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 move up and down.


  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
  1. 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.



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.

CAUTION: Filling the basket without a mesh basket filter or filter paper may cause the basket to overflow during the brewing cycle.

  1. The LCD will display the basket setting – “Basket” or “Cone”. To change the basket type, rotate the SELECT dial to Settings & press the dial. Rotate the SELECT dial to the basket type, press the SELECT dial to set.
  2. Fill the water tank with fresh cold water up to the MAX marking on the water tank.

NOTE: This machine will brew all the water in the tank. Ensure the tank does not contain an excess amount of water.

  1. 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.
  2. 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.
  3. 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.

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.

  1. 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.

  1. 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
  2. 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.


• 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.

• 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.


  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.

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.

  1. Place your empty cup underneath the brew basket outlet.
  2. We recommend using cone filter basket insert for single cups. It ensures proper contact between the brew water and the ground coffee.
  3. To change the basket type, rotate the SELECT dial to Settings and press to enter the Settings mode and select “Basket Type”.
  4. Rotate the dial to select “Cone”, and press dial to select. “Cone” will be displayed on the LCD.
  5. Insert the Cone filter basket into the brew basket. Use the alignment marks as a guide.
  6. Place a cone shaped paper filter into the cone filter basket.
  7. 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.
  8. Select desired brewing mode, Fast, Gold, My Brew or Strong.
  9. Press START|CANCEL to begin brewing.

• 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.


• 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.


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.

• When coffee is roasted, CO2 is trapped inside the bean. Coffee grounds release this CO2 when hot water hits them, and this is called “blooming”. Your Brewer can automatically adjust bloom time by controlling the water flow. Blooming can have an impact on the aromas and flavours of the brewed cup. If the coffee is overly bitter shorten bloom time, and if it’s sour make it a little longer.


• Pre-heat the carafe or cup for best results. A pre-heated carafe or cup will help maintain the coffee’s optimal temperature and keep coffee hotter for longer. Fill with hot water for about 30 seconds then discard the water.


• Fresh, good-tasting water is essential for a perfect cup. If the water contains excessive sediment, or has an ‘off’ taste or odor, we recommend using filtered water.


• Iced coffee is at its best when the coffee is brewed strong because the coffee is diluted by the melting ice cubes. To achieve great Iced coffee we recommend brewing in OVER ICE mode. Fill the tank ensuring the water level does not exceed the 600ml level.
• Fill the brew basket with twice the amount of coffee you’d normally use for regular brewed coffee.
• Brew into the carafe.
• Once the brewing cycle is complete, transfer the coffee to a heatproof pitcher and let cool to room temperature. Refrigerate until cold, at least 2 hours or overnight. Fill glasses with ice cubes. Pour the coffee into the glasses, filling them to within 4cm of the rim. Top each glass with cream, milk, syrups or sweeteners as desired.

NOTE: If using granulated sugar as a sweetener, add while the coffee is hot to encourage the sugar to completely dissolve.

• To avoid a diluted taste, you can also use regular strength coffee and serve it over coffee ice cubes. Prepare coffee ice cubes by pouring cool coffee into ice-cube trays and freezing.


Your Brewer will produce a maximum of 600ml of Cold Brew. Due to the long duration (typically 4-14 hours) of the brewing process we recommend setting the machine up overnight so the Cold Brew will be ready in the morning.

  1. Fill the tank with your desired volume of water ensuring this is below the COLD BREW line.
  2. Remove the basket, and ensure both the cone insert and mesh basket filter are removed. Add a large paper filter and then coffee at 2-3 times of regular ratio (approximately 12 scoops for 600ml). Reinsert the basket into the machine.
  3. Remove the lid from the carafe and re-insert – the lid must not be on the carafe during the brewing process, alternatively, use another vessel.
  4. Navigate to the COLD BREW setting and press START|CANCEL. The machine will then begin brewing the water without the heating element. Once this is complete a countdown timer will display on the LCD indicating when the Cold Brew is finished. At this point the machine will automatically dispense the Cold Brew into the waiting carafe.

NOTE: Brew Time for Cold Brew can easily be adjusted to your preference, anywhere between 5min – 24hrs.
NOTE: Do not add ice to the tank. Cold, chilled water should be added.
NOTE: Ensure the carafe lid is removed for Cold Brew mode.

Care & Cleaning

Always turn the coffee machine off and remove the plug from the power outlet before cleaning.


The outer housing and LCD screen can be cleaned with a soft, damp cloth. Apply cleaner to the cloth and not the LCD surface. Polish with a soft, dry cloth. Cleaning and drying with dry paper towels or abrasive cloths and cleaners may scratch the surface.


Remove the coffee basket. Discard any ground coffee and filter paper. The coffee basket and mesh basket filter can be rinsed under running water. Ensure the fine holes of the mesh basket filter are clear. For a deeper clean, wash the coffee basket and mesh basket filter in warm, soapy water with a soft bristled brush.

CAUTION: The coffee basket, mesh basket or paper filter may still be very hot after brewing. Use caution and allow to cool before removing.


After each use, empty the carafe. Do not let brewed coffee stand overnight as this can cause the carafe to stain. Rinse the carafe and carafe lid under warm running water. For a deeper clean, we recommend regularly washing the carafe in warm, soapy water using a soft bristled brush. Do not use abrasive cleansers, pads or cloths which can scratch the surface. Rinse and dry thoroughly.


Simply wipe down the showerhead area periodically. However, if a more thorough clean is required, the Showerhead can be removed by unlocking the Showerhead Ring. Rotate clockwise then remove the Showerhead for cleaning. Once complete, reinstall the Showerhead.


After regular use, hard water can cause mineral build up in internal components, reducing the brewing flow, brewing temperature, power of the machine, and taste of the coffee. We recommend to descale regularly. When CD shows “DESCALE” (flashing), descaling cycle is needed.

NOTE: It takes approximately 15 minutes to complete descaling cycle.

  1. Empty the tank. Prepare a descale solution in accordance with manufacturer’s instructions. Pour this solution into the empty water tank.
  2. Place the basket and the carafe into position under the drip stop outlet (Ensure the carafe is empty and the lid is securely locked).
  3. Press SELECT button for 3 seconds to start descaling cycle. LCD with show “dSL” for 1 second and then tell remaining time of descaling cycle.
  4. When the descaling process is finished, the LCD screen will go back to the main menu. To completely remove residual water in the tank, invert the machine and brew with fresh water twice. Discard the water from the carafe and rinse thoroughly.

NOTE: We recommend to brew through again after descaling to brew out the residue descale solution.

NOTE: You cannot stop the descaling process mid cycle. Force stop by unplugging the cord from the power outlet.


This is to reset the machine to the factory settings, including water hardness setting. Hold the START button, the SELECT button, and AUTO START button altogether for 3 seconds. When LCD shows “rES” (flashing), press SELECT button to start. Then next prompt asks “YES” or “no” to confirm. Rotate and press
SELECT dial/button.
