      Something I also noticed from your photo in the opening post, is that there appears to be lot of detritus in the water tank.
      If this is the case, maybe your water filter options are not working well, and some of this 'grit' is finding its way into parts of the hydraulic circuit that it shouldn't.

      Please disregard if this is not the case...

        Ok so I finally got a chance to open up the machine, but am not sure what I am looking for? I placed the water tank up the top to get a clear shot.

            Yours has a vibe pump, not rotary. Hard to see without being able to follow the piping but the valve near the tank looks to be the pressure adjuster.

            Do you see any change in pressure using a blind when this is adjusted? Is there any water bypassing out of the plastic hose?

            Cheers

              I've turned that as much as possible and tightened one of the bolts and managed to get it back up to 7 bars, that's all. Checked all the plastic hoses and there doesn't seem to be any leakages.

              Thanks.

                  If nothing is working, I'd book in a service to get it sorted.

                    If you do get it serviced, would love to know the outcome. I have one of these machines, and as much as I hope it won't break down, would be good to know if there are any things to look out for.
                    Have you considered that it might be scale?

                      Still using it at 7 bars. Noob question but is descaling same as back flush?

                        No! Back flush is removing the espresso coffee deposits. Descale is removing the boiling water deposits in the boiler. Very different areas and chemicals!

                          Are you getting water flowing out of the hose if using the blind?

                          This would indicate you are bleeding pressure and the OPV might be the issue.

                          If no flow then it might be your pump not producing enough pressure.

                          Cheers

                            FWIW I had same problem.

                            Turned out pump was in slow decline.

                            Replaced pump and now back at 9-10 pressure.
