    6910 Issue

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

    Im on my 2nd 6910, had it for a year now and am having issues getting it to pull a good shot. my grinder is also a sunbeam EM0450 which is 3 years old. To get even remotely close to a good extraction I have to set my grinder to the finest setting so much so that it is clogging, Im tamping the right way, doing the whole 5cent piece thing and wham shot blows out super fast and blonds real quick.

    I noticed when I got my 2nd machine that the group head had to be locked further to get it to seal properly, now it seems need be to locked even further. My rubber seal is still in good condition and not torn or anything so im stumped. Has anyone had the same issue? or simular/ any ideas? Im starting to get over the 6910 my steam wand has no grunt and my last machines steam pump shit itself! :(

    Any help would be greatly appreciated.

    Do a search on teh grinder as it could need a washer... Added.. Lots on CS about it..

    Other than that, it just sounds like Beans from what you have said..... Sorry... Hard to TS when across that ditch...

    A: What is ya sweet spot and what are you running at with beans...

    B: You say local roaster... How old / when were they roasted ?

    The group head is probably worn.

    Do a search and youll see lots of info regarding that.

    Re: 6910 Issue

    Cheers.

    The beans I have been buying are around 2-4 days after roasting so pretty fresh.

    My first thoughts were the grinder as its the oldest part, should you get down below 5 on the sunbeam grinders for expresso? I will look for a the washer on CS.

    Sweat Spot: If i did it correctly ( chuck in the cleaning puck flick it on and see where it sits on the guage?) Mine sits about halfway on the dark brown.

    Cheers for ya help.

    hi Poo,

    my advice would be to get a better grinder. My machine use to leak around the head sometimes when i pulled a shot because i was using a cheap grinder. Since i got a better proper burr grinder that issue has dissappered. Also the portafilter should lock facing straight towards you ( 6 o clock position). Any further and it will start to damage you collar.

    So the conclusion is try your best to get a commercial stlye grinder and all the other problems should be fixed. :)

    Keep us posted. :D

    A 0450 is an OK grinder for use with a 6910.
    Yes a better grinder will make less mess, make less noise and grind more consistently, but thats NOT whats causing the problem.

    As I said before - "The group head is probably worn".

    I fully suport TG comments... Course or fine is not the issue... If dirty and bits of coffee fines in and around the seal / split seal or worn collar....

    The better the grinder the better control over ya grinds... But that will not cause a leak... The leak is a symptom of a mechanical or user problem..

    Yea the leak might be due the reason mentioned above. But the em 6910 is NOT a commercial machine. Yea it looks tough and makes great coffee. I am a barista and i use a commerical machine at work everyday so i know how it feels.

    The 0450 is probably ok. But after using my sunbeam em6910 i have realised the limitations of an appliance. For the price of a 0450 grinder you could probably find a second hand commercial type grinder ( that wont break down or need a washer or other mods) for a little bit more money and it will probably last 2 or 3 times longer than the 0450 ever will. :)

    Re: 6910 Issue

    anu I agree that a 2nd hand commercial grinder can be picked up cheap (I got a conical Gino Rossi for under $300) but poo already has a grinder that is adequate, so recommending spending more money is not going to fix the current problem.

    I have owned a 0450 (recently sold) and have been using a 6910 at work for the last few years.
    I also am a qualified barista and although my last stint behind a commercial machine was a little over 6 months ago, I still remember the difference between it and the Sunbeam.

    poo you need someone who knows to check the group head for wear.

    As for the steam, has it always been poor on this unit or gotten worse than before?

    Re: 6910 Issue

    yea definantly sounds like your grind or beans.

    Your sunbeam em6910 has a common problem with handle slowly coming around further, what you will evenually need is a new "collar" , we replace these alot unfortunantly. A quick fix at the start is a packer for the seal but this is a bandait fix. Thanks
