    SB Emo480 & Em6910 under extraction & grinding

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

    I have been using my EM6910 with pre-ground coffee until my grinder arrived, and have pretty OK results...but now that the EMO480 grinder is here, I can not get a good coffee. *

    I changed the filters to the standard type and generally use the single filter. *I am only making one coffee every day or so...cos its so bad, Id rather go out!!

    It is watery, weak and without crema. *Also, I tested the flow and it is super fast 30ml in 10 secs or so...and finally the gauge does not get out of the 1st white section.

    All in all, not the result Im after!!

    I have tried grinding my whole beans from 12 - as per the instruction book, *all the way down to 1 and on all grinds it looks too course (in comparison to coffee ground for me).

    My coffee beans are commercial quality purchased in bulk for my husbands restaurant, but I would doubt that they are as fresh as 3 days old..as I have read in other posts.

    Also, I have tried dosing up and down...but have found it I put to much coffee in the it is hard to fit and leaks...

    So, a bit of a novel...but any suggestions? *I have looked at other posts but did not see the same issues as mine.

    One last question re the grinder, any tips for not making a mess, as I am grinding straight into the PF.

    Thanks in advance.

    Hi Donnan,

    Welcome to CoffeeSnobs.

    Im not an expert on the EM480 although a friend has one. Assuming the beans are fresh (less than 3 weeks from grinding will do--and please dont assume that commercial beans are fresh) two issues pop to mind--the single basket and the grinding!


    1. The single basket is very hard to use. Try the double basket, fill, and either pump less water through the grounds (a "ristretto") or put the extra in the fridge for an iced coffee.

    2. If this doesnt give you good cup, and the pour is still much faster than 60 ml in 30 seconds (this is a guideline only) then Sunbeam has some spacers for the grinder to make the grind finer. A search of the website here will find lots of info on this.

    Along with the spacer kit you can ask for the silicon spout extension which reduces mess.

    Good luck.

    Greg

    Check that the grinder is assembled correctly. The white dots in the inner section need to line up with the outer part. If that fails, adding a spacer is easy - just ask Sunbeam for an additional washer and some instructions. It takes a few minutes and the results are instantaneous.
    Good luck.

    I would look at the beans first, are you able to find out how fresh they are. If you cant, try some from a local roaster first. Any and all fixes advised would be useless if the beans arent fresh. If they are fresh (1 - 3 weeks old) then you will need to look at other factors (burrs seated properly, adding a washer below the burr etc).

    To seat the burrs after I have brushed out my 480, i put the collar back on to the grinder and leave it (dont turn it to lock it in), I then take the removeable burr and place it on top and rotate it around until it slots into place (the marks on mine have long worn away, so I dont have the arrows to line up anymore). Once it drops into place, I then tighten the collar until around the 15 mark. You can visually check if it is seated correctly when you tighten the burr carrier, you should see the gap between the two burrs decreasing.

    If you cant see a visible difference in the coffee between 1 and 12, it sounds like the top burr isnt seated properly, but as mentioned, if the beans arent fresh, then you are pushing shite uphill with a rake trying to get a good brew

    Thanks, I checked the assembly, and it certainly looks like it is seated properly, in that all the arrows align etc..but I can not see the burrs move closer or further away as you change the grind setting...so something seems to be up there.

    The grind is fractionally courser at 20 than it is at 1, but I would expect it to be much finer at 1 than it currently is.

    I will ring SB after on Mon and see what they say...seems like the similar problem to the next post...

    Thx.

    Re: SB Emo480 & Em6910 under extraction & grinding

    Any luck so far?

    Ive got the exact same problem, received my grinder for Christmas - in fact, I was so excited about grinding my own coffee, I had asked my partner to do a gift exchange pre-Christmas and when that failed, I woke up at 4am, ready to brew. Needless to say I was pretty dissapointed.

    Ive taken everything apart and put it all back together. No luck, no difference between 20 and 1, all the size of small rocks. Im having to use the double floored/pressurised filter as I only have whole beans and no local coffee shops open to grind for me.

    Anyway, my beans are fresh from Epic Espresso, they are 3 weeks from roast date - still smell very sweet. I rang Sunbeam and apparently they are on leave until the 5th - Im not sure that the number is the same on the website as it is on the waranty card, Ill have to double check.

    Ill be annoyed if it is...

    And another with the same problem !!

    Waited 3 months for mine, have to grind at 19 and a very very light tamp !! Friend of mine has one and uses the same beans (Rio espresso) and grinds at 13-14. Mine has the two spacers so i tried taking one out, that made it coarse but then could not get it fine enough !

    Tried the recalibration and that did not help either :( will have to contact Sunbeam i think

    Hang in there, dont give up on the 0480 just yet, Mine flogged itself out somewhat and after a few mods it has become quite a useable little grinder. I use mine with my isomac when Im going away, needless to say it does take a little bit of modifying but its worth it in the end.
    there are countless threads in the grinder forum here on coffee snobs.
    by the way welcome to all of the newbys, try "how to fix those dreaded em0480 problems for good"....... it makes interesting reading. The quest for better than good coffee "espresso nirvana" never dies, it spurs you on to that higher experience; press on, you can do it and the little sunbeam 0480 can produce some surprisingly good results as well with a few mods.

    The problem is that sunbeam products are bigger on asthetics rather than build quality. I hope this helps....... Ray.

    Re: SB Emo480 & Em6910 under extraction & grinding

    I got my washer in the post today - it has made the grind a lot finer but alas, still not good enough. Im getting my full 20ml in the cup within 3-4 seconds. Back to the double floor filter for me at the moment, perhaps a trip to Bunnings on the weekend would be quicker than waiting for another washer/spacer.

    Hats off to Sunbeam though, they were helpful on the phone, sent me a new rubber for the machine after I found water leaking out of the back under pressure, sent a spacer and also a rubber sleeve for the grinder. Just took a bit of time and didnt help that I was so excited Christmas Day and its still not fixed.

    Shame your in Perth ;)

    20 ml in 3-4 seconds is so fast it is not funny...

    You need to try the Double PF basket and not the Single..

    But even then with out inspection Grind size Vs freshness is what is causing the probs...

    I do use the double PF basket - thats where the result came from.

    Im back to using the double floored double pf basket! :-)

    Freshness is still ok but not the best, its now 5 weeks out of roasting date. I can feel the grind between my fingers and its still very coarse.

    Im going to attempt some of the suggestions from the post "how to fix those dreaded em0480 problems for good" and see how I go.

    I agree, definitely use the double basket... And make sure that you are tamping hard.

    Also, i recently recommended the sunbean grinder to a friend, but we had heaps of problems with it. It was set to fine. So using any grind setting less than 12 wasnt letting any coffee through and it was pushing ground (well mushed up) coffee back into the hopper.

    We took some washers out, it got better, but still not that great. Then some plastic bits fell out of the spout. My friend took the grinder back to the shop and they gave him a new one -- which worked great!

    Also, have you completely cleaned all of the burrs, etc? Ive found that the sometimes doesnt re-assemble very well if there are heaps of coffee grinds through it.

    If *the dates are correct then the beans should be OK... Supermarket stuff *often has a 6 or 12 month use by and that is crap.. *So 5 weeks from roast should not be excessive.

    That being the case... *Then your grind and Tamp are first cap of the rank - re cause of the problem.

    I just got off the phone to Sunbeam - she asked me how many spacers I now have in my machine and when I answered 2, she said shed send me 2 more. Apparently they should come with 3 from the factory, I had 1 from the factory and 1 additional from Sunbeam. 1 more should get me to factory standard and 1 more in case thats not enough.

    Im tamping with about 75kg of pressure, considering it should be around 10kg I think Im doing all I can with what Ive got at the moment ;-)

    Ive completely cleaned everything as I pulled it apart to add the additional spacer. Fingers crossed for the additional spacers.

    Mine came with one... After 6 months I was sent another.... However I got some SS shim and made up some spacers.. Then I got a brass and a SS washer of the right dia and thin. I had to file / polish them flat as they were punched washers... Thus afer some tweeking I have ONE fat home made washer and a couple of SB ones for later if needed.

    NOTE: Once bedded in I have not seen any further changes.

    Man how many dints in the bench top... Must have large pecks :-?

    Ive completely cleaned everything as I pulled it apart to add the additional spacer. Fingers crossed for the additional spacers.
    In desperation I would cut some hard plastic (thin) and make a washer or two and test while waiting...

    No need to punch a hole... Just cut a slot in wide enough for the shaft and the locating pin..

    Let us know how you go...

    It would do as a test ... Check the thickness as it may well = 2 or 3 of the sunbeam washers... *I was thinking more along the new style security plastic that many products now come in... It is quite hard and not overly thick.. *

    You know the ones you can not open and have to cut with a Stanly knife or a good set of scissors...

    NOTE: Always start off with the setting high as you do not want to grind the burrs together... *

    Mine came with one washer as well and I didnt have any of these problems.
    Maybe its the newer batches of grinders have these issues.

    5 weeks post roast date Id be a bit suspicious.
    I havent ground anything that old for quite some time and then it was only to test the taste at that age.

    Try get some beans that are no more than 7 days old.

    Re: SB Emo480 & Em6910 under extraction & grinding

    Yeah, its my own fault for grinding old beans. I bought a few kilo bags for over the Christmas period - basically us in IT were working over the break and all the local coffee shops were shut. The idea was that I was going to bring in my machine and make coffee for everyone. Then since I had problems with my grinder (which I knew I was getting Christmas day) I didnt bring it in. Ive done pretty well to drink almost 2.5kg of coffee since Christmas all on my own :-)

    I will see what other plastic I can rummage up.

    Re: SB Emo480 & Em6910 under extraction & grinding

    Pure heavenly bliss.

    Thats how I can describe the results.... I went to bunnings and found a spacer with the right outer and inner diameter. The height of it is equivalent to about 3.5 of the standard sunbeam spacers so Ive taken out the sunbeam spacers and replaced them with the one.

    I dialled in at about 10 and could see the difference in grind immediately however there was no resistance and the water poured straight through. I repeated at 5 and had better results but still not great. I tried tamping harder but still no joy so I rubbed some coffee between my fingers and could still feel distinctive small rocks. Visually I could see the gap between the top burr and bottom burrs were very tight, considering I wasnt using sunbeam parts I was extremely cautious about going too far and grinding the burrs together.

    Finally, I dialled in at 1 (really 0, mine seams to go lower than 1) and pulled a ristretto shot and the extraction I got was brilliant, deep rich golden in colour, thick and syrup like texture and extremely sweet to taste. I couldnt be happier!

    Im going to add back one of the sunbeam spacers so Im dialled in at 8-12 for the equivalent of my current 1 grind so that I can adjust down if I need to when the weather/humidity changes, being careful not to go to far and jamming the burrs together. For a minute there I was working my budget so that I could buy a mini mazzer but at the moment, Im very content. Anyone having the same issues should persist!

    Re: SB Emo480 & Em6910 under extraction & grinding

    Now remember... *Different beans will have an impact and when you next pull the grinder apart and then rebuild... *ALWAYS visually check and start your grind off - COURSE...

    I am aware of at least TWO who have for many reasons rebuilt and set to the old setting *(very fine) only to have NASTY outcomes...

    Yes, for the $ the EM0480 is not bad... But unless you have some common sense and mechanical ability (And access to CS) then many will be having problems...

    Not withstanding; others may have a good 0480 but be using OLD store beans and BLAME the grinder...

    A review of the *QA process and Auditing in the manufacture process could add significantly to the product ( small expense for a big impact on market buy in)... *(Thats for you TG)

    So just out of interest.. How many spaces do people generally have in there??

    I have three, and it now SEEMS to be doing the job...

    Well I just have one big one now but 4 would have done the trick.

    If anyone needs a spare spacer let me know, Im willing to part with one for a fellow CSer. I can post faster than sunbeam ;-)
