Thread: Steam coming from grouphead / Silvia

My Saeco Via Venezia always does this. I just figured it was because it is a thermostat driven machine so the temperature can spike up to boiling temperature sometimes, so this creates steam and it has to go somewhere, whether it forces water back down the inlet piping and the steam occupies a tiny space in the boiler which then purges initially when the group is opened.
Maybe it's not meant to do this and something's wrong. By this logic, perhaps your thermostat isn't switching off soon enough and is causing some steam to be created in the boiler when it shouldn't be? I'm not sure, still quite new to small boiler machines.

I have the same thing on my v3, I'm guessing the boiler just gets too hot and starts producing steam ? I also get steam coming out from around the group head when the portafilter is not locked in

Thanks for the replies. I did wonder if it was just a temperature thing. I usually try to purge out as much of the steam as I can without dropping the temp too low...

I have an auber PID arriving this week, so I hope that resolves the issue..?

There would be a bit of pressure in the boiler, so when its released outside of the grouphead to a lower pressure (assuming the temp stays quite constant) then the volume will increase a.k.a to steam.

My silvia does the same thing and I haven't seen it to be a problem. I believe there was a bit less steam after install the auber pid simply because it doesnt get as hot as the thermostat allows it to initially.

I had the same issue with my Pre-PID Silvia too. My temp surfing involves a slight purge once the boiler light goes off on the top range before I lock and pull my shot.

With the PID installed.... No more temp surfing and purging needed

Yeah, I was hoping the PID would resolve this. Really looking forward to the PID being fitted

Did u get the one with the steam control too? I find the steaming power seems to last longer and more powerful than before installing it.

After using my isomac tea for awhile, I had the misconception that the Silvia's steam was low, so when I demo it to the new owner, It blew a fair bit of milk on to me on the first blast

Well, the new owner was very happy to see that it was strong. And darn easy to make nice silky steamed milk.

Yeah, I ordered the steam control version. I decided the pre infusion version wasn't worth the extra pennies cause it's not a real pre infusion anyway...
