  • Faulty 6910 ?

    Hi all,

    Ive had my 6910 for over a month and after doing the coffee appreciation course, Im feeling that my machine is not performing the same. Ive got the em0480 and still cant manage a 25 sec pour. At the course I was able to pull good consistent shots.
    Im using fresh beans and dosing and tamping to what was suggested at the course. The only time that get the same quality shot as at the course is getting the gauge into the red and usually the manual shot cuts out. If I go a coarser grind the shot comes out blond and soggy pucks . I have tried my adjustments on the grinder at single increments. I have it set at the moment on 16 considering the grinder now 12 months old. Any less than this machine chokes.

    Any ideas ?

    Im using a 6900 at work and always aim for about 1/4 way into the red.
    A little bit further does sometimes cut out as I also use the manual button.
    Using between 15 - 12 (EM0450) depending on bean freshness.

    Did they not go into the red at the course?

    Can you notice a difference in grind size say between 16 and 20?
    Im wondering if at 12 months old its a little sloppy and there may not be much difference.

      At the course the gauge was in the middle of the brown and that cosistency was like honey. Im not that unless I go into the red ..

        Ive heard that, but also read that many others find the same as you when they get home.
        Sunbeam supposedly deny their machines at the courses are anything other than standard but as an auditor weight of evidence suggests otherwise.

        You can always ring them and see what they have to say.

            Soggy pucks normally point to underdosing which is also one cause for fast shots, so Id be asking the same question as Mal.

              What I noted, when I did the Sunbeam course, was how quiet the demo machines were. When I use mine it makes a racket. (Although this might be because my kitchen is small and their room was large and carpeted.)

                The room that I did my Sunbeam apprecation course was actually a hotel conference room, so the noise levels would naturally be lower.

                My kitchen has a big glass splashback and stone surfaces everywhere so its perfect for bouncing the machines noises everywhere.

                  Back to the point re the espresso dial.

                  I find that my coffee had a distinct burnt taste when I grind too fine and this causes the gauge to point into the red.

                  I like my coffee best when the dial is around where the golden triangle ends and the brown section starts.

                  The puck comes out nice and dry with a hint of steam, and when I bang it out, the filter basket is shiny clean. Aahh, just perfect coffee every morning, and quite easily reproduceable day in day out.

                  One thing that I really like about the Sunbeam EM6910 is that its a very consistent machine and doesnt take long to get up to temperature when I first turn it on in the morning. I guess thats the beauty of a thermoblock. It only heats up just enough water for what it needs.

                  The energy costs of running a Sunbeam EM6910 in a domestic environment where its used maybe once or twice every day must be significantly lower than a boiler based espresso machine.

                    Called Sunbeam today and they are going to send me a sample of coffee ground which is supposedly the right grind... The indication is that grinder is net set correctly, they suggested that I remove one of the three washers from underneath the bottom burr. I do find at times the difference between girnd setting to big. I have been thnking whether I should be looking at a Rocky ..

                      Nice of them to do that but the right grind will depend on the bean and its age, and of course what they send will be stale by the time it gets to you even if it was freshly roasted when they posted it. But I guess it will demonstrate the point if youre currently grinding for drip or plunger or something, and you have to admire them for once again going the extra mile to provide support.

                          Ok, I tried up doser and this time only halfway into the red and decent crema. Ive removed 1 of the 3 washers as also suggested so Ill give that a go too. Ill post my results

                            Ok, I removed 1 of the 3 washers and the grind was way too coarse. Similar to that of freeze dried coffee . So replaced the washer back again so I have 3 in total. Taped the the top burr as per Ray C posts and now have a decent grind again. Now gauge is going to the start of the brown section and not choking . I believe my issue is the grinder as its 12 months old and probably sloppy. Id like to follow Ray C suggestions , just need to find out how I can create the bush without having access to a lathe... :-?

                              If its still under warranty, ask Sunbeam for a replacement. Theyre very good that way.
