Just finished my first test run of my M27 Start. All seems to work O.K. except for a very small but constant leak/hiss from the anti suction valve. I will remove and inspect for the cause, but what does this valve actually do? P.S. love the "dry" steam this machine makes!

Re: Anti Suction Valve Leak
Thanks Mal, a wealth of information there alright. It seems the small "leak" I have noticed is relatively normal on this type of machine. I had expected a bit of a splutter at start up, but not an almost continuous tiny outflow. Any comments from owners of (older) La Cimbali machines regarding the output from this valve would be appreciated.

Re: Anti Suction Valve Leak
ento,
It needs a kit put in it....
The antivac valve on an LC should splutter at start up - as you suggest.
It should then seal totally (nothing coming out at all)... either the seat is damaged or corroded... or if you are lucky.... just the O ring will need replacement.

Re: Anti Suction Valve Leak
JavaB exactly right as usual. O-ring was as hard as nails and broke apart when removed. Seat has very minimal surface deterioration, I am certain it will easily seal when under boiler pressure. Now I need to complete the permanent plumbing hook up so testing/tasting can resume!

What do you mean by this.... :-?
Usually = implies that it may not always be so.
When have we ever known JavaB to be wrong

Re: Anti Suction Valve Leak
Semi permanent plumbing done, and machine up & running. May be a small leak from the hot water valve as I have noticed a drip which seems to come and go irrespective of valve usage. Functionally though the machine is brilliant, makes a great long black virtually every time on both the single and double baskets, and the misses are always obvious in cause - (new beans, small grind change needed is usually the problem). Now, I just need to tame the steam/milk interface........
