  • Continuous noise: If your machine is making a constant noise, it could be due to a problem with the pump, such as a blockage or damage.
  • Periodic noise: Hearing odd, sporadic noises might indicate an issue with the group head or the valve not working correctly. This can cause water blockage and prevent your machine from pumping water.

When you recognize these issues, you can take the appropriate steps to troubleshoot and, if necessary, seek professional help to get your Breville espresso machine back in working order.

  1. Remove the portafilter: Remove any coffee grounds and clean the portafilter thoroughly.
  2. Insert the blind basket: Place the blind basket into the portafilter, making sure it’s seated properly.
  3. Attach the portafilter: Attach the portafilter to the group head, ensuring it’s attached securely.
  4. Start the backflush: Turn on the pump for a few seconds and then turn it off. Repeat this process multiple times to push water and air through the valves, effectively unclogging the brew head.

Descaling the Espresso Machine

Hard water buildup can cause your espresso machine to malfunction.

Descaling helps remove mineral deposits and prolongs the life of your machine.

Follow these steps to descale your Breville espresso machine:

  1. Turn off the machine: Ensure your espresso machine is switched off before beginning the descaling process.
  2. Mix descaling solution: Prepare the descaling solution according to the manufacturer’s instructions. Fill the water tank with the mixture.
  3. Run the descaling cycle: Start the descaling cycle as per your machine’s manual. This will allow the descaling solution to flow through the machine, breaking down the mineral deposits.
  4. Rinse the machine: After the descaling cycle is complete, empty the water tank, rinse it thoroughly, and refill it with fresh water. Run the machine again to flush out any remaining descaling solution.
