Hi all, I have just finished a strip down and rebuild of a broken Bezzera Ellisse, she was in a bit of a mess inside, but nothing too serious, she has now had a total de-scale and a service so everything is almost like new! It was a tense moment when I fired her up for the first time, but she sprang to life and everything works well.
Like most machine she now requires some fine tuning as things are not perfect, I am getting some lovely shots, but have noticed that the anti-vac valve on the boliler is hissing, I am trying to establish if she is running at too high a pressure, I kept my old machine running at just over 1 bar pressure, the Bezzera is running at around 1.3bar, I have not changed this, so this is how she was set up previously. If I tap the top of the valve the hissing stops for a period of time, but then starts again. The element is cutting in and out fine, so no issues there, but I guess if the valve is letting off to early this will cause the pressure to drop and the element will kick in again, so running costs will be up.
any thoughts?
