Miele w4840 and detergent dispensing
My w4840 has started dispensing both the pre-wash (heavy soli) detergent and the main wash detergent at the same time (both in the pre-wash). I am wondering whether I unintentionally changed something in programming mode which created this situation. I have a vague recollection that this functionality might be desirable if one has hard water, but in looking through the programming mode, I can't find any option for "hard water" that I might have accidentally switched on.
Does anyone have any ideas about how to stop both dispensers from releasing detergent at once? I have just started an extra white cycle with heavy soil, extended, and sensitive selected, and it is definitely releasing all detergent in the pre wash.
