Hi all - first time poster, long time reader, looking for some advice from the experts here.
I just bought a "Compak K3 touch advanced V2" to replace an older K3 (not advanced) that I owned for many years. I'm having some trouble with this new grinder: grinding seems to take forever, at least one full minute for 11 grams, with sometimes no coffee coming out at all. I did the same type of grinding with my old K3, same fineness (for the same espresso machine, La Pavoni pro), and even though I never timed it I can't remember it taking so long.
I mentioned this to the seller and showed them a video, and they are telling me that this happens due to the single dosing (the hopper starts empty, I weigh 11 grams of beans and put only that amount in the grinder). According to them, these grinders aren't meant to work like this, as they need some pressure from extra coffee beans on top of the dose being ground.
This seems weird to me, as I used my old K3 in exactly this way for about 10 years, always single dosing either 7 or 11 grams.
Am I wrong, and is single dosing in the K3 not possible (so was I just lucky with my older K3) ? Is it normal that I need more than one minute to grind 11 grams of coffee ?
Would greatly appreciate some advice, thanks all!
