hums but does 

not grind.

clogged.

Grinding is set too 

fi ne.

A foreign object 

is in the grinding 

mechanism.

Remedy

Set grinding fi neness to „coarse“

itself free. Afterwards, return 

the setting to the desired grind-

ing fi neness.

Turn the grinding fi neness set-

trigger the grinding process. 

The grinder will then grind it-

foreign object. Observe the safe-

Insert the plug into the outlet.

Check to determine whether
