OPERATING
Resetting Default Volumes
To reset the machine to the default 1 CUP
and 2 CUP shot volumes, press and hold
the PROGRAM button until the machine
beeps three times. Release the PROGRAM
button. The machine will return to its
original default volume settings and default
espresso water temperature (see ‘Advanced
Temperature Mode’, page 19).
NOTE
Default settings: 1 CUP shot volume
is approx. 1oz / 30ml. 2 CUP shot
volume is approx. 2oz / 60ml.
Manual Shot Volume
Manually control low pressure
pre-infusion time and shot volume without
re-programming the preset shot volume.
Press and hold the 1 CUP or 2 CUP button.
The extraction will enter low pressure
pre-infusion until the button is released.
When the 1 CUP or 2 CUP button is
released, extraction will continue at full
pressure. Press the 1 CUP or 2 CUP button
again once the desired volume of espresso
has been extracted.
PROGRAM
PRESS & HOLD
NOTE
For optimal fl avor when using a
1 CUP fi lter basket, you should extract
approx. 1oz / 30ml. When using a
2 CUP fi lter basket, you should extract
approx. 2oz / 60ml.
ESPRESSO PRESSURE GAUGE
Low Pressure Pre-Infusion
The gauge needle will be positioned in
the pre-infusion zone at the start of the
extraction indicating the machine is in
low pressure pre-infusion mode.
The low pressure pre-infusion gradually
increases water pressure to gently expand
grinds for an even extraction before
increasing to full pressure.
Ideal Espresso Zone
The gauge needle, when positioned
anywhere within the solid grey zone during
extraction, indicates the espresso has been
extracted at the ideal pressure.
Under Extracted Zone
The gauge needle, when positioned in the
lower zone during extraction, indicates the
espresso has been extracted with
insuffi cient pressure.
This occurs when the water fl ow through
the ground coffee is too fast and results in
an under extracted espresso that is watery
and lacks crema and fl avor.
Causes for under extraction include the grind
being too coarse and/or insuffi cient coffee in
the fi lter basket and/or under tamping.
Over Extracted Zone
The gauge needle, when positioned in the
upper zone during extraction, indicates
the espresso has been extracted with too
much pressure.
This occurs when the water fl ow through the
ground coffee is too slow and results in an
over extracted espresso that is very dark and
bitter with a mottled and uneven crema.
Causes for over extraction include the
grind being too fi ne and/or too much
ground coffee in the fi lter basket and/or
over tamping.
USING THE STEAM/
HOT WATER DIAL
Steam
•
Position the steam wand tip over the
drip tray.
•
Turn the STEAM/HOT WATER dial
to the STEAM position. The STEAM/
HOT WATER light will fl ash to indicate
the machine is heating to create steam.
During this time, condensed water
may purge from the steam wand. This
is normal.
NOTE
When the machine creates steam, a
pumping noise can be heard. This is
the normal operation of the 15 bar
Italian pump.
•
When the STEAM/HOT WATER light
stops fl ashing the steam wand is ready
for use.
•
Before inserting the wand into the milk,
pause the steam by returning the dial
back to the STANDBY position. Then
within 8 seconds, insert the steam wand
tip ¼–¾” (1–2cm) below the surface of
the milk, close to the right hand side
of the jug at the 3 o’clock position and
quickly turn the dial back to the STEAM
position. Pausing the steam avoids the
milk splashing out of the jug (this pause
function lasts for 8 seconds only).
•
Once the milk is at the correct
temperature (140–149°F or 60–65°C)
and the jug is hot to touch, return the
dial to the STANDBY position BEFORE
removing the jug.
