Generally:
 Is the ground coffee very coarse even on the finest setting or is it not homogeneous? Then the grinding stones are worn out and should be replaced.
 Old grinding stones often no longer deliver the required amount of coffee to the brewing unit.

 Advantages:
 - Tried and tested grinding stones for Miele fully automatic machines, the CM 5 / CM 6 / CM7 series
 -Uncoated grinding stones are sharper, small spots of rust are not a quality defect!

 Settings:
 -Install new grinding stones. Close the grinder completely and unscrew it 11 clicks.

 When should they be changed?
 -After about 6 to 10 thousand references
 -If the coffee grounds are too coarse
 -The amount of coffee is not sufficient

 Additional Information:
 -Grindstones are generally made of steel, which is then hardened to make the grindstones wear-resistant. Grinding stones made of stainless steel become blunt much faster and are not the right material for a grinder.
 -Other suppliers offer a coating to prevent rust formation during storage. Coatings always settle on the edges and dull them. The manufacturer's grinding stones are also not coated.
 -The grinding stones grind about 10-20% more than the original grinding stones, so you can reduce the grinding quantity / strength in the settings.

 A notice:
 -We guarantee 100% compatibility - This is not an original Miele spare part.
