Open the device and follows all steps, it's easy. You can use the old thermal paste, there ist enough of it in thermosensor, just spread it using a screwdriver. Good luck.

When installing, insert the big gear so that the zero mark points to the axis of the other gear. I think it´s similar for the Minuto.

The “official” way is not to disengage the glasspanel. As you can see in step 7 the panel is held by two locks. It´s really difficult, but you can open them using a very long screwdriver. Lay the device on one side, there are openings on the bottom in which you can insert the scrwedriver and hopefully find the two locks…

And: be shure that the beans are dry! Wet beans bake together, and the grinder will not work anymore.

I could fix it easily by reinserting the helix as I described above! Be sure the taps fit in the groove of the drive shaft.

This morning I replaced the grindstones in a J5 and - had the same issue. Fill beans error. Using the toilet paper tube I could see the grinder spinning, but nearly no coffee grounds falling into the brewing unit. So I took off the helix and inserted it again. I'm sure, it was misaligned. There ist a groove in the drive shaft and two taps in the lower end of the helix have to fit in! If this ist not the case, the distance between both grindstones is not correct.
