8.1 Cleaning the coffee grinder
1. Clean the attachment area with the brush (C9) (fig. 29).
2. Use the brush to clean the coffee funnel (fig. 30).
Efficient grinding
The burrs are subject to wear over time. This means that with
continuous and regular use, the dial (B4) will need to be turned
toward the higher numbers in order to obtain the perfect dose.
Once a setting of between 30 and 40 has been reached, the extra
grinding range becomes necessary (see section "7. Settings
menu" - "Extra grinding adjustment").
When the quantity of ground coffee becomes less than expect-
ed, contact a service centre to have the burrs replaced. With the
new burrs fitted, adjust the coffee grinder by accessing the set-
tings menu and selecting the first range of the extra grinding
adjustment. Now turn the quantity adjustment dial (B4) to the
Min position and set the quantity as for first-time use (see "The
"perfect dose"").
