    Every Machine is different and thus you have to try..  The ones in the training have often been set to be about the same.. Or the instructor will know their setting for the beans they are using.

    If 6 = 2:00 and reduced pour  and 15 = Watery and 10:00

    Then as per the SB manual it may need to be around 10 - 12 ...

    The settings are rather course and not exact...  Thus one or two clicks at most and then a couple of shots...

    Have you done the test yet to see where you sweet spot is ???  

    On my three is it 11:00, 12:00 and 2:00  All different and thus as we have said the gauge is a GUIDE.  Further more they all require slightly different dose levels and tamping due to age etc etc..

    Do not rush and then blame the equipment... As most of teh CS members will tell you... Many times it is PEBKAC.

    Keep trying and take it slowly..

    well just tried again.

    at 15 the needle is barely at 10ish and very runny.

    consecutively going finer on the grinder gives me consequitively higher pressure gauge and genuinely better coffee smell creme texture and all.

    So again after trial and error i seem to be back down again to about a 5 right now and with an 8 i get center line on the gauge a 5 gives me a 2oclock position.

    thing is though even at the coffee school did not see anybody using 10 or 12 etc and as the room heated up the grinds got finer down to a 2-3 lol.

    at 12 with all the tamping it still comes out waterish with not enough creme with the gauge at about 11ish


    I will try that thing with gauging my own machine tomorrow and report then but for now im stumped.

      lol couldnt wait till tomorrow lol

      ran it with the 2 cup dual filter with single hole at the bottom and that shows on my gauge that my sweet spot is apparently at roughly the center of that ideal zone. So not the 2oclock but rather between the Yellow and Orange zones putting it at roughly 11ish?.


      and im guessing that at 6 grind setting i was getting the brown 2oclock spot that at 10ish ill get that spot?

        NOW... With store beans from the local shop your not going to get the quality of crema or flavour...

        Fresh beans will make all the difference, and your grind will change..

        Old / Stale beans usually require a finer grind (my experience) with the EM0480 as they (beans) tend to loose their hardness and tear rather than grind..

        12 - 13 for good beans on my 0480 and about 10 as they get older. GJ and others about 10 - 8 and a different tamp pressure but still not the quality output.

        Use a duel floor basket at 10 - 12 -14 grind a firm tamp and watch the difference... Fake crema....

          Re: SUNBEAM em6910 flow issues?

          My advice is to ignore all the dials and scales and go by the results. I have recently done a fair bit of experimenting with my EM6910 and EM0480 to learn a bit more about how various parameters affect some aspects of extraction. In the end, it boils down to the following steps in that order:

          [edit]0) Only use the single floor (non-pressurised) double basket. The dual floor (pressurised) baskets make it too hard to make decent coffee. They hide the extraction characteristics and provide artificial back pressure / flow restriction.[/edit]
          1) Learn the correct tamp pressure. Use bathroom scales until you get a feel for what 15kg of pressure feels like.

          2) Get your dosing and distribution right. When you fill the basket, ensure that the untamped coffee is evenly distributed all the way to the edges without any air pockets. Once tamped with 15kg pressure, the coffee level should be such that about 1/2 of the silver part of the Sunbeam tamper is inside the basket and 1/2 is above the basket rim.

          3) Adjust the grind. This is the variable that needs to change on an almost daily basis. As your beans age and the humidity increases and decreases, you may need to tweak the grind coarser or finer. Every EM0480 is different - setting 6 on one will be same as setting 12 on another. Start somewhere in the middle and pull a shot. If its white and runny, make the grind finer. If it wont come out and/or only gives you a few black drops, make the grind coarser.

          What you want to see is the pump going quieter and the pressure gauge needle stopping (doesnt really matter where). Once the needle has stopped, itll sit in one position for a little while. The coffee should not come out straight away. There should be a small delay before the first few black drops emerge and quickly turn into a dark brown trickle with orange stripes. Slowly, the colour of the extraction should change from mainly brown with orange stripes to mainly orange with a bit of brown. Very soon after that, you will see the crema starts going pale and turn first to yellow and then starts drifting toward white. If you let it go any longer, the coffee will turn from opaque to semi-transparent liquid. At that point you are over-extracting. As the extraction proceeds, the pressure gauge needle will back off a little bit.

          Correct grind is the most important factor. As an example, I had to switch the setting from 13 to 19 when I switched between two different kind of beans. I then had to change the settings another two notches as the beans aged from 3 days old to 10 days old.

            Re: SUNBEAM em6910 flow issues?

            and just to add another variable into the mix, the quantity of beans you have in te hopper of the 480 "can" have an impact as to how fine you need to adjust the grind collar.

            The grinder likes to have the hopper about 1/2 full or thereabouts providing weight on the beans as they pass through the burrs and stopping the beans "popcorning".

            Before I really read through a lot of posts on this site, I used to get frustrated that the grinder seemed to need "constant adjustment" and that one setting wasnt all I needed (afterall, none of the coffee shops I used to buy coffee from seemed to adjust their grinder - well, I never saw them doing it). Now I just accept that there are so many variables in making a "good" coffee that its just normal.

              ok just to get some figures here should it take about 2mins on the 2oclock position? for about 30 seconds or so nothing even comes out and then when it does come out its a very thin trickle. Does that sound right for the brown spot 2oclock??? Because the schools machines took maybe 5 seconds and then an even pour came out total time maybe about 30seconds or so with nice thick creme etc etc


              What beans and from whom should I order? Should I get it from 5 senses? somewhere else?
              I like columbian on the cheap end and Hawian Kona on the expensive end.

                    Re: SUNBEAM em6910 flow issues?

                    I can vouch for cuppacoffee. We only buy from Dennis - and even though Im in Brisbane, it works out very reasonable (including freight) - and the beans are fantastic. Hell post them just after theyre roasted so they arrive fresh. Not only that, but his customer service is superb (I feel a commission cheque coming on!!). And jsut remember that a few dollars per kilo extra (if, indeed he is at all more expensive) s just a few cents per cup and it really makes all the difference on your tongue.

                      Re: SUNBEAM em6910 flow issues?

                      alright ill get some coffee from one of those sources and update again.


                      Who carries Hawaiin Kona or Jamican Blue mountain???? Cant find any except 1 site that had 1 kg for about $320!!!!!
                      I used to pay
                      ~$100 for 1kg blue mountain or kona
                      ~$32 for colombian etc most south america africa png etc




                      and im not sure if its my imagination but I think not sure that the flow on my machine was better and lots more creme was coming out before. like i said look at the times i am getting now

                        You were on the right track there.
                        Ignore the guage and get the coffee hjow you like it then see what the guage reads.
                        The most important thing is getting the grind and the pour right and it look like you were almost there.

                          thats what i thought but the following 2 points:


                          ok just to get some figures here should it take about 2mins on the 2oclock position? for about 30 seconds or so nothing even comes out and then when it does come out its a very thin trickle.

                          and that unless im mistaken the pour was better when i had gotten the machine has left me confused whether it can really be the beans? ( though I will get some fresh ones) because im certain i was getting good flow and the right pressures and the coffee would come out nice with plenty of creme in comparison to now.


                          what are your times and settings of choice?

                            sampam,

                            Did you get the DVD with the machine? If so, I recommend watching it. Copy his techniques.

                            After going full circle and having now gotten my routine down pat, I was suprised to watch the DVD and find my techniques closely matched the presenters.

                            Watch the DVD a dozen times if you need to. And remember, your dose and tamp should remain consistent. Only the grind should change. If you keep changing different things, including your bean type and going from single to double baskets, its kinda like trying to shoot an erratically flying bird with a rifle; its very difficult.

                              I aim for 50ml double in about 25 secs. Im lazy and use the double shot button, but manually cut it off.

                              On my machine, the gauge / needle hits around 2 oclock to hit this result. Beans are between 3 and 17 days post roast (get 1 kilo which lasts 2 weeks) and most of the coffee is kept in a click clack container (except as I said, the 480 likes beans in the hopper to get the most consistent grind)

                                small thread hijack, but does anyone know if the DVD is available as a d/load from anywhere (sunbeam?). DVD wasnt included with my machine. Whilst I have had it a year, and think I do pretty well, would be curious to have a nosey at it
