HOLDERS
Check the wear and tear on the lters, check the edge of the lters for damage and check
for any coffee grounds in the cup and replace lters and/or lter holders if necessary.

cated by the presence of too much dust in the grind. It is advisable to have a technician
replace the at burrs every 400/500kg of coffee or every 800/900kg of coffee in the case
of conical burrs.
