No idea what Err2 means Im afraid. Id say its time to give Breville a call in the morning. They may ask you to help further diagnose by doing something like what Phil describes below so may help to be by the machine when you call. Lets us know how you go, Id also be interested to know what it means.
Info on Err1 from Phil posted on another forum.
http://coffeegeek.com/forums/espresso/machines/560878#560878 This code just shows there was potenially a general error. Please follow this procedure to get more detailed info: With the power cord plugged IN & turned ON at the wall socket. Machine OFF Press & hold IN all four buttons simultaneously, Menu, Arrow Down, Arrow Up, Exit. While holding them all down, press the Power button The LCD will now be in the Service Mode There will be a single, double or even triple digit displayed. This is the number of shots over 7 secs, divided by 10. So if you had 12 on the LCD, this would mean you have pulled 120 shots longer than 7 secs.Press the Menu buttonYou will then see a four digit display XX:XX make a note of the 2 digits to the left & the right of the colon.Let me know what these numbers are & I can tell you if you have a problem or not. Press the Exit button at any time to exit service mode & go back to startup mode. Cheers, Phil
