    Re: ECM Veneziano A1 Help...

    Hey Bon, Im just wondering if you managed to change that setting.
    If you did, what was the result? I have the same machine, but I havent really tinkered with it because Ive been happy with it they way it was delivered. Id be interested to hear about this and any other adjustments youve made.

    Regards Bart.

      Hey Bart,

      I tried changing the pstat... I saw the pressure go up to just above 1, but it keeps dropping back down to 0.8. Not sure what the go is, steaming power/pressure is no different.

      I am going to have to keep fiddling with it, or get someone to help me.

      Whats your machine set at now?

        Gday Bon, mine sits on 0.8 and produces really thick microfoam. I upgraded from a San Marino CK Compact which was a good machine but I have to say the ECM leaves it for dead. Steaming milk on the A1 is a bit slower than the CK, but the results are much better.

          Hi Bart,

          there is a set of mods for the A1/S1/Giotto which provide 1.2bar boiler pressure whilst retaining correct group temp- i.e better thermostability- Say goodbye to flushes to cool- I flush only to rinse....I am getting some kits of bits and can do it....for a price ....The results are FANTASTIC!

          I have run mine in this configuration for 6 months and would never consider going back....

            And what kind of bits would those be 2mcm? Im asking for the sake of transparency...3rd wave

              Its not possible to jack the machine up to 1-1.2bar without these mods? Ive tried, but its still sitting on 0.8.

                Possible but not advisable as you will be waaay too hot at the group head....

                  what about pushing the probe in?

                    Bon,

                    Im not sure what you mean by probe.... boiler pressure and temperature are both determined by the pressurestat.... increase pressure = hotter boiler...

                    The brew pressure is determined by the flow of water through the group and through the heat exchanger.....which depend on boiler temperature -- and without changing flow restrictors and thermosyphon pipes etc the brew temperature will increase in line with the increase in boiler pressure / temperature.

                    Tuning a commercial or prosumer machine for good performance is a lot more than rotating a screw on the pressurestat.

                      I think he was referring to the Water level probe which will change the water to steam ratio in the boiler and change the heat X-fer to the water in the Hx i.e if your running at a higher pressure then you could lower the water level so less heat is transferred to the water in the Hx.

                        :-? Which would lead to a greater fill of the boiler and therefore less volume of steam if Im not mistaken??

                        I really wonder why you feel that you need to increase the perssure anyway. The A1/S1 had plenty of quality dry steam..If you are having problems texturing, you may need to adjust the nut on the group handle ;D

                          segrave is correct.

                          I have no problems texturing milk (just slow)... yet, when I go to another machine that is set for a commercial environment, Im overwhelmed by the amount and power of the steam so I wanted to jack my machine up to be more like one set for a commercial environment.

                          Plus, I also wanted a higher temperature in the group head... there is one particular blend I have been trying to pull for a while which keeps coming out astringent - Im told I need a higher temperature which is really the only thing left to try as I have been through a variety of baskets, dosed less, dosed more, etc. and I can get a decent shot out of just about everything else I put through the machine.

                            In which case, Id be looking very closely at the coffee...Have you cupped it and seen the same astringency....Sounds like a fault to me....Some roasters blend to a recipe and as coffee does change, its not always the way to go....

                              Whoa! this is getting way too complicated for a simple fireman, my enquiry about modifications was really only out of curiosity. I am actually very happy with the performance of the A1, if there were minor adjustments to tweak things up a bit, I might have a crack. But this is too deep for me. My motto, if it aint broke, dont fix it!

                                Bon, are you sure the commercial machine hasnt got more and bigger holes in the steam wand tip?
