When I bought my machine, it wasn't working and was sold as "unknown, non-working condition". This model of espresso machine is super popular, and you can find a lot of info about how it works and how to repair every sin…
It has been a long time, but my espresso project is going forward, still in an always-alpha state. Stuff is hanging on the wires behind the machine, but it makes coffee, so I'm spending my time on other projects.
As you may have heard, an IT engineer is powered by coffee. While not always true, it definitely is in my case. I love coffee, and I'm a big fan of Italian coffee style: mainly espresso.
