    More SB 6910 Extraction Issues

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

    Im having extraction issues with my EM6910. Using the single floor basket the shot is under-extracted. The water literally runs through the basket. I dont have a grinder, our coffee supplier grinds to spec for the machine. The current grind is 1, which is usually perfect, but over the last few weeks Ive only been able to use the dual floor basket, which is a poor substitute.

    Ive also run a clean, and am about to do a full descale.

    Help please. :-/

    There lies the issue,

    Your coffee will be stale and the chances of your local getting it right for your machine are probably 1/100.

    Time to go shopping for a grinder and coffee which you knwo was roasted within a couple of weeks of purchase.

    Hi Bra-Barista

    Coffee, once ground, has a fresh life of about 3 minutes. Sounds to me as though what is happening is that you are getting your coffee pre-ground, its drying out (the oils) and going stale, and theres no resistance for the water to get through.

    Solution: Save as much as you can, as quickly as you can, and buy yourself a decent grinder (decent, as in burr grinder, not whirly blade one). The generally accepted entry level grinder is a Sunbeam EM0450 or EM0480, or work your way up from there if you have the extra money, and buy one from a site sponsor over on the left hand side.

    Id suggest that, until you starting grinding your beans on demand, you wont get a good shot of coffee.

    Cheers
    Di

    This suggests you previously werent having a problem.
    Whats changed?

    A clean and descale will not fix the problem.

    As Di and 2mcm said it appears from your description that the coffee is stale.

    Does your coffee supplier tell you the roast date of the coffee?

    I fell victim to this situation before investing in a grinder. *I had no idea of how quickly coffee went stale. *I used to buy 500gs ground coffee just for myself and only having one or two coffees a day. *::)

    I thought crema was some magical thing that you needed 10 grand of Italian equipment to produce! *(using a $100 breville at that time)

    The main reason Im posting is to reinforce the statement buy the best grinder you can afford.

    I bought the cheapest burr grinder I could find at the time, within a month was kicking myself for not doing some research and buying something better.

    For example my saeco mac-001, is set to its second finest setting (0.5). *If turned to the finest setting, it makes a dentist drills noise which I imagine is the burrs interfering! * >:( *Luckily Ive only flicked it that far for a brief moment and am fairly sure of minimal burr damage.

    So in effect Im at the finest setting with very little adjustment. *Ill be upgrading when my finances permit.
