Has your Breville or Sage Coffee Machine or Grinder stopped grinding? – it’s probably making a clunking or whizzing noise and not grinding anything? It is possible a cog within the grinder mechanism has been stripped. This is usually caused my an object other than a coffee bean going through the grinder, usually a stem or coffee bean looking stone.
The good news is sometime this issue can be resolved without replacing the grinder. I said sometimes, here is the methodology, perhaps you won’t need to purchase a new grinder. I will use pictures and as always be as graphic as I can.

  1. Remove the cover plate attached to the motor and expose the scene below. You then need to remove the cog I m pointing at by unbolting it. It’s a reverse thread and you will need to hold the inner burr to undo it. When is it’s removed Springs and ball bearings will fall out. Don’t panic.

The springs and ball bearings have dropped out. They are easy to reinstall according to me.
The springs poke in the holes with the ball bearings on top.

2. Now remove the drive cog, this is the one that is stripped and I intend to replace it. Yes I will have spares for sale.

This is the damaged cog.
The damaged cog showing the area of missing death. Not a great pic but the teeth are gone.

3. Now it’s time to reassemble the grinder with the new cog in place. You have to be careful getting the springs and ball-bearings back in place, but it can be done, in one easy movement.

The cog loaded with the springs and washers ready for the one easy movement, don’t forget the plate and to put it back in the right way.
Ok just need to put back the nut on the large cog and the washer on the small one. The large cog will tighten onto the springs. It’s all so beautiful.
Done, now its time to put the plate and motor back on.
Thats all folks – no I haven’t got bits left over, I have 2 grinders in play. Yep I intend to test it.
