Descaling Steps for a Breville Espresso Machine

Descaling is a crucial maintenance task for your Breville espresso machine.

Follow these steps to effectively descale your machine and keep it in optimal condition:

  1. Recognize the Need for Descaling:
    • The ‘Clean/Descale’ light will turn on to indicate that it’s time to descale your Breville machine.
  2. Prepare the Machine:
    • Remove the water tank and empty the drip tray.
    • Dissolve one packet of Breville’s descaling solution (or use a 1:1 water-vinegar mixture) into 1 liter of warm water.
    • Pour the solution into the water tank, and re-insert the tank into the machine.
  3. Enter the ‘Descaling’ Mode:
    • Ensure the machine is turned off.
    • Press and hold the ‘2-cup’ and ‘power’ buttons simultaneously to enter the descaling mode.
  4. Descale the Coffee Component:
    • Press the ‘1-cup’ button to initiate the descaling process for the coffee component of the machine.
  5. Descale the Steam and Hot Water Components:
    • Turn the steam dial left to descale the steam component.
    • Then, turn the steam dial right to descale the hot water component.
  6. Rinse the Machine:
    • Once the descaling process is complete, rinse the machine by filling the water tank with clean water.
    • Run a cycle without coffee grounds to flush out any remaining descaling solution.
  7. Repeat the Rinsing Process:
    • Repeat the rinsing process until there is no scent leftover from the descaling solution and the water runs clear.
  8. Regular Descaling Frequency:
    • To avoid clogging and water-related issues, descale your Breville machine every 3-6 months.
    • Some Breville models have a built-in clean/descale light that automatically illuminates when descaling is required.

Note: You can use a 1:1 water-vinegar mixture as an alternative descaling solution instead of Breville’s descaling solution. Ensure thorough rinsing afterward.

By following these steps and maintaining a regular descaling routine, you’ll ensure the longevity and optimal performance of your Breville espresso machine.

Refer to your specific model’s user manual for any additional descaling instructions or recommendations.

If you’ve performed the cleaning cycles but the “Clean Me” light on your Breville machine is still illuminated, don’t worry!
