The Breville Bambino Plus is designed to be simple, but its cleaning cycle is still essential for great-tasting espresso. Coffee oils build up in the group and internal pathways, and the Bambino Plus includes a cleaning alert that reminds you when it is time. The cleaning cycle uses a cleaning disc and tablet to backflush the group, similar to larger Breville machines but tailored to the Bambino Plus.
What You Need
- The cleaning disc included with the Bambino Plus
- A cleaning tablet for espresso machines
- The single-wall 1 cup filter basket

Step-by-Step Cleaning Cycle
1. Prepare the portafilter
Insert the 1 cup single-wall basket. Place the cleaning disc inside, then put one cleaning tablet on top.
2. Lock it in
Lock the portafilter into the group and empty the drip tray.
3. Start the cycle
Use the button combination listed in your manual to start the cleaning cycle. The machine will pulse water through the group for several minutes.
4. Let it finish
The cycle takes roughly 5 minutes. When complete, the cleaning alert should clear.
5. Check the tablet
Remove the portafilter and confirm the tablet dissolved. If not, run the cycle again.
6. Rinse
Rinse the disc and basket. Run water through the group, then pull a sacrificial shot.
How Often to Clean
Run the cleaning cycle when the alert appears. If you use dark roasts or make several drinks daily, you may want to clean more often, roughly every 2-4 weeks.
Bambino Plus Milk System Care
Steam wand
The Bambino Plus automatically purges the steam wand after use, but milk residue can still build up. Wipe the wand after every use and clear the steam tip with the cleaning pin weekly.
Temperature sensor
The milk temperature sensor sits where the pitcher rests. Clean it with a damp cloth to keep automatic frothing accurate.
Milk pitcher
Rinse the pitcher immediately after use. Dried milk can affect the sensor and hygiene.
Bambino Plus Details That Trip People Up
Use the single-wall basket, not the dual-wall
The Bambino Plus ships with single-wall and dual-wall baskets in 1 cup and 2 cup sizes. The cleaning disc is sized to sit flat in the 1 cup single-wall basket. In a dual-wall basket it can sit crooked, and the small exit hole in the pressurized floor changes how pressure builds, so the cycle may finish without properly flushing the group.
Empty the drip tray first
The cleaning cycle sends a fair amount of dirty water into a fairly shallow tray. Because the milk temperature sensor sits on that same tray, a full tray can splash detergent water onto the sensor plate. Empty it before you begin and wipe the plate afterward.
Run it with a warm machine
Cleaning tablets dissolve best in hot water. Pull a blank shot of water first so the ThermoJet and group are up to temperature before you start the cycle.
Clean the 54 mm group gasket area
The cycle cleans behind the shower screen, but coffee grounds collect around the edge of the 54 mm gasket where the portafilter seals. Brush that ring after every few sessions, especially if you use a funnel and dose 18-19 g in the double basket, which sits close to the screen.
Signs You Need a Cleaning Cycle
- Cleaning alert lights
- Bitter or stale taste
- Coffee residue visible on the shower screen
- Water dripping from the group
Common Problems
Tablet does not dissolve
Run another cleaning cycle and ensure the disc is seated correctly.
Alert stays on
Confirm you used the correct basket and disc, then repeat the cycle.
Leaks around portafilter
Lock the portafilter firmly. If leaks persist, the group gasket may need replacement.
FAQ
Is the cleaning cycle the same as descaling?
No. The cleaning cycle removes coffee oils. Descaling removes mineral buildup and uses a separate mode.
Can I use a blind basket instead of the disc?
The disc is designed for the Bambino Plus. A blind basket may fit but can change pressure behavior; use the disc for consistent results.
Bottom Line
Backflush your Breville Bambino Plus by running the cleaning cycle with the disc and tablet in the 1 cup basket. Do it when the alert appears or more often if you use oily coffees. Keep the steam wand and temperature sensor clean to maintain both espresso quality and milk texture.
