      And it is not even 10 deg C, closer to 5. Scale is Fahrenheit.

        Hello Pete,

        One of the risks of buying a second hand machine is you never know the history of how it has been looked after or not, as may be the case.

        The BZ10 is normally a very good and reliable machine with good reviews and support on this forum.

        We are an authorised Bezzera seller and service agent. If you would like us to look at your machine for you feel free to drop us a line or message

        Regards

          Nice!
          May I ask how do they compare in terms of noise when you turn them on (and the boiler fills up) and when you pull a shot?

          I am about to pull the trigger in one of these two, and I would like to now if the rest of the family would hear the machine at 6am if I use a timer to warm the machine up.

          It is a pity that the PL62 takes longer to warm up than the BZ10...

            As for the pump kicking in at 6am....you can 'prime' the machine the night before so that it's only the element making any noise the next morning. By this I mean after the machine has cooled down for several hours - briefly turn on the machine for a few seconds and wait to see if it 'needs a drink' by virtue of the pump kicking in to fill up the boiler to the level required. When you start to hear the element come on - turn the machine off and it will be ready to go for the morning with no pump kicking in at 6am.

            Agree with ******'s suggestion re the timer. Get one of these (I recommend the belkin wemo because you can turn the machine on when you're not even home!) and you'll never look back.

              A little disappointed to hear this as you just suggested the bz10 to me 2 weeks ago.

              I've been pulling shots at 12 bar since I got the bz10. But after a little reading I thought they were factory set at 11-12 bar. Thought it was unusual but didn't over think it. Now I'm worried I could be damaging the pump? If I change the opv to 9 bar will I be breaking the warranty?

                Can't answer your warranty question, but I'm sure the pump is fine. Why are you worried about the pump?

                  I'm hovering at 11 for most of my shots, only hits 12 for Backflushing.

                  I can probably say without hesitation, the "priming" of the BZ10 is loud-ish. granted doesn't wake my wife up at 6.30 when i flick the switch on, and we are a quiet household.

                  Grinding is louder ... (again... not a peep)

                      I thought the added pressure would put the pump under extra strain, like using a blind basket continuously? Could be wrong. Definitely no expert. Would be happy to hear I'm way off 😊

                      Thanks Paul, just a bit stressed about making a bad decision

                        The only thing that'll put undue strain on the pump is running it for too long. I'm assuming it's an EX5 so it's a 15bar pump with a max 1min cycle. So as long as you don't run it constantly for periods of time longer than one minute it'll be fine.

                          Any update yet? No word from the distributor?

                            In the days that we sold Bezzera, their techs had a habit of using loktite to glue OPVs to 12Bar.

                            It was an ongoing frustration with their gear which left us set to 9Bar after our bench test whether they liked it or not and not without frequent blood and profanity. In those times, many of the adjusty bits were near on inaccessible on some of their designs.

                            For mine, to say that 12Bar is normal = a cop out: i.e. we can't be bothered setting them. Does it mean that they will produce bad coffee? Hell no- but 12Bar can be a challenging drive.

                            Good machines generally built like tanks, but I don't miss the frustrations, nor the hot runners.

                              And not just on the OPV either...

                              Pretty well everything that had a thread was loaded with Loctite. Makes for an interesting exercise when trying to remove fittings from a copper boiler...

                                Hi all,

                                We are a long time seller and service agent for Bezzera
                                Like all machines they have developed over the years and what was sold three years ago is not the same machine that is sold today

                                I would doubt that the distributor in Australia considers 12 bar normal for extraction pressure. With vibration pumps they have only one speed and pressure, the control of the extraction pressure is down stream of the pump through the OPV.

                                Bench testing by most importers these days is a given, particularly with long and sometimes bumpy transits from Italy.

                                Unfortunately now days with "drop shipping" so prevalent the second level of testing by the retailer doesn't happen, and yes sometimes a machine not up to spec slips through.

                                Anyone in Melbourne can always contact us directly for Bezzera advice or repairs.

                                In fact I'm still waiting for Peteszad to contact me for his complimentary assessment of his BZ10 issues??

                                Cheers
