The degree of grinding is too coarse.
Manually set the degree of grinding to a finer degree in increments:
- Open the coffee machine door. 
- CM xxxx: 
 
- CVA 7xxx: Remove the water container. The slide control for adjusting the degree of grinding is located on the top left behind the water container. 
 
- CVA 5xxx and 6xxx: 
 
- Push the slide control exactly 1 setting to the left (for finer grinding). 
- Close the appliance door. 
- Make one cup of coffee. 
Adjust the degree of grinding again by 1 setting, if required.
