Vesuvius Pressure Profiling Machine - General Discussion

DavecUK That makes sense. The pump struggles to pass the 2 bars during the preinfussion probably because the autofill valve is not 100% closed, this would explain why this happens only when the service boiler is under pressure. But I already changed this electrovalve so don’t know what to do next…

Thanks again,

This one (photo not from my machine):

I changed the whole brass piece, everything but the pressure sensor. Problem was there before changing all these spares.

No, steam is always normal, not super strong. The steam boiler seems to work all right.

It happens when the steam boiler is hot, no matter if it’s on or off.

Little mod for my Vesuvius . Ordered mirrored Perspex cut to size to serve as a shot mirror.
I think it blends reasonably well with the machine.

prezes Hello, do you have the link where to buy the mirror?

Kape17 sure, ordered from the shop below. The link will take you to the size in the photo (32cm long x 3cm high). I also ordered 4cm but couldn’t make it fit at right angle.

prezes It looks really good. How did you manage to fix it there? I assume it is removable so you can clean the tray every now and then?

John_Yossarian I was planning on attaching some foam to support on both sides so it’s stable but flexible. Funnily enough this size just sits perfectly on its own at right angle and doesn’t vibrate or move at all so can be easy removed as and when required

Cuprajake thanks. I was convinced it never done this before so thought I’ll check !

Yeah mine does it too

I think it’s the vacuum breaker as well, but as you say it’s doing it at lower temperatures, it might be sticking a little, until it cools down more. You can try steam cleaning it using the wooden spoon trick, or replacing the O ring….but it does depend on what type of vacuum breaker you have?

Photo please..

I lost the track about all these advanced setting in the machine… is the best way to go for settings according to manual or do you guys suggest to change some setting to get even better performance of the machine?

I mean for instance pump speed and so on.

DavecUK took me a while to get around to it !

prezes Lol, the only thing I can’t see is the vacuum braker as it’s on the bottom where the tubes come out of the t fitting, the safety valve is on top. From the base though my guess is it’s the black polymer one with a memory metal positive open and close. La Marzocco started using them about 3 or 3 years after ACS did.

It’s unusual, because they usually have a long service life….and they are a little expensive. About 7 to 10 times the cost of a normal if you buy one from LM, who seem to claim it as their own idea…which it never was.

It can be serviced and often a clean or new O rings (silicone or FKM can fix it.

DavecUK I wasn’t sure where it is to be fair! It seems to be matching your description perfectly.

prezes At almost £60 a pop, I would clean it 😃. In the past I was cleaning the vacuum breakers of all my machines regularly and they performed as expected.
