  • Bezzera Galatea Domus no water to group.

    Hi

    I managed to pick up an unused Bezzera Galatea Domus (unwanted prize) . All looked great, pump filled the boiler, steam and water are there, but I can't get any water out of the group. It's pumping and the pressure gauge is steady at 12 bar even after I abort. Is there something that needs to be removed from factory? The instructions didn't mention anything.

    Thanks for any advice.

    Hi soccersuite,

    Wish I could help you more, but I can't say I have much experience with the Galatea. Yelta is a big fan of his (see his other thread here); so hopefully he pipes up about any nuances in setup.

    That aside, maybe you could provide us some more info? Does it steam/hot water as expected?? How do you know the boiler is filled??

      Could be any of or a combination of OPV, pump, fill solenoid and other items.

      This is probably a job for a tech...

        Thanks for replying.

        It seems to steam and produce water as expected, however it does seem as though the steam runs out of pressure fairly quickly, and the hot water doesn't seem all that steamy (if that's a sensible statement), I'll observe more closely tonight.

        When I first turned it on, it pumped a whole lot of water into the boiler and was able to produce steam and supply water.

        I'm guessing that this was a demo model supplied as a prize, it's mickey mouse clean but didn't come packaged in a box. So I suspect it may have been sitting for sometime.

        I wouldn't mind doing some preliminary troubleshooting, the OPV seems to be doing something. When engaging the lever, the brew pressure gauge is holding about 12bar and the OPV is purging back into the reservoir.

        Should there be some audible clicking from the solenoid in the group?

          I say probably too, if I can't pick up on any clues that's what I'll do

            Morning SS, I agree with Chris (Talk Coffee) it's a problem for a technician.

            I've owned a Galatea for 4 years, have never experienced anything similar to what you describe.

            Is it pumping water through the group head without the portafilter in place?

            Hopefully it's not a major problem.

              Don't know this machine in particular but did a quick google search and it says that it's an E61 heat-exchanger machine. For the pump gauge to still read pressure after abort sounds like there's a clog or something in the solenoid 3-way valve or even before that. Usually when you abort, any back pressure/excess gets dumped through the return and you hear a swooshing sound.

              Also, 12 bars of pressure seems really high. My E61 grouphead machine comes with a Parker-Hannifin valve that's rated 0-10bars. You might want to check your pressure regulator at/near the pump as well. You can check the pressure by looking at the gauge during the boiler fill. It should read just about the same pressure as your extraction, maybe a few bars under (depending on the routing of pipes and the restriction).

              Hope this helps!

                Ben the gauge on the Galatea indicates boiler, not grouphead pressure, I suspect the pressure indicated is 1.2 bar not 12

                  Thanks for the replies. Nice to get some advice.

                  Not sure how relevant but when it was filling the boiler after I was playing with the steam, I'm sure the gauge was reading far less tham the 12 bar when trying to get water through the group. I'll have to confirm tonight.

                  There's not a drop of water on the screen, portafilter or not, it's completely dry.

                    I've got two gauges, one for brew pressure and one for boiler pressure.

                      Have a close look at the gauge this evening, pretty sure the figure your looking at is 1.2 not 12 bar.

                      Bezzera Australia are up your way, Coopers Plains, just south of Brisbane commercial link removed per site posting policy, very helpful people, why not give them a call.

                        Are you certain yours is a Bezzera Domus Galatea? seems the latest model only has the boiler pressure gauge commercial link removed per site posting policy Retro Styling Bezzera Domus Galatea Single Group Coffee Machine[/url] unless someone has added the extra gauge.

                          It looks like this one:

                            Interesting, that is certainly a Galatea with an extra gauge, never seen one before.
                            I notice under their specs they only mention an (Eye level boiler pressure gauge)
                            As a matter of interest you make no mention of a grinder, do you have one?

                              I certainly do, however as I've not even close to getting this guy working, I deemed it irrelevant to this thread. I've got a Mazzer Mini.
