Thanks for the pics and explanations above. I had a problem with the boiler level on my Semiautomatica increasing spontaneously at random times. I disassembled the valve per instructions above and found a big glob of mineral deposits on the valve seat. Scraped it off, reassembled, and the problem was fixed. This forum has saved me and my machine many times!
