Features Assembly
BEFORE FIRST USE
Unpack all parts and accessories before
removing and safely discarding all packaging
material and promotional labels. Ensure the
power cord is unplugged from the power outlet.
Wipe the exterior stainless steel housing with
a soft, damp cloth. Wash the lid, brew basket,
cone filter insert, mesh basket filter, and carafe
in warm, soapy water and a soft cloth. Do not
use abrasive cleansers, pads or cloths which can
scratch the surface. Rinse and dry thoroughly.
Press carafe drip stop ensuring it can freely

Operation
BREWING A CARAFE
Ensure the brew basket is clean and the drip
stop seal in the bottom of the basket is clean
and free of coffee particles.
1. Select the correct basket & filter for the
amount of coffee you’re making. When
brewing between 2 and 8 cups, we
recommend you use the Cone shaped filter
basket insert with paper filter (Cone paper
filter is not included). When brewing more
than 8 cups, use mesh basket filter or flat
bottom brew basket with large paper filter.

type, rotate the SELECT dial to Settings &
press the dial. Rotate the SELECT dial to the
basket type, press the SELECT dial to set.
3. Fill the water tank with fresh cold water up
to the MAX marking on the water tank.
WATER HARDNESS SETTING &
FLUSHING
1. Ensure that the empty coffee basket and
empty carafe (with assembled lid) are
inserted into the machine.
2. Fill the water tank with fresh cold water to
the MAX mark on the water tank. Plug into
power outlet.
3. When first turned on, the machine will
show 'SEt HArdnESS' on LCD, asking you
water hardness level. Press SELECT dial
once. Dip the water hardness test strip into
the filled water tank for 1 second, remove
and wait for 1 minute to reveal the result.
Rotate SELECT dial and press the dial to
select the level according to the number
of dots shown on the strip. To reset water
hardness, please refer to FACTORY RESET
(page 18).
4. The machine will show ‘FLUSH Unit’
on LCD. Press SELECT dial once. The
machine will dispense all the water from
the tank, through the system & into the
empty carafe. After flushing, empty the
basket and carafe.

11
NOTE
Coffee with superior taste & clarity will come
from using a paper filter.
NOTE
The mesh basket filter will allow some fine
coffee grounds to brew into the coffee. This
will appear as sediment in the cup or carafe.
This is normal. Only use the mesh basket filter
provided as others may cause the machine to
overflow.
7. Lock the carafe lid and place the carafe
under the drip stop outlet.

CAUTION
The carafe MUST be in place before you brew
with water level higher than ‘SINGLE CUP’
line. Otherwise the coffee basket will overflow.
NOTE
Always ensure your carafe is clean and empty
before brewing. Residual coffee will affect the
taste and liquid in the carafe will cause it to
overflow.
NOTE
Always ensure your carafe is EMPTY before
brewing to prevent overflow.
NOTE
This machine will brew all the water in the tank.
Ensure the tank does not contain an excess
amount of water.
4. For the very best tasting coffee, we
recommend using freshly roasted whole
bean coffee and grind with a burr grinder
directly before you brew. The grind should
be medium/coarse, never use coffee ground
for espresso as your coffee basket may
overflow.
5. Grind enough coffee beans for the volume
you’re making. For a full 1.8L carafe, we
recommend 99g of coffee, approximately
12 level Breville measuring scoops.
Roughly 1 scoop for every 150ml.
Refer coffee/water ratio chart on page 14.
6. Insert the correct filter paper, cone or flat
bottom, or mesh basket, into the brew
basket, then, add your ground coffee. Insert
the brew basket into the machine.
NOTE
Never use both mesh basket filter and paper
filter at the same time.

• Bloom Time: Coffee bloom occurs
when hot water hits the ground coffee.
This setting allows you to adjust how long
the bloom time lasts. We recommend
30-60 seconds. During this time
the brewing cycle pauses to allow
coffee to naturally bloom. See ‘TIPS’
for more about Bloom Time.
• Brewing Temp: You can adjust the
temperature of the brew water being
delivered to the ground coffee to suit
your favorite coffee. See “TIPS” for more
about setting brew water temperature.
• Flow Rate: You can adjust brewing time
to control contact time by adjusting the
water delivery speed. Choose between
Slow, Medium, and Fast (default).
• Pour Over: If you are using the Pour
Over Adapter, this must be turned on.
• OVER ICE: This is to make stronger coffee
for ice coffee.
• Fill the water tank with the amount of
water you want to brew up to 600ml
line and start brewing. After brewing,
pour over ice. See ‘TIPS’ for details.
• COLD BREW: Cold Brew coffee is brewed
differently to traditional coffee. It uses cold,
not hot water. Your brewer uses the “Full
Immersion” method of brewing cold brew
which steeps the water and coffee together
over an extended duration – typically
between 4 - 14 hours. This method creates an
intense smooth coffee with little bitterness.
Brew ratios are also different, and much
higher than normal. Breville recommends
a brew ratio 2-3 times higher than average,
approximately 3 Breville scoops to every
150ml of water.
• See ‘TIPS’ for step-by-step guide
of brewing Cold Brew.
• Brew time is adjustable.
NOTE
OVER ICE mode and COLD BREW mode
will be disabled if there is more than 600ml
of water in the tank.
8. Rotate the SELECT dial to the desired
mode. Press the START|CANCEL button.
The machine will display the progress:
• The machine will remind you to insert
either cup or carafe where applicable
• Heating: the heating system is being
pre-heated to the optimal temperature
• Blooming: the bloom phase of
preparation is in progress
• Brewing: brew water at the correct/
selected temperature is being
delivered to the ground coffee
9. When your coffee is ready, the machine will
beep 3 times. The machine will display the
“Time since brewed”.
NOTE
A small amount of water remains in the
tank after brewing. This is part of the normal
operation.
NOTE
Never fill the water tank once the coffee
machine has started a brewing cycle.
BREW MODES
• FAST: This mode is to deliver the fastest
brewed coffee. This coffee machine is one
of the fastest 12 cup (1.8L) brewers.
• GOLD (recommended): This mode meets the
SCA (Specialty Coffee Association)'s rigorous
technical requirements using the cone filter
basket.
• STRONG: This brewing mode delivers a
stronger tasting coffee.
• MY BREW: Allows you to customize every
brew setting.

13
NOTE
DO NOT fill the water tank more than
SINGLE CUP line or the volume of the cup
used to receive the coffee. It will overflow as
the machine brews until the water tank
becomes empty.
2. Place your empty cup underneath the
brew basket outlet.
3. We recommend using cone filter basket
insert for single cups. It ensures proper
contact between the brew water and the
ground coffee.
4. To change the basket type, rotate the
SELECT dial to Settings and press to enter
the Settings mode and select "Basket Type".
5. Rotate the dial to select “Cone”, and press
dial to select. “Cone” will be displayed on
the LCD.
6. Insert the Cone filter basket into the brew
basket. Use the alignment marks as a guide.
7. Place a cone shaped paper filter into the
cone filter basket.
8. Grind the correct amount of whole bean
coffee for the amount you are brewing.
1 level Breville scoop of ground coffee is
suitable for 150ml of water.
9. Select desired brewing mode, Fast, Gold,
MyBrew or Strong.
10. Press START|CANCEL to begin brewing.
SINGLE CUP/SMALLER VOLUMES
(LESS THAN 4 CUPS, 600ML)
1. Your Breville Precision Brewer will
recognize when the brewer has less than
4 cups (600ml) of water & will adjust the
brew settings, automatically, to make
the best possible tasting coffee. Fill your
cup with fresh cold water and then pour it
into the water tank, ensuring the water
level stays below the SINGLE CUP line.

Tips
WHOLE BEANS
• FRESH IS BEST! Freshly roasted, quality
coffee is key to making great tasting coffee.
Peak flavour potential is 5-20 days after roast.
Always look for a “Roasted On” date on the
bag. Avoid coffee with a “Best Before” or
“Use By” date as you never know when it
was roasted.
• Coffee flavour and strength are a personal
preference. Vary the type of coffee beans and
the amount of ground coffee to achieve your
preferred taste.
• Freshly ground beans are the key to
making coffee with more flavour and body.
Pre-ground coffee will have lost most of its
flavour and aromatics, so always grind right
before you brew for superior taste.
• Store coffee beans in a dark, cool and dry
place. Vacuum seal if possible.
• Buy coffee beans in small batches to reduce
the storage time and store no more than one
week’s supply at any time.
COFFEE/WATER RATIO
We recommend 1 level Breville scoop of coffee grounds per 150ml cup of water. Adjust the amount
according to your individual taste. The maximum capacity for pre-ground coffee is 12 level Breville
scoops. Exceeding this amount may cause the coffee basket to overflow.

PRE-GROUND COFFEE
• Pre-ground coffee is convenient, but will
never taste as good as coffee ground right
before you brew. We recommend investing in
a quality burr grinder so you can grind fresh
whole bean coffee right before you brew and
enjoy superior tasting coffee.
• The grind will affect the rate at which the
water flows through the coffee in the coffee
basket and therefore the taste of the coffee.
If the grind is too fine the water will not flow
through the coffee and may clog or overflow
the coffee basket. It may pass through the
mesh basket filter leaving sediment in the
cup or carafe. The resulting coffee will be
over extracted, too dark and bitter. If the
grind is too coarse the water will flow through
the coffee too quickly. This will result in an
under-extracted coffee lacking in flavour.
• Always use “drip filter grind” suitable for
use with a drip coffee machines. Never use
“Espresso grind” as the finer grind size may
cause the coffee basket to block and will be
over-extracted.
