    Too Fine a Solution for a EM0480?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    THIS FIXED THE PROBLEM I HAD WITH MY SUNBEAM EM0480 GRINDING WAY TOO FINE, SINCE NEW 2MONTHS AGO.

    I point the finger at the top burr, as being the culprit (it least in the too fine brigade, I think).
    I found, when the top burr was removed from the grinder (with the help of a bright halogen lamp up close) that metal top burr was misaligned in its plastic housing when viewed from upside down.
    One side of the burr metal ring is flat, with a complimenting flat guide built into its plastic housing.
    The metal burr was twisted slightly, so the two flat surfaces were not meeting squarely, AND the burr was sticking out slightly above the plastic rim of its housing.
    With a flat screwdriver and a tack hammer I gently tapped the burr out of its housing. Rotating as I went.
    I cleaned both pieces thoroughly, removing the accumulated grind.
    I then carefully placed the metal top burr back in its plastic housing, making sure both flat surfaces are squarely aligned.
    This time the top burr is BELOW the plastic rim of its housing (i.e. when viewed upside down).
    Reassembled the grinder, aligning with both sets of arrows mention in the instruction booklet, and thats it!
    This time the grinder can grind at a reasonable volume at 1 (for Turkish) (where nothing was coming out before) and close to the normal range for espresso.
    And yes, coarse is coarse at 20 and above!
    It worked for me. I hope it works for others.
    Phil
    p.s. Dont attempt if youre not confident, of course. I could supply photos later.
    I HOPE YOU FIND THIS HELPFUL.

    Sounds like a job well done Phil.

    Do you put the original problem down to poor quality control at the manufacturing stage?

    Yes, but you try getting Sunbeam to admit too it! *
    I spoke to their help line a few days ago. I mentioned the Coffee Snobs forum members are having problems with
    the same EM0480 grinders. *She seemed to be aware of the CS website and advised all the machines theyre getting returned to them
    only have problems with the collar and top burr not being reassembled correctly (aligning with the arrows).
    I pointed out, that Im on my third EM0480 after the previous two developed the opposite problem over a few months each.
    Without saying so exactly, they seem to blame the users rather then, I think, their quality control in assembling certain parts of the EM0480.

    Hi Phil,

    Ive had someone bring me an EMO480 from Oz to Singapore, and I think Ive got the same problem that you seem to have fixed here (on another thread someone posted a pic with the arrow pointing off the range, past the coursest setting, to get a decent espresso grind, that exactly described where Im at). So fixing it myself is a better option than taking it back, at this point.

    Im grateful for your fix. I wonder, can you post the photos you suggested you might be able to supply?

    Best,

    Michael

    Many thanks, Phil. I look forward to them.

    All the palaver about this grinder is quite amazing. Sunbeam seems to have struck some kind of "vein of value sense" with this product. Sort of gets to the independence of mind and taste that needs to get just the right shot; and players in this market would apparently rather think and tinker than simply spend.

    Best,

    Michael

    Hi Phil,

    Dont worry about the photos. I just followed your steps and it was easy to identify exactly the same conditions as you describe in your post above. The misalignment of the top burr could easily looked like it was supposed to project over the plastic housing a bit. And the misalignment of the flat part of the burrs diameter with the housing was really hardly noticeable.

    Very nice observation on your part, and deft action in response.

    Youve saved me a lot of bother - thanks.

    Michael

    Re: Too Fine a Solution for a EM0480?

    Ive found this same issue - which is real bad luck because this is a replacement machine for a week-old 0480 which was grinding too course (it has to be cranked to 4 to get reasonable extraction). Now I have to wind back to 23/24, otherwise the coffee maching simply cloggs up. The product manager is going to call me tomorrow to talk me through a solution!!! I imagine it wont involve bashing bits into shape.

    Not sure about the bashing bits into shape bit, but of course it is best to work with Sunbeam for resolving issues while under warranty. ;)

    Thanks Phil. Did you ever take pictures of your "repair"? If so, it would be great to see them as I am not overly confident the product manager will be able to suggest anything sensible. My other option, I suppose, is to take it back to the store and try and swap it over again!!!

    Youre well within the warranty period.
    Take it back.

    I may well resort to doing that as Sunbeam havent got back to me. When I called today, I was told the coffee marketing guy is looking into it and will try to get back to me.
    Ill give them another day before taking it back. In the meanwhile, Ill carry on grinding on 24!!!!

    Um, if your not going to use the grinder for Plunger then Id leave it as it is...

    The Marketing guy is actually a great guy and very helpful - he is a very busy man though...

    Re: Too Fine a Solution for a EM0480?

    I have to say that an EM0480 that grinds too fine is a much better beast than one that continues to get coarser and coarser. *I replaced mine last November when it became too coarse on a setting of 2, the replacement was one that grinds too fine. *It seems to be stable - there has been no deterioration in the grind in 10 months, though its only used for decaf now, once or twice a day and on a setting between 23 and 28. *So Id agree with MarcS, if you only use it for espresso keep it as it is.

    Re: Too Fine a Solution for a EM0480?

    Id consider that, but even at 25, the grind is way too fine - the machine sometime chokes or delivers a trickle - nowhere near the 30ml in 30 seconds. Sure, if it was a bit on the fine side, I could live with it, but this is not acceptable.

    Flatwhite, are you aware that even though there are 25 calibrations marked on the EM0480, it actually has 32? It will go 7 notches further at the coarser end. Ive never been sure why they arent marked on the collar, but they are there just the same. :)

    Re: Too Fine a Solution for a EM0480?

    Just a thought. Could the beans affect the fineness of the grind. I just opened a new bag of Jacques (Qld-grown) beans which are perhaps not as fresh as the last batch. Could this be affecting the grinder. Basically, at 15, nothing happens - absolutely nothing comes out of the grinder. A trickle of fine poweder starts at around 21, and I have to grind pretty much off the scale at 26 to get a flow from the coffee machine. So, would less fresh beans have this sort of impact?

    No, the opposite mate... the older the beans, the finer you grind them..

    Re: Too Fine a Solution for a EM0480?

    Sunbeam called with the solution: remove the bottom burr and take out one of the spacers. Mine did indeed have three and it seems to be much better with two. I may even try just one!
    If anyone else is in the same situation, save yourself a lot of time by simply removing the burr (the nut needs to turn COLCKWISE) and remove a spacer - a two-minute job.
