on locked door by pulling out the timer and waiting 2 minutes. Some of us have hard water and it varies day to day, my water needs more detergent do to the hardness so the staber I think is a real advantage here.

One last note, my pillows and comforters I wash every to weeks at most, and sometimes the wash water is brown, but I never need prewash or extra rinse with these ultra light items. (or it could be the fabric is producing less dye)

I decided early on cold wash is the way to go, yes I know all about effects of cold and hot an certain varied protien or not and or saturated temperature activated oils stains etc., but I think in the real world it's not so cutdry, everything gets jumbled in the wash and if clothes become dingy it is a smorgashbord ding that can become set plus hot water has an effect on wear and expense.

Not using drier is just another part of enhancing my cold wash performance, alittle detail here alittle detail their. The drier heat can set stains. I do have lint remaining on some fabrics, some fabrics are notorious for holding lint, but most of it pills into clumps that can be removed by hand especially with longer tumbling. As for wrinkles I simply fold the clothes when it is hot from the sun, after that body heat and movement does the rest.

..but yes omitting the drier is just another part of washing cold.
Getting the details right can produce results when cold washing.. (to save timemoney ofcourse) It takes just as much effort to do it accurately as not and in this case much less when all is said and done. I recently set a world record 57.96 mpg in a stock Honda Civic non hybrid EX, and everyone thinks I did it with a tail wind on a test course at an average speed of 26, no, you do'nt have to suffer to get results. To rattle your brains I did it at an average freeway speed of around 70 mph. I realize this took alot of typing but once you get it down coldwater washing works. When I set the record it was on freeways and 30 percent city in cool (hot air is more efficient) still air, among other things, I would accelerate to 80 or so on down hills and flick it into neutral; after first ofcourse making sure the wheels/bearing/brakes were frictionless, so I no did'nt get there late afterall. I used speed memory basically - commonly known as energy retention in aeronautics, as in airplanes also in cars, weight (ballast) suddenly becomes an advantage. completley backwards to conventionally thoughtout physics, which says lightweight and lower averagspeed for efficientcy. it is the same with coldwater washing. The other tip that I havent tried yet for cold washing are the oxy bleaches which is how many hospitals are doing it.
It is not always what you think will work but what actually does - hot might still get you cleanest I agree (currently)

Cyberspacer,

In Europe the ideal temperature seems to be 30-40*C for general laundry, with some people (only some nowadays!) reserving the higher 60*C temperatures to get rid of dustmites, bacteria etc on towels/sheets/kitchen linen.

I use a coloursafe detergent on everything but whites and sometimes lights, and my colours and darks have never been so vibrant and true, especially compared to before last year when I never used to bother with coloursafe detergents and hence had faded darks!

For your dressy clothing, I would utilise the delicates cycle - despite being gentle it is very thorough on delicate loads and I've had great results with this, even on woollens... I tend to use it now instead of the Woollens Handwash cycle

Hope this helps!

Warsher, a pity you spent so much time typing your blog, as I can't see any sense in it at all. And I have to correct you - Miele machines flush tap water into the sump first to activate an eco valve before before flushing in detergent - preventing detergent waste, hence detergent doesn't merely sit in the outer tub, and is fully utilised. The window doesn't eat space either - it's there to keep clothes in the tub, and doesn't protrude into the tub space at all - only the gap where the door seal sits that exists between the front of the inner drum and and door opening - which is outside the area in which the laundry operation takes place!

Conversely, electronic frontloaders can add as many extra rinses as you want too by using the seperate rinse cycle... which is identical to your "limitless" extra rinse cycle on the Staber. Your typical cycle only consists of 2 rinses, not 4 (if there is detergent added to the water then duh! it's a wash...), and with my Miele I don't have to babysit my washer yet I always have perfectly washed and rinsed laundry, just by turning the dial and pressing start! (And a usual dose of my powder - but without mixing it in a glass first perhaps I must be doing something wrong!)

This is one reason many ahorizaxis machine manuals do'nt recommend powder

Funny, seeming as powder and powdered tablet detergents on the UK markets far outsell liquid and liquid tab variants...

I have a Miele from 1990/91. Because I have a dustmite allergy I try to wash as much at 60*C/140*F. More delicate stuff is washed at 40*C/105*F or 30*C/85*F. I would hesitate to wash at a really cold temperature. Problems with dissolving detergent could occur (I wash with almost powders only).

I agree with aquarius2101, for most purposes the 30-40C cycle is sufficient. This cycle is normally considered to be a cold cycle. Just keep in mind that it is considered to be warm on U.S. TLs and that cold here means actually tap cold. I don't think you can expect good results at all by using water that might just be 45 degrees F. The 60°F cycle is useful for clothes with serious stains, towels, bed linens and the like. It is not a real sanitizing cycle, but it can get rid of most germs and mites. The 90 or 95°C cycle does have a very good sanitizing effect, but many fabrics can't be washed that hot. It is definitely less gentle than cooler cycles and it would cause fading on colored items. If necessary, you can use that cycle for musty smelling dish rags and white cotton clothes, sheets and the like.
And yes, powdered detergent works just fine in FLs, usually even better than liquid detergents.

Ooops, I meant 60°C not F...sorry about that. I can't wait for the U.S. to switch to the metric system...;-)
