Our machine worked fine up until a few months ago. Troubles started when it stopped grinding the right quantity even though it's set to max quantity and 2 cups. It looks like it's grinding very fine, almost like flour. I don't recall if it was always grinding this fine. We have always used the Dual Wall filters with the same settings on the grinder side. Then soon after, once we put the filter in place and start the pomp, the pressure gauge goes almost to the max and hardly anything comes out. When the filter is in with no coffee in it, it pours fine (when rinsing for example). Foamer works perfectly. I've tried cleaning it twice with vinegar, cleaning the grinder head, doing a "Clean me" routine.... no go. Help, I miss my good coffee!
