Glad to hear its working well for you!
I do have a Conti... A 2 group Conti club.
I was having flashing lights several weeks ago and it was suggested the machine has Calcium deposits that are restricting or blocking the water flow.
I use the machine in a small coffee cafe in my church and got the machine second hand after it sat for over 5 yrs. I've been learning and fixing things as I go.
I haven't had the time to or opportunity to do any kind of large scale breakdown & clean out but did let the water flow for 5 or 10 min to see if that would flush things through a bit and haven't had the flashing lights issue since.
However... Now I'm having an issue all of a sudden where the [what I believe is] pressure relief valve is continually engaged, hissing & releasing [small amounts of] steam.
I can't find enough on this machine to determine the possible causes or solutions.

There does seem to be a disappointing scarcity of info or support for these machines, it's true. In fact I just attended the SCAA Annual Event in Portland, OR, and Conti didn't even have representation in the exhibition hall, where there were over 700 coffee-related businesses on display. All the major machine-makers were there. No Conti.
At any rate, I believe that it is possible for pressure valves to accumulate scale as well, from condensation of the water that forms the steam that passes through it. You might want to try removing the valve, soaking it in descaling solution, rinsing/reinstalling and seeing how that goes. Alternatively, we had a problem with a pressure valve on our Rancilio Epoca in the cafe where I work, where it was hissing and letting off a tiny bit of steam at all times. In that case it turned out that the little plug inside the valve had simply wiggled slightly out of place and got fixed in that position. Via phone our espresso tech just told me to take a screwdriver or whatever and tap it or nudge it a little, and sure enough it repositioned securely; no more hiss.
Out of curiosity -- the Sirai pressurestat inside your 2-group machine... Is it by any chance mounted sideways? I had a heck of a time recently trying to turn down the pressure of my boiler because it was running way too hot, and I discovered my pressurestat was mounted sideways and I couldn't get the lid off to turn the adjustment screw. With help I eventually came to realize that there was a hole drilled in the lid, through which I was able to just barely get a screwdriver in with enough leverage to turn the screw. Kind of an annoying little quirk, I must say.

Please help me figure out why my conticlub one group machine keeps demanding water when it is full thus causing the boiler safety valve to overflow? I tried turning it on and leaving the steam wand open a bit to relieve the pressure but after about 15 minutes of being powered on it clicks and demands water over andover again. I have had this machine for about 3 years (got it brand new) and it has never been serviced (nobody here in Hawaii). Is there anything I can do? I have the back flush detergent and the dummy portafilter; should I do that? Can I do that without the machine being fully heated? Forgive my ignorance and neglect on my machine; my x husband ran this cart and apparently did no maintenace to it. Please help me! Thanks, Mhamm

Michelle Please only ask your question in one forum, multiple posts on the same subject is against the rules of the forum AND it makes it hard to find the answer when people DO answer you, I did on one of the 3 times you asked this question.
