Key Features - La Marzocco GS/3 Owner's Manual

1. Controlling the Brew Process Using
Volumetric Programming.
This espresso machine allows the
volumetric programming of each of the
first 4 buttons on each group (numbered
left to right). Please consult the Software
Programming Manual for
instructions.
2. Hot Water dispensing. Hot water may
be dispensed from the Hot Water Wand
on the right side of the machine. This is
accomplished by pressing the hot water
button (Fig.9). The amount of water
dispensed can be programmed via the
digital display. Please consult Software
Programming Manual for programming
instructions. The temperature of the hot
water may be adjusted slightly via the
Hot Water Adjusting Knob. This adjusting
knob is hidden under the right side panel
assembly. The knob protrudes slightly
form the bottom of the side panel. To
find this knob, look at the bottom edge
of the right side panel.
The knob may be turned by sliding a
finger under the side panel from front to
rear (to decrease temperature) or from
rear to front (to increase temperature).
3. Quick Keys.
The GS/3 has 4 Quick Keys to allow
the user to gain quick and easy access
to important parameters that may be
changed frequently. Please see the

5. General Notes for Coffee Preparation.
The portafilters must remain heated
since they are at the lowest position of
the group itself, and they are partially
isolated from the same due to the
rubber gasket between them. This can be
accomplished by leaving the portafilters
installed in the machine when not in
use. The portafilters may also be actively
heated by activating one of the brew
buttons to flush hot water through the
portafilter then turning off the water
flow.
6. Coffee grind.
The size of the coffee granules is
extremely important in preparing a good
cup of coffee, along with the type of
coffee blend used. The ideal grind can
be determined by making various coffees
using the amount of ground coffee that
you would normally use for each cup (we
recommend at least 6g). The best grind
is that which allows coffee to flow out
from the portafilter spouts neither too
slowly, drop by drop, nor too quickly. A
general rule is that a double dose should
dispense approximately 60mL / 2 fluid oz.
of espresso in approximately 25 seconds.
This time may be adjusted by varing the
coarseness of the grind.
