  • What is it - what does it do?





    Hi Guys, Just wondering about the purpose of this small bolt on the front of the Group. I dismantled the Group recently to clear a suspected blockage and took the bolt out as well but could not see what purpose it serves.
    Thanks in anticipation...

      This is where I fitted a digital temp probe on my VBM very useful for cooling flushes,

        Thanks 2mcm, the pictures are very helpful. Im guessing that the small round bolt seals an inspection or maintenance channel in the Group Head.
        Chris, I like the idea of having a temp probe fitted there as I suppose it takes all the guesswork out of knowing whether your machine is maintaining a correct water temp at pour.
        Any pictures?

          Quite right!  If Im not mistaken, that bolt seals a shaft made during construction.  As theres no way to drill a 90 degree bend, they drill two perpendicular shafts and then plug the end of one of them - thats the Hex nut you see.  Pic with arrow pointing to the bend attached.

          The temp probe down the throat can be fitted with Eric Ss adaptor. Details are here: http://users.rcn.com/erics/ and very detailed comment is on the home-barista.com forums

          Happy reading

              Thanks very much Epic & RZ. I never cease to be impressed by the helpful cameradrie of the CS fraternity.
              I am having a problem with my machine at the moment and am looking at all the possible variables that may be implicated.
              I noticed when I removed the little round bolt that there was no washer and it appeared to be set in place with a locktite type of material which I suspect may have travelled down the shaft and be causing some problems at the bottom (escape) valve.
              A bit more investigation to be done when I get the right sized spanner tomorrow. I will post a thread on the matter.
              Cheers.

                  The instructions for installing Erics thermometer mention a washer.
