My Iberital grinder has come to an extremely sudden, screeching end. Id barely begun grinding some Columbians from last months batch when it made a high - pitched whining noise and came to a dead stop.
Its the sort of noise that tells you theres more than a stubborn hard- SO bean at play in the burrs.
On inspection, there was a square-looking thing wedged in the burrs. I plucked it out:
A small nut.
Not the edible or idiotic variety, but the metal ones which screw onto the ends of bolts. Not a bright metal colour, but the same roast grade as the surrounding beans.
Where it heralds from....? Perhaps deep in the plantations of Colombia.
But back the grinder. No noticeable broken or mangled teeth, so put back the hopper and beans, and tried again.
At first, nothing, then a free-spinning motor doing no work .
Dismantled the grinder, removed the top mounting plate, removed the motor from it....
To cut a long story short, a large nylon reduction gear has three missing teeth, and trying to separate it from its shaft broke the shaft.
I really hate paying for someone elses carelessness... Nuts indeed.
