Dear Fellow Coffee Addicts,
I’ve had this M2M C83 Macap grinder for 4 years now. Really love it. It has started seizing with grinds collecting in the recess below the lower conical burr and stopping the burrs spinning. No grinds coming out of the machine. I have carefully cleaned it and tried again with coarse and fine settings with the same result (please see attached image).
Was working fine until I tried to make more coarse grounds to try some cold brew coffee.
I had the same problem some years ago and found that a specific brand of beans would work. No beans working now and I am withdrawing from caffeine 😱
Would really appreciate any advice you could give me.
Thanks in advance.

Before you completely remove it, have you tried running something like a pipe cleaner (or even a piece of wire) through the chute starting from the grind chamber side.
