  • Breville 870 never gains pressure, chronic under extractions, any ideas?

    This is my 3rd espresso machine. I tried all the tips found in here from grind size/amount, tamped with the force of 1000 elephants, overflowing with fine grinds and the machine still gets zero pressure, the needle just barely moves.

    I watched the Breville official video and his needle moves with almost no tamping pressure so I can't figure out what the issue is.

    Breville has ignored all my support requests so I'm hoping for some help in here.

    First thing to try I think is to put the rubber disc in the portafiller like for the cleaning cycle and hit the 2 cup button. On my machine the pressure gauge moves to the middle of the grey area, this will confirm if the gauge is working or not.
    And welcome to the forum.

      lordmandrake,

      Welcome to CoffeeSnobs.

      While you have low pressure, are you getting any flow of coffee?

      What is the pressure like if you block the flow with the plastic disc?

      What coffee are you using?

        So I just tried this and the needle didn't move at all, not even a tiny bump. The machine is brand new, literally just out of the box yesterday.

          The pressure is zero but coffee does come out. It's shitty espresso though, watery and weak. I put the plastic disc in and still no pressure. Using arabica beans.

            You've got a faulty machine. Just pack it up and get an exchange, tell them that the pressure gauge is not working.

              I bought it on the internet though so I guess I'm just screwed. My old one finally broke after years of faithful service. Saved up for the Breville. Tapped now. Forced to be another Starbucks zombie until bonus time.

              So your pressure gauge will go into the middle range with just the plastic disc in there? Did it do that from the beginning, or did it take a few weeks before it fully pressurized?

                  :O

                  Seriously?

                  If coffee comes out, there is pressure. If you can produce coffee, and the machine is otherwise functioning fine, the gauge is superfluous anyway. Many machines don't even have them.

                    It may be superfluous to someone that knows what they're doing, however this guy is a beginner and the gauge is a great help on the learning curve.
                    Anyway the machine is not functioning properly and I wouldn't be satisfied with it.

                    Would you drive your car or teach someone to drive with no speedometer?

                      The tractor and paddock-basher i learned to drive in had no speedometers.
                      you drove to the conditions, feedback and the limits of the car/ road/ grip.

                        How fresh are your beans? When were they roasted? Are you grinding on demand?

                          Yes, my machine the pressure was always there if the disc as in, no build up.
                          Although the machine will work without the gauge, you're going to waste a lot of coffee getting it right as you can only go by time, look, and taste and that is not satisfactory imo.
                          If you paid by credit card you must be covered by some sort of insurance, so get onto them and explain that you have faulty goods. The outfit you bought it from may surprise you and exchange it and you just pay return postage.
                          Good luck anyway.

                            So if you bought a brand new car and the speedometer wasn't working, what would you do?

                              Well I would need to drive it as fast as it can go to see if any part of the speedo's range wasn't working, if it was confined to the very low end of the scale.
