Using The Steam/Hot Water Dial; Auto Purge; Over Extracted Zone; Steam - Breville Barista Express Instruction Book

This occurs when the water flow through the
ground coffee is too fast and results in an
under extracted espresso that is watery and
lacks crema and flavor.
Causes for under extraction include the grind
being too coarse and/or insufficient coffee in
the filter 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 flow 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 fine and/or too much ground coffee
in the filter 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 flash 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 opera-
tion of the 15 bar Italian pump.

• When the STEAM/HOT WATER light stops
flashing 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.
• For more tips on milk texturing, refer to
'Texturing Milk', page 20.
NOTE
After 5 minutes of continuous steaming, the
machine will automatically disable the steam
function. The STEAM/HOT WATER light will
flash. When this occurs return the dial to the
STANDBY position.
Hot Water
• Turn the STEAM/HOT WATER dial to
the HOT WATER position. The STEAM/
HOT WATER light will flash to indicate the
machine is heating to create hot water.
• When the STEAM/HOT WATER light stops
flashing the hot water is up to temperature.
Hot water will pour from the hot water outlet
and can be used for making Americanos and
pre-heating cups.
• To stop the hot water, return the dial to the
STANDBY position.

AUTO PURGE

Immediately after the espresso, hot water and
steam functions, the machine will purge water
into the drip tray. This ensures the thermocoil
is at the optimal temperature.
