    Em0480 too coarse

    Hi all, sorry for repeating a topic already much discussed but I'm just hoping for some tips.

    I received a breville dual boiler as a gift yesterday (my first non capsule machine). I have an old em480 and was hoping to continue using it however the grind doesn't seem fine enough (using coffee roasted 10 days ago from local supplier).

    I have put an extra spacer under the bottom burr which didn't seem to change the grind at all.

    I plan on taking it apart and cleaning thoroughly tonight and I will also check that the top burr is seated in the collar correctly.

    Does anyone have any other tips?

    Thanks in advance, coffeesnobs seems to have a lot of users with a lot of helpful knowledge.

    Cheers.

    I have a EM0480 as well I used for decaf only and did have some trouble at first using the spacers/shims.

    Tips:
    Make sure you have cleaned everything very well before putting in the extra spacer(s). You need to get out all the old grounds in there before attempting to put in the new spacers.
    It's easy to not seat the top bur correctly. The first time I put a spacer in the top burr didn't seat correctly and the grounds came out like pebbles even on the finest setting.
    I needed 2 extra shims to get it close to fine enough for my machine, do you have enough?
    Use only the shims from sunbeam or the knock off variety used specifically for the EM0480 - using a washer of about the right size will only lead to disaster as there is very little play between far too coarse and jamming the burrs together. The shims/spacers are only about 1mm thick.

    You should be able to used 2-3 spacers/shims and get the burrs close enough to touch. Start by cleaning out the entire thing, top and bottom. Get out all the grounds & oils built up in there.
    Once reassembled (there are heaps of videos on youtube etc), go the the largest/coarsest setting. Start grinding with nothing in the hopper. Slowly wind back the setting until you hear the burrs start to touch - it should go from a 'normal' sound to a whine where they are just starting to scrape. Then you know you have the full range of coarse to very fine.
    The point where the burrs start to touch will be the 'zero' on the grinder which can be a reference point.

    then go ahead and try again grinding with beans etc. Keep in mind if you have done it correctly then you should now have a much much finer grind. where before you might be on notch 2 or 3, you might now be on notch 6-7 etc.

    Great advice above can't really add to it.
    But I will!

    I have had no issue putting in more shims, not sunbeam ones.
    Did this to my daughters one.
    Most recently I made a cardboard shim, put it between two existing sunbeam shims to adjust the grind on and EM 440. works fine! excuse the pun!

    Thanks for the tips. I had a spacer in there that didn't quite fit properly so I've removed. I'm waiting for extra spacers to be delivered. I gave the grinder a decent clean but still get very clean arse can't free on the finest setting.

    Fingers crossed the spacers era will work otherwise I'll be shopping for a grinder this weekend.

    Thanks Rawill, in the interim I've purchased some ground coffee from my roaster.

    Just to complete this thread. I received the extra spacers and installed them. As I pushed the top burr back in the locating ears snapped off so now the top burr is loose.

    I'll be buying myself a new smart grinder pro in the morning. yay.

    OUCH, Goodness, I have only done 3 grinders, 2 480s, and a 440, but never had that happen. I wonder what went wrong.

    Pity we weren't closer, I would take a look.m I guess you are in Aust.
    I am sure the holder for the top burr will be available.

    Otherwise you could post the spacers to me!
    I would take out my cardboard spacer then!

    All grind chamber parts in the 0480 are replaceable, but if you can get a BCG820 on sale then it might be better value than spending between $50 and $100 on 0480 parts. Don't throw the 0480 away, someone here will want it I'm sure.

    It's a moot point now, but just a little addendum to what WEBN said above - the Sunbeam shims are actually 0.25mm thick and you can usually add up to 5 or 6 in total before the grinder stops coping. If it needs more than that then it really needs new burrs.

    For future reference, and anyone else reading, don't follow Sunbeam's instruction on top of the burr that says "Push top burr firmly into place" because this exact thing can happen.

    The easiest way I find to install the outer burr is to seat the burr lightly into position by turning it around until it drops down slightly and stops turning. The white marks on the outer burr and grinder should line up.
    Apply light pressure with two fingers on opposite sides of the burr whilst turning the grind adjustment collar clockwise. It doesn't need a lot of pressure to achieve this.

    You will feel the outer burr drop down further and once the collar has clicked back into position, you should be able to see the outer burr moving up and down when you turn the collar.

    Thanks for the responses, I had the top burr sitting in properly but each time I reattached it, it would pop out. The locating plastic seemed rather warn so I guess that's why it was having issues.

    Anyway, I now have a smnart grinder pro and am making coffee better than many of my local coffee shops.

    Pity it didn't work out for you mate

    However I am sure the upgrade won't go astray anyway.

    Ahahaha, sounds like you're wife and my wife have the same suspicions! Well the Breville combo will work well together.

    Unfortunately the resale on the EM0480's aren't huge even for the working ones, but you could always offer here if anyone wants any parts. Or keep it as a fixer-upper for decaf or a back up.
