    Iberital Challenge Glugging up problem

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have had my Iberital (doserless) for a while now and it has been faultless until today. I wound it out to do about 100g of Plunger grind for the shop using a recent bag of Sulawesi Torajah. It got about 1/2 way into it and it started to slow down and not take in any fresh beans. Basically the burrs and the wiper (dispenser star) had become glugged up with ground coffee :-?

    I suppose the question is that common or is it just a lack of cleaning? Anyone else get similar problems with this unit? How often should you drop the top and clean a grinder?

    The bag was only opened 4 days ago and came straight from Brown Bay and it wasnt hot and Humid (I wish living in Southern Vic ::) )

    It may be a foreign object that made it inside

    There’s only one way to find out ? Pull it apart and see

    Hi KK,

    I actually did a full strip and clean 2 days ago. I think the problem may have been using the last of my Stupormarket fresh :o beans. The sweeper under the burrs was fairly well clogged and the discharge chute was nearly 30% closed. Interesting I found around 10-15 whole beans that had found there way into the body of the grinder past the burrs.

    All happy and dialled back in :) DRM will be here early next week so the IC is either getting sold or moving onto Plunger duty.

    cheers

    For what its worth, I have a Rocky Doserless grinder and had this same trouble when I used oily beans. The beans I got were very shiny and kept clogging the grinder up. I managed to dislodge the clogs, and stopped using those particular beans. Since then, it hasnt skipped a beat!

    hey bf
    just yesterday i noticed that when i was grinding for my stovetop, the grinder started becoming audibly lower in sound like it was struggling and slowing down.
    emptied the hopper and had a look down the neck, nothing suspicious.
    left the black plastic section off the top, and noticed that there seems to be a torque effect when i start and stop grinding sometimes. like the black round cylinder with teeth that is adjusted by the worm gear, seemed to move a little much like a car engine under throttle.

    i was wondering if this happens with yours? there doesnt seem to be any play in the burr carrier when i play with it by hand, but am wondering if this torque movement should not be occurring?

    thanks

    aaron

    Hi Aaron,

    I found mine was just clagged up with acumulated fines and oils blocking the outlet which in turn blocked the slingers under the lower burrs which then blocked any ground beans going into the burrs. It finished up with some ground beans above the lower burrs. ::) As this was my first conical grinder put it down to learning :-[

    Since sold to Newbiesnob after a final clean. My new Ascaso seems to share the same upper burr carrier and similar lower one to the IC so I think the lesson here is drop the top every couple of months for a full clean up. Done over an Ale or a nice coffee on the kitchen bench even the big ones only take about 20 minutes (if done regularly).

    Also the upper burr carrier on my big DRMs move a tiny bit and grow mould on the doser vanes if not cleaned :P

    More Cleaning More Better

    I have the same problem on mine... And the issue for me is that even with good beans there appears to be an issue with clumping and it gets worse the finer you ground. In addition the less beans in the hopper then this also causes issues. Thus grinding for a cup or two was an issue.

    Going to the 0.6L click clack lid (K-MART and see post http://coffeesnobs.com.au/YaBB.pl?num=1220170717) has made the difference for me.
