Iberital grinder stopped working, any suggestions?
So i purchased my Iberital Challenge grinder recently from another forum coffee snob.
Now it has randomly stopped working. Fine one morning, won't make a peep the next. This is now the second time this has happened.
I've turned it on and off again, removed then replaced the beans, but I'm no grinder mechanic, hence this post.
Any suggestions/obvious fixes to get this grinder going again - before I seek help that costs $$$ - would be most welcome.
Faulty hopper switch?
Faulty power switch?
Will be something easy, just be careful, 240v bites
Make it coarser, may be the top blades and the bottom one are getting stuck
I can vouch for that. Was changing the blades on mine and had to give it a few goes. On one attempt forgot to turn it off, dropped a screw onto the transformer, went in there with my screwdriver to retrieve it and felt the full force. My wife was not impressed!

The machine workings can be rotated via a spanner at the cone and the fault sometimes happens midstream during grinding so it doesn't seem to be a mechanical problem.
On numerous occasions after I've checked inside (brushes for length, compression and seating, plus the continuity of switches, connectors and circuitry) the machine had worked again when reassembled.
I then found that rather than disassembling it each time, a sharp tap on the left hand side made it work again.
Unfortunately right now however, successive tapping and any degree of impact I'm lucky if the machine works for 5 to 10 seconds before stopping :-(
I took it to a coffee machine place who said it was the brushes but these weren't available as a spare part and therefore it would require a complete new motor for $200 plus fitting.
I really like the grinder and it was a gift from a loved one so I am not keen to throw it out just yet.
Any suggestions please?
Humbug! Brushes are always available (assuming it is the brushes). Where are you located? I can recommend a good guy in Sydney.

Brushes should be a very simple and easy find. Sounded to me like a faulty microswitch if its not the brushes
