It's probably the switch contacts, that got a little dirt or dust between
them. Or, relay contacts if it has a latching relay to control the motor
power. (likely so if it has a doser with a full-limit switch)

Take your pick- all easy to clean- the on-off switch, the full-limit switch
if it has a doser, or the latching control relay. Where would you get dust
particles in a grinder??

With the machine disconnected from the power, vacuum and brush out all the
electrical parts. Use a computer keyboard vacuum cleaner adapter while you
also flip the switch and manually depress the relay armature. If the motor
has brushes, they might have been right at the wear limit the last time you
ran it.

If it has worn brushes don't play around, replace them now. Save the motor
commutator/ armature, if you can even find a replacement armature.

Let the fun begin.
