Keeping your Breville coffee maker in top-notch condition requires regular maintenance, which includes the all-important descaling process. Over time, mineral buildup can occur and affect not only your coffee’s flavor but also your machine’s longevity. Descaling removes these mineral deposits, ensuring your coffee maker continues operating efficiently and producing the best-tasting coffee possible.

A comprehensive maintenance guide like this will teach you to descale your coffee maker, prevent potential damage, and improve your brewing results. With the right tools and techniques, descaling can be a simple addition to your coffee maker’s regular cleaning routine.

The Importance of Descaling Your Breville Coffee Maker

Descaling your Breville coffee maker is crucial to preserving the intricate workings of your machine and the quality of your coffee. A buildup of minerals can lead to blockages and corrosion, which, over time, could damage the machine irreparably. Regularly using a descaling agent will dissolve these deposits, ensuring each cup of coffee is as delicious as the last.

Impact of Scale Build-Up on Coffee Quality and Machine Performance

Mineral buildup in your coffee maker not only compromises the taste of your coffee but also impedes the machine’s performance. Scale can clog water lines, reduce heating efficiency, and cause uneven coffee extraction, leading to a subpar brew. In severe cases, it can even lead to machine failure. Therefore, removing these deposits using a descaling solution for your Breville coffee maker is essential for maintaining optimal machine health and coffee quality.

Recognizing When Your Coffee Maker Needs Descaling

Knowing when to descale your coffee maker is vital to maintaining its performance. A noticeable change in brewing time, a decrease in water temperature, or an increase in noise during brewing are all signs that mineral buildup is affecting your machine’s efficiency. 

If you spot any of these signs, it’s time to grab a descaling agent and give your Breville a thorough clean. A clean cloth can also help wipe away loose deposits after descaling.

Preparing Your Breville Coffee Maker for Descaling

Before beginning the descaling process, address any mineral buildup by removing the water filter and emptying the water tank. This preparation will allow the descaling agent to work directly on any scale present.

Set Up Your Machine for Descaling

Setting up your machine for descaling is straightforward. Start by ensuring that the reservoir is filled with the descaling solution and that any leftover coffee grounds or water won’t compromise the flavor of your coffee.

For effective maintenance, remove the water filter from your Breville coffee maker. This step is crucial as it allows the descaling solution to circulate through all the water channels without obstruction, ensuring a thorough clean when you descale your Breville coffee maker.

Next, empty the water tank completely to ensure no dilution occurs when adding the descaling solution. This way, when you start descaling your Breville coffee maker, the solution will be at the correct concentration to effectively remove any scale.

Selecting the Right Descaling Solution for Your Breville Coffee Maker

Selecting the right descaling solution is vital to prevent damage to your machine and effectively dissolve mineral buildup. While Breville may recommend specific solutions, alternatives such as a mixture of lemon juice and baking soda can also be effective if used correctly.

Breville’s Recommended Descaling Solution

Breville typically suggests using their proprietary descaling solution to combat mineral buildup. This is specifically formulated to be gentle on the machine’s internal components while being tough on scale, ensuring that your Breville coffee maker remains in peak condition after every use.

Using Vinegar or Citric Acid Solutions

Vinegar or citric acid solutions are popular alternatives if you prefer a homemade approach to descale your machine. Citric acid is a natural alternative descaling solution that, when mixed with water, can effectively break down mineral deposits without the harsh chemicals in some commercial solutions.

Descaling: A Step-By-Step Approach

You can execute the descaling process with the correct descaling solution selected and your machine prepared. Begin by ensuring that the reservoir of your Breville coffee is filled with the solution of your choice.

Step 1: Mixing the Solution and Filling the Reservoir

Start by mixing your chosen descaling solution in a measuring cup. Mix equal parts of water and a cup of vinegar if using a vinegar mixture. Once mixed, pour the solution into the water reservoir of your Breville coffee maker, preparing it for the descaling cycle.

Step 2: Initiating the Descaling Cycle

To initiate the descaling cycle, ensure the tank is empty and fill it with the descaling solution. Select the descale mode on your Breville coffee maker and wait for the power button to flash continuously, indicating that the machine is in descaling mode. If you’re using a commercial descaling solution, follow the manufacturer’s instructions carefully to avoid mishaps.

Step 3: Allowing the Solution to Work Through the System

After descaling the coffee component, it’s time to let the solution do its job. Press the button to start descaling the coffee cycle, then manually turn the steam dial for about 25 seconds. This will descale the steam wand. Wait for 8 seconds before turning the dial back to ensure the solution thoroughly cleans the internal parts of your Breville coffee maker.

When descaling your Breville coffee maker, it’s critical to adhere to the manufacturer’s recommended time for the descaling solution to sit in the machine. Coffee machines require precise temperature control during the descaling process to ensure the solution effectively breaks down the mineral deposits without damaging sensitive heating elements.

Step 4: Completing the Descaling and Rinsing Thoroughly

After allowing the solution to sit for about 20 minutes, flush the machine by running a cycle with fresh water. Rinse the water reservoir, empty the drip tray, and place the drip tray and water tank back into the machine. It’s crucial to remove all coffee grounds and commercial solutions to maintain your coffee’s taste and quality.

To guarantee that no descaling solution remains, unplug the machine and run at least three cycles of plain water through the system. This final rinse is essential in removing any remaining solution and ensuring your next cup of coffee is as pure and flavorful as possible.


Regular descaling of your Breville coffee maker is a crucial step in maintaining the longevity of your machine and ensuring that each cup of coffee it brews meets your expectations for quality. The descaling process is straightforward, but it’s essential to refer to your machine’s instruction manual for specific instructions tailored to your model. 

After descaling your Breville coffee maker, wipe it down with a soft cloth or sponge to keep it looking as great as it performs. With regular descaling and maintenance, your coffee maker will continue to produce delightful cups of coffee for years to come.
