I have a livia semi-auto. last night i heard a loud explosion and saw water and steam going everywhere. the pump then began running trying to refill the boiler. i turned the machine off and unplugged it. the pressure did not immediately drop like it should. i turned on the steam and hot water dispenser and that helped to relieve the rest of the pressure.
has anyone had this happen with their machine? what is the cause and how do i go about fixing it?
Well, it sounds like you tripped the over pressure valve. This should only happen if your element just didn't turn off, and built up too much pressure. Why it did is the real question.

The reason for the bad pressurestat was probably due to limescale buildup but not totally sure. I haven't removed the old pressurestat to check. I have relatively hard water and learned that i need to replace the filter in my Brita pitcher every 3 weeks- max. instead of the recommended 6 weeks by the Brita manufacturer.
After talking with Jim @ 1st-Line, where i bought the machine, he informed me that it was a faulty pressurestat and the water/steam was being released from the safety valve on top of the boiler. He has placed a new pressurestat w/installation instructions in the mail to me. On another note, it was a very prompt and pleasurable experience. highly recommend 1st-line and Jim.
I had this happen to my Livia three times. The first two pressurestats lasted about four months each time before failing. I replaced the pressurestats with new ones from Pasquini. The third one only lasted about a month before it failed. Pasquini suggested that I return it for a re-wire job which would take care future pressurestat problems. I had this done about three months ago and so far the machine seems to be holding up. I don't know if you can expect the same type of problem re-occurance as I did, but you might want to talk to Pasquini (or 1st Line) about this possibility so you can have it fixed under warranty (assuming it's still under warranty now) if it happens again.

The "rewire job" was probably putting in a solid state relay between the pstat and the boiler element. It turns out the stock matter pstat can't take the current that the boiler element uses. The only pstat that doesn't need a relay is the sirai.

Is it easy to install a Sirai pstat to Livia? Do I need to adjust the boiling pressure after the modification? I am also interested in upgrading to Ulka EAX5 52 Watt Vibratory Pump. This pump should have generated less loud noise than the stock one as ChrisCoffee stated. Any one of you have done this before? Any suggestion? Thanks, - Joel
Saw your posting here and need your help as I have the exact same problem. Trying to email but djbrown@joimail.com is not valid address.
Just got a pretty old Pasquini (one without the pressure gauge in front) last month. It was fine last week but now after power on (7 min), there is a loud noise and steam start coming out of the valve on top of the boiler. This one is closest to the reservoir (pictures attached). Looks like there are 2 valves on top. They look slightly different. The one that has steam coming out is round and has 2 small openings on the side where the steam is coming from plus a small needle on the top. The other one right across from it, has only a small needle on the top and is not round but a hexagon shape.
If I leave the machine on, after another 2-3 min then the loud noise will come and steam coming out again. The loud noise is a little bit scary. Based on your postings, need to replace the pressurestat. Please let me know how to locate/buy/replace it. Also do I need to rewire anything ?
Sorry to revive this VERY old thread, but it's the only thread I could find that had my exact problem: the pstat on my Livia 90 failed about 4 months ago, and now this morning the brand new replacement seems to have failed as well.
This seems to have been brewman's experience, but I'm trying to be clear on the solution. It seems a need a new power relay.
