Why Descaling is Important

Why Descaling is Important, breville coffee maker

Descaling your Breville coffee maker on a regular basis is crucial to maintaining optimal performance and longevity. Over time, mineral deposits like calcium and limescale can build up inside the machine from the water. Failing to descale can lead to some significant issues:

  • Reduced brewing efficiency – Mineral buildup in areas like the heating element can affect how quickly and evenly water is heated, leading to inconsistent extraction. This can result in coffee that is under-extracted or over-extracted, altering the flavor.
  • Altered coffee tasteLimescale and other deposits can give your coffee an unusual metallic, bitter, or sour taste. Coffee experts note that scale buildup is one of the most common reasons for a decline in coffee quality over time.
  • Clogged components – Buildup in small tubes like the water lines, solenoid valves, and thermoblocks can restrict water flow and potentially clog the machine entirely. Clogs force the machine to work harder, reducing performance.
  • Corrosion and damage – Left unchecked, mineral deposits can corrode metal components like the boiler and heating element and cause permanent pitting or damage. Corrosion can lead to leaks or machine failure.
  • Bacteria growthLimescale provides an environment for bacteria like E. coli and mold to multiply, posing a health risk if allowed to enter your brewed coffee.

Descaling helps prevent all these problems by dissolving mineral buildup and flushing it from the system. Without descaling, your expensive Breville coffee maker will experience reduced performance and shorter lifespan.

Some signs it’s time to descale include:

  • Longer warm-up times
  • Uneven water flow
  • Weak or sputtering brewing
  • Strange mineral taste
  • Error codes on display
  • Visible scale buildup

By descaling every 3-6 months, you can optimize your Breville coffee maker’s performance, improve coffee flavor, extend its lifespan, and avoid costly repairs down the road. It’s a small investment of time that pays major dividends!

What You’ll Need

Descaling your Breville coffee maker is a straightforward process, but having the right supplies on hand is key. Here’s an overview of what you’ll need:

Descaling Solution

  • Use a commercial descaling solution made specifically for coffee equipment. Popular options like Urnex Dezcal and Impresa Descaler are safe for Breville machines.
  • Citric acid can be used as a more affordable, natural descaling agent. Mix 1 tbsp of citric acid per 16 oz of water.
  • Avoid vinegar or other acids like acetic acid if your machine contains aluminum components. Vinegar can damage aluminum over time.


  • Water – Use filtered water if possible to prevent future mineral buildup.
  • Large bowl or sink – To catch the used descaling solution that drains out.
  • Towels – For wiping up spills and drips. Lay towels under the machine.
  • Gloves – Wear rubber gloves when handling descaling solutions.
  • Eye protection – In case of splashing during the descaling process.


  • Breville user manual – Follow the descaling instructions specific to your Breville model. Steps may vary.
  • YouTube tutorial – Search for a video on descaling your specific Breville machine model for a visual guide.
  • Breville support – Call Breville support if you have any questions before descaling.

Only use solutions designed for coffee equipment to avoid damage. Check your manual for Breville’s recommended descaling frequency and process. Never mix chemical descaling agents.

Step-by-Step Descaling Process

Descaling your Breville machine involves a few simple steps. Be sure to follow the instructions for your specific model found in the user manual. The general process is:

  • Prepare the coffee maker
  • Remove key parts like the water filter, portafilter, carafe, drip tray, etc. Refer to manual.
  • Drain any water from the reservoir and internal tanks.
  • Fill reservoir with descaler
  • For liquid descalers, mix with water per package directions.
  • For citric acid, use 1 tbsp per 16 oz water.
  • For vinegar, use equal parts vinegar and water.
  • Run descaling cycle
  • Initiate the descaling mode listed in your manual, often by pressing “Clean” or “Descale”.
  • Allow solution to circulate for full duration, usually 30+ minutes.
  • Rinse thoroughly
  • Drain descaling solution completely.
  • Refill reservoir with fresh water.
  • Run 2-3 cycles with only water to rinse.
  • Flush the system
  • Brew 2-3 full batches of plain water through the machine.
  • Discard the output water – don’t drink it.
  • Clean and reassemble
  • Wipe down exterior with a damp cloth.
  • Rinse and replace any parts removed earlier.

Tips for the process:

  • Lay down towels in case of drips or splashes.
  • Wear gloves when handling descaling solutions.
  • Follow all steps carefully to fully rinse the machine.
  • Never interrupt or pause the descaling cycle.
  • Prep a large sink or container to catch used liquid.
  • Expect hissing sounds as the solution dissolves deposits.

Be sure to descale regularly every 3-6 months for optimal performance. Always use solutions formulated for coffee equipment.

Alternative Descaling Solutions

While Breville recommends their proprietary descaling solutions, there are some effective homemade alternatives:

Alternative Descaling Solutions, vinegar and lemon juice in bottles, whole lemons on the table


  • White distilled vinegar works well due to the acetic acid.
  • Use a 50/50 ratio of vinegar to water.
  • Rinse thoroughly after descaling to avoid any vinegar taste.
  • Avoid malt vinegar, apple cider vinegar, etc. – the flavor can linger.

Citric Acid

  • Sold as a powder or crystallized citric acid.
  • Mix 1 tablespoon per 16 oz of water.
  • Provides natural descaling without odors.
  • Can be found online or sometimes in stores near canning supplies.

Lemon Juice

  • Freshly squeezed lemon juice contains citric acid.
  • Use a 1:2 ratio of lemon juice to water.
  • May require several lemons for a full reservoir.
  • Rinse machine well after to avoid lemon flavor.

Other Acid Solutions

  • Phosphoric acid found in some rust removers. Use extreme caution and dilute very well.
  • Acetic acid is sold as a concentrated descaling solution. Follow dilution instructions carefully.

When using any homemade descaling solution:

  • Wear gloves and eye protection for safety.
  • Rinse machine thoroughly with plain water after descaling.
  • Run 2-3 cycles of fresh water through the machine.
  • Discard the first few batches of coffee to remove any taste.

Vinegar, citric acid, and lemon juice offer affordable and effective options compared to commercial descalers. Always follow descaling steps carefully and rinse fully afterward.

Tips for Ongoing Maintenance


  • Descale every 3-6 months with vinegar, citric acid or a commercial descaler to prevent mineral buildup.
  • Refer to descaling instructions in your model’s owner’s manual.
  • Schedule descaling on your calendar to remember.


  • Wipe down the exterior, drip tray, and other surfaces regularly with a damp cloth.
  • Clean portafilter, filter baskets, and group head weekly with cafiza or espresso cleaning powder.
  • Rinse steam wand after each use to prevent milk buildup. Wipe with a damp cloth.
  • Empty drip tray often to prevent overflow.
  • Backflush the group head monthly to clean inside. Use cleaning tablets.

Water Filtration

  • Use filtered water to help reduce scale-causing minerals.
  • Change the filter cartridge every 1-2 months per manufacturer recommendations.

Parts Replacement

  • Replace parts like gaskets, O-rings, and seals periodically as suggested in manual.
  • Inspect parts while cleaning and replace if cracked or worn.

Preventative Maintenance

  • Schedule periodic maintenance checks with a technician to keep machine in optimal condition.
  • Technician can inspect internal components and perform tune-ups.
