I have an 060 without TwinDos. If I had that machine I would have it set to the lowest dose of detergent and act like I had soft water. The water hardness factored into the dose I feel is an incorrect method to determine amount of detergent. The Miele W1's are compact, small drums. I would suggest using the water plus setting at third droplet setting to aid in a good water level. Allergen setting will also gain you an extra rinse on most cycles, and another rinse if extra rinse is used. Do not use max fill for rinses, it is not necessary.

@RoyHobbs Your experience is one reason I didn't want a machine with TwinDos, although you can disable the feature. I like the Miele powder detergents and dose them differently by load type. The Miele powder detergents are amazing at stain removal and very low suds.

i have mine set at 40 ml (1) and 30 ml (2). seems to work fine

some thoughts

9 is not that hard for water 6 is the lowest to look for . anything lower is "too" soft and makes it difficult to rinse out detergent

how do you know that there isnt any residual detergent in the tide washed clothes? Run them without any detergent in the Miele and see what happens

I've been using the Sensitive version. I keep the dosage at 48/27 as recommended but default the soil level to light. By doing this the machine reduces the amount by 30%.

Best way to determine proper dosage for phase 1 is to buy yourself 5-6 brand new towels. Do a rinse and spin and make sure there are no suds. Then start at the lowest dose in the manual. make sure it rinses clean, if it does then up the dose 5 ml. repeat until it doesnt rinse clean. Then back off 5ml.

Phase 2 is oxygen bleach mostly, a binder to prevent mineral redeposit and an optical brightener. it doesnt really cause suds. I would suggest using the dose that is in the manual based on your water hardness. Destaining is oxygen bleaches job. There needs to be enough in the wash liquor mix for it to work properly.

just arrived this morning my top range miele wcr870wps with mtouch display first miele here in italy, I noticed in the first load that before taking the water for the first rinse i earing the twindose pump working like 4 second before every single rinse, did you guys noticed? even because I have soft water too I setted on soft water ml but still making a lot of foam, I reduced to 40 and 30ml and still making foam... so i guess that when i earing that noise in the rinses it dosing again detergent for some software bug...? nobody noticed this? may be this is the problem so im upset because i changed 3 brand and i sended back because they had problems so.. i invested in the expensive miele but i still have problem i really can't take no more. monday i will call miele service and asking about...

edit.. the noise was caming from the detergent drawer is the inlet valve that changing sector where to spry water i guess.. but the way i still struggling to set right the twindose... i setted now to 30 and 20 and seems to low, but i washed a jacked only befor this cycle and make enogh if not to much suds... it should dosing according to the weight of the laundry not standard for every cycle. also i received a notification in my phone that say the duration of the cycle been adapted to the load... with automatic plus may be it took off 5 minutes no more... i complained at miele that the cycle never reducing the time even if i wash few kg and they have to came to check that everything is ok because it is suppost to reducing the time. but in cotton o other cycle it never did even washing 1kg in 9kg cycle

i adding a new comment trying to helping, repair man from miele camed at my home, and i think my machine have problem with the automatism quantity that determinate how many time water and energy usign accordingly to the weight that i wash, also it never reducing the time even now that he activate this sistem that we don't know way was deactivated from factory, but notghing changed still overdosing... so if you have this problem is not the rest of detergent build up on your clothes... your machine have problem so call miele and let them fix it.
