Operation - La Marzocco GS/3 Owner's Manual

1. Installing the Portafilters.
Install the portafilter by inserting it into
the group head and rotate the handle
from left to right. Once the portafilter
is inserted properly, you can press
one of the brewing buttons on the
keypad (AV model) or move the paddle
handle from right to left (MP Model)
to start the flow of water through the
Figure 8 - Portafilter
portafilter. Please refer to the Software
Programming Manual for a description
of the functions of the keypad.
It is important that the portafilter is at
operating temperature prior to filling
with coffee. Allow hot water to pass
through the empty portafilter for a few
seconds before the brewing process to
pre-heat the portafilter.

5. Operation

Note: It is important to leave the
portafilter installed in the espresso
machine when not in use. The portafilter
must remain heated for the brewing
process to function correctly.
2. Brewing Coffee. It is now possible to
remove the portafilter to make a coffee
beverage. Place some ground coffee in
the portafilter basket using the single
or double basket. Press down on the
ground coffee with the supplied tamper
and install the portafilter on the GS/3. On
AV model press a brew button to begin
the brewing process, or move the paddle
handle from right to left to begin brewing
on MP model (see Fig.2).
NOTE: Some users believe it is important
to allow water to pass through the
the group head prior to installing the
portafilter to flush any remaining coffee
oils and particles from the group head.
Some also flush just after brewing for
the same reason. Please experiment to
make the best possible procedure for
your coffee. There are many techniques
for brewing espresso. You can find
instructions for many techniques on
websites, blogs and forums. Some are
even monitored by professional baristas
around the world.
