    EM0480 Help

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    My First post.. ;)

    Well,


    I recieved a new EM0480 grinder to go with my 6910 for Christmas.
    I took it out of the box, Great! beautiful and shiny.

    Got some fresh beans and ground them into the portafilter, they looked ok (had the grind on about 13). But when i brewed the espresso, no coffee came out. :-? I made the grind a bit coarser until i eventually found out that there was no difference in the grind no matter how course i went on the dial. I cleaned the grinder thoroughly, and assembled it again. Aha! the grind was coarser. But it wont go any finer now!

    Should this be happening with a brand new one? Im planning on calling sunbeam tomorrow but thought Id see what people have to say here first.

    Thanks for any help!

    sounds like the top burr carrier isnt being seated properly.

    Twist the collar around (coarser) until it wont go any further, then press the button on the back and keep twisting until the arrow on the burr carrier lines up with the arrow at the back of the grinder. This should enable you to take the collar assembly off altogether.

    Now take out the top burrs (there should be a small metal handle on the burr carrier that you can use to twist the burrs) by turning them and pulling at the same time.

    Now, place the collar back on the machine so that the arrows line up again. Next place the burrs in the collar and then rotate with gentle downward pressure, they should then fall into place. Do not continue to try and turn the burrs. On a new machine, there should be arrows / marks on both the burr carrier and the collar that line up when the burrs have slotted in correctly. Now turn the entire collar back round. This should have the burrs seated correctly into position. You should be able to look into the top of the burr assembly and see the gap between the top and bottom burrs widen / shrink as you make the grind coarser / finer. The movement wont be much each click, but a few clicks should make a visible difference.

    Some other possibilities / thoughts -

    Are they fresh beans (from a local roaster, not the supermarket)? If from a supermarket, they will not be fresh and you will struggle to get any sort of decent espresso shot and / or consistency of grind.

    How much coffee do you have in the hopper. The 480 likes to be roughtly 1/2 full of beans to provide adequate downward pressure on the beans as they pass through the burrs.

    Is your dosing / tamping routine the same for each grind? When trying to get a decent shot, and something goes wrong, only change 1 thing (usually the grind), keep the dose (amount of coffee) and the tamp (pressure) as close to the same each time as you can.
    Are you getting the same level on the 6910 tamper each time (1/2 of the steel above the rim of the basket).
    Have you taken out the pressurised filters from the PF and using the standard filters?

    The pair of the 6910 / 480 is capable of making wonderful coffee when paired with a little knowldge, a lot of passion and (some say) most importantly FRESH BEANS

    wow, this is the 2nd one of these in as many days (another thread 6910 / 480 help). I wonder if Sunbeams QC went a little laxed rushing out all the "free" grinders recently

    Re: EM0480 Help

    The other thing you can try is removing the collar (as per above) and then remove the bottom burrs (using a spanner, turn the nut on the top of the burrs clockwise to loosen it - you will need to wedge something around the burr to stop it turning).

    Remove the burrs, under these there should be some washers. Remove 1, then replace the lower burr and put the nut back on and reassemble as per above.

    Try again, it could be that the burr was sitting too high to begin with (too many spacers). My machine used to grind around 18 - 23 depending on bean age and volume of beans in the hopper. After removing 1 washer, it now grinds around 15 and is pretty consistent at that setting.

    Here is a calibration guide from Sunbeam showing Senators suggestions:

    But as its brand new, I think youd be better to return it for replacement.

    Re: EM0480 Help

    Hi, FYI I received my grinder by redemption just before Christmas and tried it the other day and got the same results.

    Very fine grind for a short while would come out (only about 1/20th of required amount), then the it would not come out, and at opening the unit all the coffee would be compressed in the unit/grooves. No idea whats going on..

    To me, all the coffee needs to do is fall through but it fails this, also setting the grinder to 20 changes nothing, so likely the exact problem as original poster.

    I tried opening / cleaning and reseating things also, but same results in the end. I will also call sunbeam.

    Adam

    *Update* when removing bottom burr, I only have 1 spacer washer under the burr, is this about correct?

    **Update*Update** After replacing everything and leaving the grinder on the maximum setting (eg a little past 20 [it still clicks past 20]) I managed to get a grind through OK, it was actually quite fine the grind even on 20...

    I also noticed that the hopper doors were not opening cleanly all the time (perhaps coffee in them) so this is something else to be sure of.

    The hopper door thing is not unusual. I had three machines and all had quirky apertures - but it didnt affect the flow. In your case, sounds like something more serious.

    Re: EM0480 Help

    Well it seems i too am having the same problem with the grinder i received as a bonus with my 6910. its coarse all the way from 0 to 20. It does get finer towards 0, but not fine enough.

    i got a couple of washers from Sunbeam and added both, but it made no real difference.

    as i received it as part of the bonus offer, would it be covered by warranty? i dont have a receipt for it...

    cant work it out, and am wasting a lot of coffee. :-(

    might need to call them again to sort this out...

    Re: EM0480 Help

    Call them.
    It should be under warranty and make sure you tell them how much coffee you are wasting.
    If it were me Id be asking for a free seal to make up for your wasted coffee.
    You are going to need it eventually.

    Be subtle though, dont ask for it outright, work your way around to it.

    Re: EM0480 Help

    its really sounding like there was a batch of dud grinders with so many problems reported around this time.

    Nothing takes the shine of a new xmas pressy like the dissapointment of it not bloody working properly..............

    I got mine (for my birthday) about 3 weeks ago. *No problems at all. *8-)

    We were buying freshly roasted beans from a local roaster but, without a grinder of our own, had to get him to grind them. *I know this isnt a top line grinder, but we are loving it. *:D *:D

    Re: EM0480 Help

    I just got an em0480 a week ago from harvey norman in nz.
    I had the same issue with the grind being way too coarse. I rang sunbeam and they sent me the washer kit. I undid my grinder to find that there were NO washers in there at all!! (isnt there supposed to be at least 1 or 2??)

    I put the 2 in from the kit. Now im happily grinding away for espresso machine on the 12th click setting. Even after this drama I still think em0480 is cool, and I am getting good results.

    Re: EM0480 Help

    I seem to have the inverse happening.. *When I first got my 480 I had to set it on about 17 or so to get a good pour. *now, (six months later), I find I am continually adjusting higher to maintain a decent pour.

    I am using beans from the same source and a spring loaded tamper for consistency... *I have taken the upper burr out to check for any sign of mis-alignment, etc.. withno luck.

    What would be causing me to have to always increase the grind size?

    Thanks!

    Re: EM0480 Help

    Have you cleaned the grinder?

    Take it all apart and use a dry brush to get all the gunk out. I find that it doesnt take long for a layer of coffee dust to get caked on to the bottom of the upper burr, this may have an effect.

    Other things that can effect it also is the volume of beans in the hopper. The 480 does not like the "just enough per cup" method (popcorns terribly and retains too much in the grind chamber). When my 480 was grinding in the range that you have (17ish), it was very changeable like you describe with the coarsness varied depending on the volume of beans in the hopper (less beans meant coarser grind required), age etc with the grind required going anywhere from 17 - 22/23). When I remved 1 of the washers to get the grind range around the 14 - 16 mark it is much more stable and only required a click either way periodically or when going from the double shot to the single shot filter.

    Re: EM0480 Help

    I have Gaggia Classic /EM0480 Grinder for 11 months. Apart from a few teething problems *all fine until about three days ago. Initially following usual grinding and tamping procedures the flow was very dark and fine and extremely slow. I checked shower screen and holding plate on Gaggia and they were fine. I cleaned Grinder top and bottom burrs and noticed no spacers or washers below bottom burr although didnt seem a problem in the past 11 months. Now after cleaning the Grinder the grind *seems much coarser (some chaff like particles) - Have tried a number of different settings but now the flow is like a tap(coffee horrible) wheras the tamping technique hasnt
    changed. I am sure the burrs have been reassembled correctly. As the Grinder warranty runs out end of next month I have sent Grinder in for service. *It will be away for 7/10days.

    However I would appreciate anyones comments on why the flow would go from a a thick dark dribble to a water like consistency from just cleaning the Grinder. I dont think it is the Gaggia - it must be something out of line or broken on the grinder ??

    What are your thoughts ?

    Thank you
    Les

    Re: EM0480 Help

    What an awesome site!! Big thank you to the organisers!!

    Am also experiencing an overly coarse grind from my EM0480 - even on 1st notch. Sunbeam have suggested I try ramping the setting right up to 20 and trying again as there was a batch of grinders that had a calibration issue. I tried this and got a hideously coarse grind which poured way too quickly. Sunbeam said if that didnt work to ring back and get a washer kit...guess what I am up to tomorrow? Will report back how I get on...

    I still love the EM6910 and the grinder, regardless of issues - best coffee I have ever made. *Also I cant recommend coffee alchemy enough - a friend put me onto them - small roaster in Enmore. They roast to order and send out the best blends I have ever tasted! *:D

    Hi there!! Great site guys!

    The "burr shield" that sits the hopper of my EMO480 has broken off. Should I get a replacement or does it not matter??

    Re: EM0480 Help

    I seem to be having a similar problem to some of you guys. My sunbeam EM0450 started out well with pours ranging from 20 to 30 sec on setting 12 using espresso wow beans from this site, have changed to sulawesi beans from this site and having a 10 sec pour even when I set the grinder on 2. My dosing and tamping remain standard.

    Thanks carriek for the instructions, Ill be checking the washer setup this weekend and hopefully back to a 30sec pour.

    Sort of OT--450/480 troubles

    I have a couple of friends who want a cheapish grinder that will actually work, and the 450/480 used to be a easy recommendation.

    Is everybody having these sorts of issues? or at least enough to change the recommendation? What options are there around the $150 mark?

    At around $150... *You got no other choices...

    1: EM0480 or EM0450 *as entry level
    2: Base level Rocky
    3: The best you can get $ may well = the $ of the coffee machine *;)

    Over all there has been few if any real problems with the Sunbeam grinders... *( Bite people bite).

    That is not to say; that they do not have a very interesting, but easily fixed QA problem ? ...

    What I tend to see, is that some are great and stable, while others take a little while to bed in...

    That is, that while teh burrs are metal and of reasonable quality (@ this price range) they are mounted in a grinder that is in all sense - plastic (they all are at this $$$). *Thus depending on who was setting up / testing / adjusting.... *It is not uncommon to find that as the burrs settle, the grind settings are then out of wack.

    Fix... *A washer or two under teh bottom burr - Sb supply or make ya own. * A 5 min job for some people, for others; any repair is a return under warranty and a big Whoo Harr...

    Of the 4 I have adjusted and have used *etc (One at work gets a thrashing) once adjusted and bedded in... *Not a problem...

    Oh... Except for when people might try to clean and put things in back to font or just stuff up big time... *However that is a PEBKAC issue not teh machine...

    Now two users have moved on to Rocky grinders and it is strange that they *both say they likes the EM0480 better and felt that they could get a better grind and finer...

    Well I didnt manage to get around to opening up the EM0450 on the weekend but on the finest setting (1) I did manage to sort out my grind a little better. I think AM has a valid point, a little settling of the burrs has happened and Im expecting the washer to fix the problem, just waiting to empty the hopper a little more (classic procrastination at work).

    I just drink more coffee :-)

    Also try not to leave beans in for more than an hr o two... We always just add the amount we need.

    Otherwise they will go stale and you will have to grind finer to get any thing from them.

    It has a self closing gate.
    If you take it off therell only be beans left around the burrs.

    To thundergod ..... boo, youve just taken away my procrastination excuse ;D

    Anyhow I stocked up yesterday with three 4mm, three 6mm and three 8mm washers in preparation for battle with the 450. After 5 minutes all going well, top burr removed, collar removed and bottom burr removed (clockwise is the key)...... then we hit a dilemma, spacer is 7mm >:( not the most common washer size around!

    So currently the grinder is disassembled and awaiting my trip to the local hardware store to find a 7mm spacer.

    After all the rant though the EM0450 is very easy to disassemble and poke around in or mod, a definite plus for the machine.
