    EM0480 Grind Not Fine Enough?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi All,

    I have recently bought an EM0480 grinder (To go with my EM6910) and I am finding that there is very little variation in the grind whether its set on 0 or 25? When set on 0 its far from turkish. Extraction time is about 8 seconds and the pressure bar stays below the "recommended range" shown on the guage.

    Id been using pre-ground coffee in the past which had much better extraction times and was in a good pressure range.

    Ive pulled it apart and cleaned it as per the instructions in the manual and nothing looks out of place?

    Is there any other way to adjust the grind aside from rotating the ring? And if Ive got the bean hopper off, should I be able to see any physical movement when rotating the ring? (Because I dont at the moment)

    Thanks in advance.

    Shannon.

    Welcome to Coffee Snobs.

    Ive sold my Sunbeam grinder so cant look at one now, but from memory if the top burr isnt positioned correctly you will have that problem.

    I know it might sound dumb but did you line up the marks when putting it back together?

    Also, did you notice if it has any washers under the bottom burr?

    If you have the hopper off you should be able to see the bottom burr rise (or is that top burr lower?) i.e. gap get smaller, as you move the dial from 25 down to 0.

    Yeah it is the top, or outer burr that will lower.

    On mine when the top burr is put in place, the burr and burr carrier sit proud. As you wind the collar around to the 10 to 15 range the burr carrier has lowered to below the hopper assembly area.

    After cleaning I use this as a check that is back together properly.

    If this is the case and you still cant get a fine grind then I suspect you need a washer or two under the bottom or inner burr.

    Hope this helps

    Chris

    If the burr is seated properly on any grind setting you should be able to pull the little wire burr carrier up firmly until it "pings" and flies out of the machine.
    You may need to also unscrew the lower burr, and check if there are two or three spacers underneath. Sunbeam will send you more if you need them.

    Thanks Everyone!

    Ive checked the alignment marks and I can see a slight movement (Gap closing and opening) when rotating the dial.

    When the top/outter burr is in place it sits slightly (~.5mm if that) below the burr carrier.

    I havent taken the lower/inner burr out yet to check what washers are installed. Thats my plan for this afternoon.

    Thanks again for the input!

    Shannon.

    Hi All,

    Is there any trick to getting the nut off the top of the bottom burr? ie. How do you stop the whole burr from rotating when trying to undo the nut? (I dont want to damage the burr)

    Thanks.

    trick to getting the nut off the top of the bottom burr
    Hi Shanmc. The first trick is that it is a reverse thread ie turn clockwise to remove the nut.

    The highly technical but sunbeam prescribed way of stopping the burr turning is to wedge it with a screwdriver.

    Re: EM0480 Grind Not Fine Enough?

    Just an update, made a coffee after putting the grinder back together the same as I pulled it apart ie. Just the two washers that were already there and the first grind was too fine for the EM6910! I bumped the grind setting up to 7 and got a pretty good result. (Will fine tune over next few coffees)

    Ill monitor it over time, but initially it seems that taking the nut off the bottom burr, taking out the burr, then putting it back on has helped.

    Did you need any more washes to get a good grind?

    That sounds very similar to mine.
    I grind on about 13-14 but mine has 3 washers
    Sunbeam reckon that each washer is worth about 7 clicks on the scale

    Re: EM0480 Grind Not Fine Enough?

    i just did this mod on my emo450 which has the same burrs as the emo480. just contact sunbeam and they will send you out some more washers. the even included an instruction sheet on how to remove the lower burr and add the extra washer - they must get this problem quite a lot. i must say i was impressed with their customer support.

    im now grinding around 13-14 on my gaggia classic.

    Hi all,

    As stated in another post I managed to pick up an em0480 today, but have also found that the grind is too course.
    Think I will have to contact sunbeam tomorrow to get hold of some washers.
    Will see how I go.

    Re: EM0480 Grind Not Fine Enough?

    Hi Guys,

    Im kind of new to the forum.
    I have a sunbeam 6910 and the EM450 grinder.

    Apart from the stupid deal where if the 6910 looses power for a while once power is restored it runs in the off position for 30 minutes, everything has been fine.

    I did start to get sick of the course grinder though and have been thinking for a while I should just throw in the towel and buy a better grinder but after reading your tips on here for pulling it apart and giving it a go my self the grind is pretty good now ;D

    Great tips guys!

    Sounds like you guys just saved me a fortune. I am going to try the screw/washer thing on my EM480. Ive got to find the screws first. My hubby will be worried about breaking it. Is it a fairly easy job to do.
    Thanks for the info :o

    There is no screw to find... What you need is the washer to go under the bottom burr.

    I will find one of the other posts that has pics and it may be easer for you to follow.

    Go Here.. http://coffeesnobs.com.au/YaBB.pl?num=1244882145

    Have a read and Rusty has even posted an attachment...

    Same topic but people dont go looking first; thus often the same problem in lots of posts and that makes it hard to find teh answer.

    Re: EM0480 Grind Not Fine Enough?

    Thank you for your help it would have been perfect but I probably have a bigger problem. The E480 when I looked CLOSELY in daylight is actually 430 so I probably do need to spend the money I was going to try and talk hubby into anyway. I will check for anything but Im pretty sure I have to go for it.
    Thanks Dawn :(

    As far as I know the 430 and 480 are mechanically identical. The differences are electrical, cosmetic, and warranty.
