me too, but I was disappointed it didn't really make much difference. Though I did figure out recently I might have just been under-dosing. Really hard to tell on my dishwasher as it provides no instructions on quantities, and the fill lines don't make and sense because while it has the 2 receptacles for the pre-wash and wash settings, they're tiny shallow dimples that both reside in the same larger cavity for power but have no dividing wall between them. So if you fill the wash section up to the minimum (which is a surprisingly large amount), it necessarily spills over in to the prewash section. It also has no recommendations for differing levels, despite having minimum and max fill lines, so I don't know when I would fill to one or the other and then to top it all off, no mention of the concept of filling anything at all in to the pre-wash section, despite having some kind of pre-wash settings and a dedicated spot in to which you'd pour the powder for pre-wash. It also makes no sense for that pre-wash section to be there, because in the video and on older dishwashers, the wash and pre-wash recepticals have their own doors that flip open at different times, hence pre-wash, but on mine, both of the little indentations in to which you could pour powder are in the same cavity with the same door. It's weird, they clearly didn't expect anyone in this day and age would still use powder even if it's theoretically better. I've been making up a quantity to put in to the pre-wash, assuming it helps but really no idea.
