How-To: Cleaning a Breville espresso machine

Cleaning your Breville espresso machine is important. And if you follow Breville’s manual: you’ll take much longer completing the process. Here’s the ultimate guide to cleaning a Breville.
Regular cleaning is crucial for keeping your Breville espresso machine running in top working order and delivering flavorful coffee. This routine maintenance prevents buildup and sanitizes components.
Cleaning differs from descaling in that it focuses on removing oils, coffee residues, and bacteria rather than mineral deposits.
Overview of Cleaning Breville Espresso Makers



During the coffee brewing process, oils and residues accumulate on components like the brew head screen, steam wand, water reservoir, and milk container. Bacteria and mold can also propagate.
Allowing this buildup can lead to:
- Off tastes and odors imparting to coffee
- Clogged or sticky components
- Promotion of bacteria growth
- Reduced lifespan of parts
Regular cleaning removes buildup to keep your Breville machine running cleanly and prevent premature wear. Most manufacturers recommend full cleaning every 2-4 weeks.
The cleaning process typically involves:
- Removing removable components
- Washing removable parts with detergent
- Using cleaning tablets to backflush and sanitize
- Scrubbing exterior surfaces
Below we’ll detail the recommended cleaning procedures for Breville’s various home espresso machines using their included detergents and tools.
Don’t forget to descale your Breville espresso machine every 2-3 months, according to the company.
How To clean a Breville espresso machine
To clean a Breville espresso machine you’ll need some cleaning tools:

Breville includes cleaning tablets designed to dissolve oils and residues when backflushed through the group head.
What you will need for this is a cleaning tablet, the plastic backflushing disc and the 1 CUP filter.



Place a tablet into the provided plastic backflushing disc.
Insert disc into portafilter basket and lock into the group head.

Make sure the water tank is filled up to the maximum with fresh cold water.
Here it comes: Breville advises to put a big tray under the group head. Don’t do this!

It took me about 5 minutes to find a huge tray that will fit under the group head. I removed the upper-part of the drip tray to make it fit on Breville’s Barista Express.
Believe it or not, but after the cleaning cycle this tray was EMPTY. So, don’t do this. I ran the cleaning cycle again without it and there was no difference.
Just leave the drip tray, the water will flow there from inside the machine.
Starting the cycle
Now press power to shut down the machine.
Press the buttons 1 CUP, 2 CUP and Power at the same time. Hold for 10 seconds.

The cleaning cycle starts and takes about 5 minutes. Water runs out the inside of the machine into the drip tray.
When finished, the Breville will make two short sounds. Remove the portafilter and check if the tablet is dissolved.
Is the tablet dissolved? Congratulations, you’re done.
Tablet still not dissolved? Repeat the process until it’s gone.
