  • Problems with EM6910 or EM0480 ??

    Sorry in advance if a similar thread already exists!!

    I have been using my EM6910 for over a month now and I feel as though im not getting the best out of it. I had recently purchased the grinder and although this had improved the taste by more than 100%, I feel as though I cant get the grind fine enough.

    The problem I have is when I set the grind to the finest setting and tamp it down with considerable force, I barely get the pressure guage to hit the yellow marking. This is when I use the two cup basket(not the dual wall). In most cases the pour begins halfway before it gets to the yellow marking but slowly creeps there eventually. I would say the pour takes about 10-15 seconds.

    This has been the case even when using 3 different beans. So far the best beans I have had are the Gravity, Lavazza and Grinders. Yes I know these are supermarket specials and most probably stale beans, but they still taste much better than ground coffee packs that I was using before I had the grinder.

    I wanted to experiment with the single cup basket (not the dual wall one) because I read somewhere on here that the extraction is better. Well it is true because the pressure guage went beyond the yellow marking and almost into the red. The pour lasted much longer and looked so much creamier and but unfortunately there was some leakage around the group handle. It did taste better but another downfall was the coffee ended up all over the group head and not in the basket after the pour. :-[.

    Now just a couple of questions;
    Is my grinder no good, I know not every EM0480 grinds the same ??
    Have my seals busted because there is some leakage whenever there is more pressure ??
    Is this all because I am using supermarket crap beans ??


    Thanks

    Hi Ken,
    Ill leave the other 6910/0480 owners to do the talking on them, but as far as your last question goes - yes.

    How hard are you tamping? You should get the bathroom scales out and measure that. Maybe youre tamping too hard for the fineness of the grind. Check that out and see what you get, maybe you can back off the tamp pressure and coursen up your grind.

      Using the double cup baskets;
      If i dont tamp it hard on the finest grind then it doesnt build up enough pressure and the coffee pour is quick.
      When I grind on a courser setting and no matter how hard I press the coffee, there is hardly any pressure...

        Hi Ken. As yeeza said, your first problem is stale coffee - untill youve addressed this, it will be difficult to determine whether theres anything else going wrong.

        That said, it would be worth disassembling and cleaning your grinder, in particular make sure that the upper burr carrier is seated properly. Reassembled but with the hopper off, look at the burrs as you slide the collar to the finest grind position; the burrs should almost touch.

        Re the leaking from the group; make sure you clean the group head, showerscreen and group head seal after every shot; a folded-over (clean) kitchen cloth is useful to get into the gap around the group head. Its also possible that the group head seal hasnt worn in yet; mine leaked quite a bit at first but softened up with use, which then allowed the portafilter to lock in further and seal better.

          Yeah I seem to remember people saying that having a clean group seal is crucial on the 6910s (as well as most other machines but more so 6910s). They leak easy, if theres grinds in the way.

            If you In Brisbane, give me a PM...

            A: Get GOOD Beans
            1: The grinder may be out of adjustment
            2: Clean is issue for seals... Flush / wipe and keep clean (Easy and not a prob once you get in the grove)
            B: Get GOOD BEANS
            3: Should easily get to 12:00 on the dial (I tend to like 1 to 2 with 3 at the very limit.
            4: Knowing ya grinder and the quality of the beans is the main issue that I have seen

            Let us know how you go.

              Hi Ken I have both of these machines and find you need to have a coarser setting for the single filter basket,than you do the double.But there is no way I can grind on the finest setting, I generally have the grinder set on 19 for double and 21 for single and get about 25mls in 25 seconds.If im not happy with the result I start again, eliminating one thing at a time.For example have grinder on say 19 the pour is to fast you can try tamping a bit harder or adjust your grind.
              But do one thing at a time.You might find you can get better results with doubles rather than singles , I generally do.
              Also if you havent done so do the course it can help

                    I wouldnt admit to that.Not a fan of Grinders. Just browse through beanbay brown order some espresso wow and you will probably get it the next day . If you cant wait, Veneziano is in Abbotsford, a couple of local cafes near me use thier coffee  and it is good.
                    You can also try Coffee Hit they have a melb address but i havent tried any of thier coffee.
                    The problem with Grinders is they are to big and you rearly get fresh product.
                    Remember once roasted coffee goes stale within 4 weeks if stored properly.
                    There are quite a  few good roasters in Melb but with the site posting rules we cannot mention them here

                      It is quite possible your grinder is out of calibration from the factory - I had the opposite problem - my 0480 was way too fine.

                      Once you have tested the machine with fresh coffee that has been ground by someone else to an espresso grind it should become more clear.

                      I returned my machine to where i bought it and got a new one on the spot because it did not work the way it was intended from the beginning.

                      I use a setting of between 13 and 14 depending on the beans on my em0480

                      Both in the course and the dvd they only ever recommend using the double shot basket

                      Have you called Sunbeam and discussed the problem with them?

                        Thanks for the feedback!! I have noticed an improvement now that I tighten the group handle allot more!! Crema pour is sensational!! But I still have to set the grinder to 4 or the finest setting to get decent pressure. Maybe I should give sunbeam a call!!

                            I actually have my grinder on 4-5 as well and I get a great pour with that. I think that every grinder is a little different. My friends got the exact same grinder but when he sets it at anything under 10, nothing comes through at all.

                              At the risk of repeating what has been said a fet times - have a look at this post http://coffeesnobs.com.au/YaBB.pl?num=1200304807 Depending on the set up and age you could be any where on the scale.. It is a matter of trial and error and then keep an eye on things..

                              I have a washer in mine and depending on beans any where from 14 - 20.. Before the washer, it was about 2 - 4.
