Tips

PRE-HEATING
Heating your cup or glass
A warm cup will help maintain the coffee's
optimal temperature. Pre-heat your cup by
rinsing with hot water from the hot water outlet
and place on the cup warming tray.
Heating the portafilter and filter basket
A cold portafilter and filter basket can
reduce the extraction temperature enough to
significantly affect the quality of your espresso.
Always ensure the portafilter and filter basket
are pre-heated with hot water from the hot
water outlet before initial use.
NOTE
Always wipe the filter basket and portafilter dry
before dosing with ground coffee as moisture
can encourage 'channeling' where water by-
passes the ground coffee during extraction.
THE GRIND
When grinding coffee beans for espresso, the
grind size should be fine but not too fine. The
grind size will affect the rate at which the water
flows through the ground coffee in the filter
basket and the taste of the espresso.
NOTE
When switching between the 1 Cup & 2 Cup
Filter Baskets, you may need to adjust the
Grind Size to fine tune your extraction.
If the grind is too fine (looks like powder and
feels like flour when rubbed between fingers),
the water will not flow through the coffee even
when under pressure. The resulting espresso
will be OVER-EXTRACTED, dark in color and
bitter in flavor.
26
If the grind is too coarse the water will
flow through the ground coffee in the filter
basket too quickly. The resulting espresso
will be UNDER-EXTRACTED, lacking in
color and flavor.
AUTOMATIC GRINDING,
DOSING & TAMPING
• Ensure hopper is filled with fresh coffee
beans. We recommend quality 100% Arabica
beans with a 'Roasted On' date stamped on
the bag, not a 'Best Before' or 'Use By' date.
Coffee beans are best consumed between
5–20 days after the 'Roasted On' date.
Stale coffee may pour too quickly from the
portafilter spouts and taste bitter and watery.
Never put pre-ground coffee in the hopper.
• Align portafilter handle with the INSERT
position on the grind outlet. Lift to insert
portafilter into the grind outlet and rotate to
the center position.

GRIND OUTLET
• To start the auto grind, dose & tamp function,
rotate the portafilter to the right then gently
guide back to the center position. Grinding
will commence.
