Hi guys, I recently replaced this machine's group gasket with what I thought was a spare Livia gasket (I tried a flat one first, before finding the beveled ones in my drawer). But that gasket leaked and the portafilter bottomed out as far over as it could turn, so I called Pasquini and ordered two paper shims. Installed one, and it didn't make much difference in the leak. Installed a second today, and the portafilter tightens much earlier in the rotation but I still get leaks if I try and backflush. You can see a drip from each side when I attempted a shot today as well http://youtu.be/OzdXkGWq9j4. I spent quite a while scrubbing and scraping the gasket area clean, and would really appreciate any Livia owners advice. I've read some other threads where people mention over filling the basket or pulling shots too hot. I'm using the espressoparts 21g HQ basket with 18-19g of coffee, and plenty of head room below the screen. Doing a 10 second cooling flush and have been waiting 20-30 seconds to pull the shot, just out of previous E61 HX cooling flush habit. Pasquini's only recommendation was to send in the portafilter and group head for testing.

Bump, has anyone ever had to replace a group bell on a Livia or Bezzera? It's a pretty expensive part so I'd really like to find another solution. Thanks a mil if you can point me in the right direction.

Is the water leaking out of the portafilter or above where the bell attaches to the boiler head ??? I would seriously doubt a problem with the "bell". The Livia went through some changes and they made several different gaskets. Pasquini should have asked for a serial # off your machine. If your portafilter is bottoming out-- you have the wrong gasket. Mine would snug up at the 7 o'clock and stop at the 6 o' clock with no spacers. Generic group gaskets will not work. When you find the right oem gasket, bevel side into group when installing.
