    Re: La Scala coffee machine

    Hi Lovey,

    After a private conversation with 2MCM I have modified my post to better reflect the current situation with the Giotto. But the reason I made the comment was that, at the time I bought my machine I was seriously considering the Giotto. My local coffee roaster sold the Giotto exclusively at the time but told me there had been an issue with a batch of boiler pipes (made in Holland, I think he said) having too small flarings on one end and that the machines from that batch had all failed resulting in the contents of the boiler ending up on the bench. Long story short, he had lost confidence in ECM and ceased to stock them. I had just discovered the La Scala machine and he got one in for me, which I bought. He told me that the Giotto was going to then be made in NZ under the Rocket brand name.

    As I had bought my machine and am just a home user, my curiosity with E61 comparisons ceased at that point and I had no reason to continue researching these matters.

    I posted what I last knew to be the case and I am endebted to 2MCM for enlightening me to the fact that they went back to making the machines (of original quality) in Milan.

    This all serves to make the point that saw me join this discussion forum in the first place. All E61 machines are likely to be of similar quality and its likely that our personal prejudices and lack of up-to-date knowledge seem to be what causes all the fuss. Just buy the machine that has the features that work for you and, chances are, it will be great. From my experience the La Scala Butterfly is as well made as any other machine. There are some close-up internal images on the internet that support that.

    As I am new here, I have not yet posted my review of this excellent machine, but I intend doing so.

      Alas, if only this were true!

        Hi All
        Looking for some advice on a rebuild of a La Scala Butterfly. After a full tear down, new element, new solenoid, pstat and descale, I've got the machine functioning well. However I think there is still an issue with the pump or OPV. When taking water from the boiler through the hot water tap, the pump kicks on (good), but seems to take a long time to refill the boiler (much much longer than my Rocket Evo). When the pump is refilling the boiler there is a pretty steady flow of water through the return tube back into the water reservoir.

        Is it possible that there is something stuck in the OPV which is diverting part of the flow back to the tank? I did descale the OPV, but didn't take it apart completely.

        Any help is appreciated.
        Thanks

          An alternative possibility is that you've got something wrong in the rebuild and have restricted flow in the boiler refill pipework to the point that the OPV operates.

          You could distinguish between the two by disconnecting the pipework immediately after the OPV. If the diversion continues, check the OPV. If it doesn't, check the boiler refill.

            Thanks. Could be a possibility for sure. I had to replace the boiler inlet elbow as it was the thing that caused a bunch of issues with a hairline crack & leak.

            Thinking about it now, when using the group, the pressure seems to be fine through there (although I have no way of testing). The shots that I've made are great. So does this mean that its likely not the OPV and more likely flow restricted into the boiler, which is kicking the OPV into action?

              Update on this one. I checked last night whether water flows back into the water tank when engaging the group. It does. At about the same flow as when the boiler is refilling.
              Is there a way to test the pressure at the group without specific equipment? When I compared the flow rate out of the empty group with my Rocket Evo, I got about 2 cups of water in 30 seconds compared to 1 cups with the Butterfly in the same time? No idea whether anything can be deduced from this though?

              Given both the boiler refill and group seem to be restricted, is it fair to say I may have something in the OPV that's preventing it shut off / seal completely (ie. pressure set too low on the OPV)?
