With all due respect, I asked an important question. Does the Krups have an over-pressure valve? I'm not aware of it. I don't see water streaming into the drip tray, and I don't see any way that water can go back into the reservoir.
If there is no over-pressure valve, then I am getting 14+ bars at the puck and I need to grind super-fine to avoid a 10 second extraction.
BTW what is the difference between "fines" and "dust"? According to the TGP graphs I've seen, all dust would be categorized as fines.
I am keeping an open mind but these are serious questions, and I'm not convinced that I should spend a buncha bucks on a couple of rotating burrs. Part of my open mindset includes the possibility that, consistent with my experience with preground coffee, my grinder is not the problem, site religion aside.
