BREW GROUP MAINTENANCE
All Saeco fully automatic machines are equipped with a removable brew group.
This patented technology allows you to thoroughly clean the parts of the brew
group in contact with coffee and the entire brewing area inside the machine.
This brew group maintenance kit comes with 2 different O-rings, as shown on the
previous page (small and large). Before starting the instructions on the following
pages, overturn the brew group, and choose the correct O-ring size based on the
images below. (The following images show the fi lter screen with the upper part
of the brew group removed. This is for demonstration purposes only; the upper
part of the brew group should never be removed.)
