    Grinder troubles again - doesnt like fresh coffee!

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have a lelit PL53 which is around a year old.

    It did a great job to begin with using Lavazza beans. (Every now and then Woolies sells them at half price, $15/kg)

    After about 4 months I purchased some pricier fresh roasted beans.

    Shortly after the grinder stopped grinding. Pulling it apart I discovered it was all blocked up with grinds. I replaced the plastic sweeper arm (cracked housing) and another plastic part in the same area.

    One thing I noticed is that nothing drives the sweeper arm directly - it just works off friction from the turning burr?

    Anyway I put it back together and it worked fine on the Lavazza beans.

    I asked the supplier what he recommended to stop it happening again, and his response was to bang it out upside down every week or so. Which Ive done.

    I started roasting my own recently, and straight away I noticed that they dont grind as well. Totally different note coming through the grinder. Yesterday, after nearly 1kg, its stopped again.

    Anyone have any ideas what Im doing wrong? Is it possible to own a grinder without pulling it apart regularly to do maintenance? Because at this stage of my life Im struggling to find time to fix broken things let alone do preventative maintenance on small appliances. I just want them to work.

    Re: Grinder troubles again - doesnt like fresh coffee!

    Ive been having similar problems with my fresh roasted (< 1 week) Brazilian yellow bourbon beans.
    Things get clogged up and the burrs keep spinning but nothing comes out. A little Percussive maintenance and things move again for a short while.
    I havent really had this problem before with other beans regardless of freshness.
    I should probably try to let them age for a week and see if that helps, but I havent got around to roasting that far ahead of myself yet :)

    Your supplier is an egg head* :D :D :D and one day you are going to damage your grinder (probably drop it). Use a vacuum cleaner to simply suck it out occasionally. That wont damage anything.

    Re your "...Yesterday, after nearly 1kg, its stopped again...."

    This is designed as nothing more than a short burst "on demand" grinder and putting 1 kilo through in one sitting, which it is not designed to do, will most probably cause the effect you are getting.

    Yes. No one should have to pull it apart at all unless there is a breakdown.


    Using your "L" coffee in the first instance could be the cause of the problem. It is likely to require a finer setting than if you were to use a fresh product all the time. Consequently when you load up with a fresh product you should probably wind out the adjuster a short way to compensate before starting the grinder, or it could choke straight up on the denser product.

    In addition, if then you found you wound it out too far and it is a bit coarse and needs to be slightly finer again, only wind it back while the motor is running or that could cause a jam.

    This is pretty standard grinder management and I hope that helps.

    Taco:
    grind too fine for the Brazilian? If so as above.

    Are your Brazilian beans physically larger than other coffees you use?* If so they may not be drawing down through the inlet throat esp if there is already a restriction in the throat usually pieces of broken beans etc. Use a vacuum cleaner to suck out or simply brush out the inlet throat occasionally and see if that helps.

    Hi Fresh, good idea with the vacuum, Ill try that.

    Sorry I probably didnt write it clearly, what I meant was 1kg total of my own roasted beans (ethiopian gambella from here). Ground over a few weeks or so.

    I have managed to get it up an running again by giving it a good clean out up the chute with some flexi wire.

    It just seems funny, fresher beans behave very differently. Must be a different consistency, brittleness, oil content or something?

    I have wound the grind back a bit too, as it was very very fine. I had set it by choking my Butterfly, then backing it off till it was pouring at a reasonable speed again.

    I have roasted another 600g this morning, well see how that runs through now!

    Re: Grinder troubles again - doesnt like fresh coffee!

    A bit late but Ill jump in, Ive had a PL53 for a bit under two years - its never missed a beat or had any issues even remotely like this. Ive always used fresh commercially or self roasted beans on it.

    Two things which come to mind;
    - do you adjust the grind when the motor is off?
    - I find the best way to keep the grind shoot clear is once finished grinding lift up the grinder and tilt it forward 30-40 degrees and lightly give it a few taps on the bench - if you aim well you can get these ground in the porta filter too!!

    Im not sure if this would cause a burr alignment issues in the long term but I havent had any problems

    Cheers
    Matt

    Not late at all, good to hear from another owner. I like the look of the PL53 (as opposed to a Rocky, say), matches the old school style of the butterfly nicely, and the grind is very even and as fine as you like. But I havent been overly satisfied with reliability so far. Nice to hear someones had a different experience.

    I only tighten the grind with the motor running, but loosen it with it off.

    Ill definitely try the tip forward method and see if that helps.

    Fresh beans are **NOTHING** like stale beans. They grind differently, smell differently and make a completely different beverage.

    ps--it sounds as though you are on the right track--starting the adjustment process from scratch.

    Another thing I did was permanently remove that lame screw for holding the chute on. I found wedging a toothpick in there instead made it a lot easier to take off and clean which I probably did every week or so.. it stays pretty clean from tapping on the bench though!

    Anyway hope it improves for you :)

    Thats a great idea, that screw is nothing but trouble. On mine the screw is actually loose inside the plastic ridged bit (finger grip), so I have to grip it hard with pliers to turn the metal screw inside. PITA. The chute wedges in tight anyway, its not doing anything. I think mines gone tomorrow too!

    Now that the beans have aged a little Im not having the same problem.
