The Breville Bambino Plus BES500 is a compact espresso machine that relies on a dedicated group‑head cleaning cycle to keep the portafilter and brew head free of coffee residue. The cycle is triggered automatically after 200 extractions, indicated by the 1 CUP and 2 CUP buttons flashing alternately. It is a separate process from descaling, which uses a different alert pattern and a descaling powder.

What the Cleaning Cycle Does (and Doesn’t Do)

  • • Cleans the group head and portafilter by flushing a cleaning tablet through the brew path.
  • • Does not clean the boiler, steam wand, or internal water lines.
  • • Is distinct from the descaling procedure, which targets mineral buildup inside the machine.

Recognizing the Cleaning‑Cycle Alert

After 200 extractions, the 1 CUP and 2 CUP buttons will flash alternately. This pattern is unique to the cleaning cycle. The descale alert, in contrast, flashes the 1 CUP and STEAM buttons alternately with the 2 CUP button for 15 seconds. Source

  1. Insert the cleaning disc into the filter basket of the portafilter. Source
  2. Place a cleaning tablet on top of the disc. Source
  3. Lock the portafilter into the group head. Source
  4. Empty the drip tray, replace it on the machine, and place a 2 L container under the portafilter and steam wand. Source
  5. Fill the water tank to the MAX line and reattach it, ensuring it is correctly seated. Source
  6. Press and hold the 1 CUP and 2 CUP buttons for 5 seconds to enter cleaning‑cycle mode. Source
  7. When the 1 CUP and 2 CUP buttons remain illuminated, press either button to start the cycle; the lights will flash alternately while the cycle runs. Source
  8. Wait until the cycle completes and the machine returns to ready mode. Source
  9. Remove and rinse the portafilter, cleaning disc, drip tray, and container. Source

Manual Early‑Entry Option

If you want to run the cleaning cycle before the 200‑extraction alert appears, you can manually enter the cycle from off mode by pressing and holding the 2 CUP and STEAM buttons simultaneously for five seconds. All lights will be off during this entry. Source

Key Takeaways for the User

  • • The cleaning cycle is only for the group head; descaling is a separate process.
  • • Use the cleaning disc and tablet supplied with the machine; do not substitute descaling powder.
  • • The 5‑second hold of 1 CUP + 2 CUP is the entry method for the cycle when the alert appears.
  • • After the cycle, the machine automatically returns to ready mode; you only need to remove and rinse the components.

Following these manufacturer‑specified steps ensures your Bambino Plus stays clean and ready for the next espresso shot. For more on descaling or steam‑wand cleaning, refer to the separate sections in the Breville manual.
