Regarding pressure readings of 12 bar, wouldn't that be a problem that should be resolved under warranty? These machines are reportedly 100% scace calibrated at the factory. If the gauge reads that much higher than expected, it is well outside what I would consider normal tolerances. I don't know what normal accuracy of these gauges is, but +/-30%, makes it as useful as a chocolate teapot (imnsho). If it was me, I'd be talking to whoever sold me the machine to find out where the fault lies. It may be that brew pressure was not correctly set, or has drifted in transit, neither of which inspires confidence. How Breville handle the early problems is something I have been waiting to find out.
