Nemox Lux seizing

I had a look and all the teeth seem intact - I then thought maybe the motor brushes were losing contact (perhaps the plastic smell was some arcing), so I cleaned up the commutator and it actually let me grind a litttttle finer. Still seizing getting close to espresso though. Not sure where that leaves me - sunk cost fallacy may be setting in.

Thanks for the help! Will look into the gear to see if its lost its integrity. Cheers LeroyC for the pics and insight!

What noidle said......
It’ll look like this-

With a munted bit on it like this-

Apparently the older domestic grinders had shear pins, but manufacturers have decided nylon gears are a better idea for some reason. It’s a readily available part that is the same in all Lelit/Isomac/Nemox/Imat/Iberital grinders. You have to take the whole grinder apart to get in there so you need to be a little bit handy to do it yourself.

There's a nylon (or some sort of plastic) gear that is driven from the motor to run the burrs. This will have worn down teeth that slip when the grinder is under heavy load (fine grinding). A new gear should solve the issue.
The same gear is used in similar grinders from Isomac and Lelit among a few others I believe.
I think Jetblack Espresso carry parts or it may have been someone else, can't quite remember. You may have to do a bit of hunting online to find the part.

Bad luck re the grinder Darling, from your description (stops grinding, buzzing struggling motor noise, bad plastic smell) I suspect motor damage has already been done.
My suggestion would be to take it to a repairer.

Start up capacitor?
Does the shaft spin smooth by hand?
regardless, dont leave it on trying to spin up while it is jammed, that will likely kill the coils.

Nemox Lux seizing
Hello,
My Nemox Lux keeps seizing (stops grinding, buzzing struggling motor noise, bad plastic smell if I do it too long, only happens when set finer) and I suspected it was the burrs after many years of use.
Upon replacing the burrs (thanks to help in this thread https://coffeesnobs.com.au/grinders/...nemox-lux.html), the issue continues to persist! Although the occasional spout of coffee clumps less and is more even, so the burrs were blunt anyway.
There doesn't seem to be anything clogging, any ideas?
Thanks!Tags: None
