AM, I think you are right, which is why I contacted Breville today and provided the following information on CS, and now here. Having had several discussions with Breville regarding the higher than expected gauge readings on some of the 900 series of machines, I have some further information from Breville. 1. The initial run of 900's were all calibrated using a scace device to 9 bar whilst in production, plus or minus .5 bar. In the real world, some machines that were calibrated this way gave high readings eg. 12 bar. 2. Machines that are now being manufactured for here and the overseas market, are being calibrated during production with a block filter instead of the scace. They will read either on or close to 9 bar in the real world. 3. If you own a machine that read high, then: a) It will not harm the machine b) It can be adjusted to 9 bar and is approximately a 5 minute job. No parts are replaced during the process. c) Breville are ensuring at least one major service centre in each city is capable of performing the work. This is already in place in Sydney and Brisbane with others to follow soon. Please call Breville if you have a machine that has a high reading and you would like to arrange to have the adjustment made. And please accept my sincere apologies if I misled owners or potential buyers in any way. FWIW, the machine I have at home reads high, yet makes great coffee. Cheers Den
