    Breville Barista Express 870XL Extraction issue.

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    HI everyone, of course I'm new to this My current situation is this. I'm using inexpensive store bought beans to practice with at first. I've had the machine only a couple days. My grind size (Set to 5)m single wall filter and dose/tamping seems to be good (good using razor) because it gets me to the high side of the good pressure zone between 12:00 and 1:30 position pretty consistently. and I'm getting just slightly under 1 ounce for a single shot. What is frustrating me is the 18 sec extraction time (from the time I press the button). I can't figure out how to get the 25-30 second time without going into the 1.5 to 2 ounce range. Everything I have read has been about getting the grind and dose/tamp right in order to get the proper extraction pressure. I assumed once I got that the rest would fall into place. NOT! Any suggestions?

    Thanks

    UPDATE: One quick update, I just ran the process to program the 1 shot button. The pressure was up to just past the 12 o'clock position and I programmed to run for 25 seconds (starting when I pushed the button) and at the end of 25 seconds I had 2 ounces (measured in a gratuated beaker) on the single shot setting. Any idea what I'm missing?

    Hi Rob, beans should be fresh, preferably within two to four weeks of the roast date. Most supermarket coffee is well beyond this window. Grab some fresh beans from your local caffeine dealer or order online, and give that a go. Good luck.

    Your issue is the stale supermarket beans.

    I understand your idea behind using cheap beans to practice your technique, but the issue is that you really are wasting time as the end result will never be correct without proper fresh beans.

    I've had my own issue

    Got the 870XL a couple months ago and it had been absolutely perfect. Then out of the blue this morning, I went to make an espresso and the pressure gauge barely moved at all and I got a super under-extracted shot out. I tried 3 more times and the same exact thing happened. I purged the head and everything and still super sour gross non-espresso with absolutely no pressure. I'm not happy about how quickly this failed, but should I just return it given it's probably still under warranty? So sad.

    Did you grind finer? Are your beans fresh? Which basket are you using, double or single? Forget about the single basket, it's inconsistent and more difficult to get right. Weigh your beans 17 grams in the double and see how you go.

    Suggest you run the cleaning cycle.

    Didn't change a thing from what I had been doing and nope, I pretty much always go with the double. There was one time recently I did a single and the puck stuck to the group head, which I found odd but the shot itself was fine. I cleaned and descaled (twice...that's a lot of vinegar!) yesterday but absolutely no change. Guessing I need to return.

    Let us know how you get on. I've had mine for 4+ years and it's still going strong.

    Is it dumping water into the tray during the shot? Id say the solenoid is leaking and needs its clean

    Looks very similar to what happened to me after 3 years. Should not be happening after 3 months. I think the XL means it is a USA machine. Warranty in Oz is 12 months and you have access to the Australian Consumer Law. So suggest you make a claim if you can, otherwise clean with Evo. When my machine stopped I cleaned 3 times with the manufacturer's tablets which failed. I then ordered in Evo powder and on the first go flushed some dirty muck out and it was working again but still had a rattling shot button, but not as bad. Hope that helps.
