My machine did this with the vibe pump, and does it (to a lesser extent) with the rotary. You're just building pressure against the puck, and some liquid sneaks through before the grounds swell and seal a bit. This is basically the idea behind pre-infusion--let the grind get wet with no pressure, the puck seals, and then you hit it with 9 bar or whatever.
Not much you can do about it. bmc On Apr 01, 2011, at 11:15 AM, Cindy Goddard <[email protected]> wrote:
My Brewtus does the same thing (I have the vibe pump). I also have a Vario, but my micro setting is 5 down from the top and macro is on 2nd notch from top. Any finer and it can choke the puck during extraction. I dose around 16g. Have you calibrated your vario? Mine needed calibration when I got it.
