Hello dear community!

I recently opened my Siemens EQ9 S300 and noticed that there is clear abrasion or black dust to the left of the grinder on the motor. Looks like coal dust. I wanted to ask if this is normal after about 6,000 uses or if the motor is about to stop ?

Many thanks for your help.

Greetings Peter
