  • Re: Breville BES900 Dual Boiler - Owners thread

    I normally hold the 2 cup button to water backflush for 6 seconds only so it does not register as one of the 200 shots required before the machine shots before the machine prompts "clean me"

    I assume the 7 second shot time that registers is correct as previously stated?

    Not that I worry about the clean me cycle anyway as I chemical backflush after 1kg and tie that in with cleaning my grinder.

      Thanks for your reply. I will try the method you mentioned to see if the piping from soleniod valve to the drip tray will look cleaner. I checked the section of the pipe from 3-way valve to drip tray is a little brown, so there is some oil adhered inside the pipe.

      Currently my unit has pulled over 360 shots in 2 months. So what will happen to the unit if it is over 6000 shots? Any way to reset it if I cannot ship the unit back to Australia for service?
      OK, the tubing from the 3 way to the drain only ever has "dirty" water flowing through it, apart what is expelled during a clear water back flush or clean, so it will get "stained" by coffee oils. This is normal.

      Nick, stop worrying about your machine. These machines have been tested to make 14600+ shots without failure. Should you need to have it de-scaled at some point, then you could send it to Sydney for a service OR you could use the instructions & online video that will be out there for the DIY by the time this happens.........

      As for the pressure, as Ive said previously, this is a very elastic variable in the espresso making process, 8-10b will yield results with little to no difference to taste in the cup.

      Cheers, Phil

        OK, heres my standard procedure for cleaning:

        After each session: "clear water back-flush"

        Insert blind filter into PF.
        Insert into group head
        Press & hold the 2 cup button for 10 secs, repeat 4-5 times
        run PF under hot water & wipe out.

        Every Kg or so

        Clear Water Back-flush as above, then
        1/2 scoop caffeto or similar into blind filter
        insert into group head
        press & hold 2 cup button for 60secs
        allow to "soak" for 60secs
        press & hold 2 cup button for 10 secs, repeat 4-5 times
        repeat clear water back-flush
        soak PF (head only, not the handle) in solution of Caffeto & hot water for 10mins, rinse after

        Cheers, Phil

        thanks for this, phil.

        would you say that conscientious application of these procedures would make the "clean me" procedure superfluous?

        not that the machine would let you off of doing the "clean me" cycle or anything.  i was just curious if the steps you listed are standard for keeping most all pro-sumer-grade espresso machines clean.

        the machine ive had for the 12 years prior to the BDB did not have a 3-way valve or an OPV, and only one boiler.

          Hi Pete, yes it would make the clean me message redundant. A good reminder for those not as religious in their cleaning habits........

            Well its been a while since I last posted. Everything is going very well.
            Im finding that the coffee always comes out different with every different bag of beans I buy. My beans are always fresh from the same company.
            I always have to change dose and grind with every different bag.
            Seriously my family are sick of me always asking "Hows that one taste"
            Although my daughter did say she cannot buy espressos any more !
            I think when I grow up I need to get a life !

              I clean my machine with fresh water after each session as recommended by Phil and do a chemical backflush now and then. The "Clean Me" sign has never come on.

                The "Clean Me" message will be shown up every 200 shots.  An extraction over 7 secs is counted in as one shot.

                Thanks

                  Hi Phil,

                  Thank you for your patience to answer my questions. I am very soory to post incorrect message with regard to descaling the machine here. Those message posted by me should be deleted from this forum.

                  Also, I found a very unique design in BDB that has never been discussed but the unique design really changes several common characteristics seen on traditional HX and DB machines.

                  The unique design I believe is the hot water tap connected to the brew boiler because

                  1. The steam boiler now only acts as the heat source for the heat exchanger to the brew boiler and the only surce of hot steam. If we observe normal HX or DB machines, their steam boilers intake more clean water and drain more waste water for the E-61 group head, so the limescale is much easier to develop than their brew boilers. On the contrary, I barely notice the steam boiler vibe pump to prime clean water from the reservior because the amount of steam water needed to heat the milk is relatively less than normal steam boilers. Hence, to develop limescale on the wall of the BDB steam boiler will take much longer time than any other HX and DB machines. If my postulation is correct, the BDBs brew boiler is more easier to develop limescale than its steam boiler.

                  2. The unique hot water piping avoids temperature fluctuation of the steam boiler and results in constant tempeture hot water to heat up the heat exchanger because there is not much hot water drained out from the steam boiler (except for the steam but its amount is very small).

                  3. As the size of the brew boiler is much smaller to heat up more quickly and the PID-controlled heaters built inside of the brew boiler and the group head, the hot water primed from the heat exchanger to the brew boiler can be easily heated up to maintain at the regulated brewing temperature. The most interesting thing is the BDB consumes less wattage to achieve steaming and brewing function as the same time so it can be powered by 110V with less than 15A. The BDB design is indeed more energy saving than other traditional HX and DB machines but also has faster warm up time to the regulated temperature for services.

                  Future design enhancements to BDB, as Phil said, could be easier user self-maintanance which is fairly easy to achieve by adding an outlet from the bottom of the steam boiler, using brass outlet ULKA vibe pumps with brass OPVs.

                  Regards,

                  Nick

                    Hi All,

                    In my usual cleaning procedure, I decided to use the built-in cleaning program (never used before) with a blind basket and half a scoop of Cafetto. I fear this may have caused some problems.

                    I thought that the cleaning program would just run the pump repetitively and release the solenoid each time. I was wrong - the solenoid isnt activated until the very end (after ~3 minutes or so). As the water sits in there, the pressure gradually goes down to about 5 bar - although I could not see any water being released into the drip tray.

                    After the cleaning program was finished, I was alarmed by how white the water looked. After heaps of flushing (a whole tank), I managed to get the water looking normal (clear) again. It appears that the Cafetto went back into the brew boiler - I didnt think this was possible.

                    So, while the water appears fine now, is there anything I should be concerned about that might affect the longevity of my brew boiler now that it has come in contact with the Cafetto? Fortunately, the water tank isnt affected, so I would assume the steam boiler is fine.

                    Thanks!

                      Yes, no problem in your cleaning process. The BDB "clean me" process seems only clean the path between the brew boiler vibe pump and the group head and the 3-way solenoid valve is not activated during the cleaning process.

                      In the cleaning process, the detergent is also left inside of the brew boiler. Half spoon of detergent may be too many for the 320 secs cleaning process. The amount of detergent depends on the type of detergent and the design of the brewing system. In case of using too much detergent, just simply flush the group head with sufficient clean water.

                      If you descales your unit, dont steaming in the whole process as the steam boiler itself is a closed chamber system and steam wand on the top of the steam boiler cannot drain the boiler. If the steaming triggers the auto-refill in this case, the descaler solution will be primed into the steam boiler so you will not be able to flush the descaler solution out of the steam boiler.

                      Regards,

                      Nick

                        Correct, a blind filter is a filter basket with no holes in it.
                        Those interested in a "free" blind-filter for your BES900, for performing Phils cleaning regime, might like to look at this video.

                        It requires nothing more than your standard basket, the silicone cleaning disc, paper towel and aluminium foil.

                          is there an easy way to check the pressure is set to 9 bars
                          Put the DUAL WALL single basket in the PF, then press & hold the 2 cup button. You should see approx 7bar on the gauge. If it is 7bar+ then the pump & OPV are fine and you need to do as muscles suggests, dose higher &/or grind finer. I would suggest starting with grinding finer.

                          Cheers, Phil

                          Hi Phil,

                          Mines goes to 8. Ok or not?

                              So I just got a Breville BES900 and a Cunill Cafe T Ranquilo grinder.

                              Ive serinder to deliver 10g of coffee and have set it at its finest setting which seems to be about the same as prepackaged espresso coffee.

                              I dont seem to be able to get the pressure above 3 bar using the single wall filter basket. Ive checked using a double wall basket with no coffee and the pressure gets up to almost 7 in manual mode.

                              Needing sone guidance - Previously had a Saeco fully automatic.
