Monthly backflush cleaning cycle
Run the machine's detergent backflush with the supplied cleaning disc and tablet to clear coffee oils from the group and three-way valve.
About monthly, or when the machine prompts a clean cycle; check your manual for the exact trigger.
Check your manual: Cleaning-cycle triggers and steps vary by firmware and model revision, so check your manual before running a clean cycle.
Step by step
- Insert the supplied grey rubber cleaning disc into the single-wall filter basket and drop in one cleaning tablet.
- Lock the portafilter into the group and start the clean cycle as described in the manual, letting the machine backflush detergent through the group (about 5 minutes).
- Remove and rinse the disc, portafilter and basket thoroughly, then run a water-only flush to clear any remaining detergent before brewing.
What you'll need

Breville Barista Express Impress maintenance questions
How often should I perform monthly backflush cleaning cycle?
Use the cadence above as a planning reminder, then follow the Breville Barista Express Impress manual because water hardness, usage, model revision, and machine alerts can change the interval.
Can I substitute a different cleaning procedure or product?
Do not assume procedures are interchangeable. Cleaning-cycle triggers and steps vary by firmware and model revision, so check your manual before running a clean cycle.
