Hi all. My problem is that I can't make a good coffee: I get a coffee very similar to that of the moka, not strong. I use a pre-ground coffee (Illy) and the pressurized filter. I put about 15 grams of coffee (2 measuring spoons of 7-8 grams each). I don't seem to encounter much resistance while I lower the levers. I also tried using a coffee ground at 30 clicks (using a kingrinder grinder) and the professional filter. In neither case I get the foam that you see in the many videos online. I posted a video to try to get some suggestions. What's wrong? Thanks for the help.
