How To Backflush Your Breville Barista Express: The Complete Guide
Backflushing your Breville Barista Express is essential for maintaining optimal performance and prolonging its lifespan. In short, you backflush your machine with a cleaning tablet to remove built-up coffee oils and residue, and without a tablet to rinse the system thoroughly.
Introduction to Backflushing
The Breville Barista Express is a fantastic entry-level espresso machine that allows home baristas to pull delicious shots. However, like all espresso machines, it requires regular maintenance to function correctly. One of the most important maintenance procedures is backflushing. Backflushing involves forcing water through the machine’s group head in reverse, pushing out accumulated coffee oils and grime that can affect the taste of your espresso and the machine’s overall performance. Failing to backflush regularly can lead to bitter-tasting coffee, clogged components, and ultimately, machine failure.
Why Backflush Your Breville Barista Express? Understanding the Benefits
Backflushing provides several crucial benefits that contribute to the longevity and performance of your Breville Barista Express. These benefits include:
- Improved Espresso Quality: Removing old coffee oils prevents them from tainting the flavor of your freshly brewed espresso. This results in a cleaner, brighter, and more balanced cup.
- Prevention of Clogs: Coffee oils and residue can accumulate and harden over time, leading to clogs in the group head, brew pathways, and other vital components. Backflushing helps prevent these clogs, ensuring consistent water flow and pressure.
- Extended Machine Lifespan: Regular cleaning through backflushing reduces the strain on the machine’s components, preventing premature wear and tear. This helps extend the lifespan of your Breville Barista Express.
- Improved Hygiene: Backflushing helps eliminate bacteria and mold growth that can thrive in the warm, moist environment of an espresso machine.
How Do I Backflush a Breville Barista Express?: A Step-by-Step Guide
Here’s a detailed guide on How Do I Backflush a Breville Barista Express?:
Materials Needed:
- Breville Barista Express
- Breville backflushing disk (or a blank portafilter basket)
- Espresso machine cleaning tablets
- Drip tray
- Water
Backflushing Procedure (with cleaning tablet):
- Prepare the Portafilter: Insert the backflushing disk into your portafilter.
- Add Cleaning Tablet: Place one espresso machine cleaning tablet on top of the backflushing disk.
- Lock the Portafilter: Securely lock the portafilter into the group head, just as you would when making espresso.
- Initiate the Cleaning Cycle:
- Refer to your Breville Barista Express manual for specific cleaning cycle instructions. This often involves pressing and holding two buttons (usually the 1-cup and 2-cup buttons) simultaneously while turning the machine on.
- Alternatively, you can manually run the machine for approximately 10 seconds, then let it sit for 10 seconds. Repeat this cycle 5-10 times.
- Rinse the Portafilter: Remove the portafilter and thoroughly rinse it under running water to remove any residual cleaning solution.
- Rinse the Group Head: Lock the empty portafilter (with the backflushing disk) back into the group head and repeat step 4 using only water. This will rinse any remaining cleaning solution from the machine. Repeat this cycle 5-10 times.
Backflushing Procedure (without cleaning tablet – daily):
- Prepare the Portafilter: Insert the backflushing disk into your portafilter.
- Lock the Portafilter: Securely lock the portafilter into the group head, just as you would when making espresso.
- Initiate the Cleaning Cycle: Manually run the machine for approximately 10 seconds, then let it sit for 10 seconds. Repeat this cycle 5-10 times.
Frequency:
- Backflush with a cleaning tablet: Every 200 shots or approximately once a month.
- Backflush without a cleaning tablet: Daily.
Common Mistakes to Avoid When Backflushing
Avoid these common mistakes to ensure you backflush your Breville Barista Express effectively and safely:
- Using the Wrong Cleaning Tablets: Always use cleaning tablets specifically designed for espresso machines. Dish soap or other household cleaners can damage the machine.
- Overusing Cleaning Tablets: Using too many cleaning tablets or backflushing too frequently with tablets can damage the machine’s internal components. Follow the manufacturer’s recommendations.
- Skipping the Rinsing Step: Failing to thoroughly rinse the machine after backflushing with a cleaning tablet can leave residual cleaning solution, which can affect the taste of your espresso.
- Forgetting to Daily Backflush: Skipping the daily water-only backflush is a common oversight. This keeps the machine clean and minimizes the need for the deeper clean with tablets.
- Ignoring the Manual: Always consult your Breville Barista Express manual for specific instructions and safety precautions.
How Often Should You Backflush? A Recommended Schedule
The frequency of backflushing depends on your usage. Here’s a recommended schedule:
| Cleaning Type | Frequency | Rationale |
|---|---|---|
| Daily Backflush | After each use | Removes loose coffee oils, preventing buildup. |
| Backflush with Tablet | Monthly (or 200 shots) | Provides a deeper clean, removing stubborn residue and preventing clogging. |
Frequently Asked Questions (FAQs)
Why is backflushing so important for my Breville Barista Express?

How do I know if my Breville Barista Express needs backflushing?
Signs that your Breville Barista Express needs backflushing include bitter-tasting espresso, reduced water flow, and inconsistent shot times. If you notice any of these symptoms, it’s time to backflush your machine.
Can I damage my Breville Barista Express by backflushing too often?
Yes, over-backflushing with cleaning tablets can damage your Breville Barista Express. It can lead to premature wear of seals and other internal components. Stick to the recommended frequency of backflushing with tablets (approximately once a month).
What kind of cleaning tablets should I use?
Use cleaning tablets specifically designed for espresso machines. Look for tablets that are non-toxic, biodegradable, and safe for use with food-grade materials. Breville sells its own cleaning tablets, but other brands like Cafiza are also suitable.
Do I need to remove the shower screen before backflushing?
No, you do not need to remove the shower screen before backflushing. The backflushing process is designed to clean the entire group head, including the shower screen.
My Breville Barista Express has a “Clean Me” light. Does that mean I need to backflush?
The “Clean Me” light on your Breville Barista Express indicates that it’s time for a thorough cleaning cycle, which includes backflushing. It’s important to follow the backflushing procedure when the light illuminates.
Can I use a regular portafilter basket instead of a backflushing disk?
No, you must use a backflushing disk or a blank portafilter basket. A regular portafilter basket has holes that allow water to flow through, rendering the backflushing process ineffective.
What should I do if my Breville Barista Express is still clogged after backflushing?
If your Breville Barista Express remains clogged after backflushing, you may need to disassemble the group head and manually clean the components. Refer to your Breville Barista Express manual for instructions on how to do this safely. If you’re not comfortable with this process, consider consulting a qualified technician.
Is descaling the same as backflushing?
No, descaling and backflushing are two different maintenance procedures. Descaling removes mineral buildup from the machine’s internal components, while backflushing removes coffee oils and residue from the group head. Both are essential for maintaining optimal performance.
Where can I find the backflushing disk for my Breville Barista Express?
The backflushing disk should have come with your Breville Barista Express. If you’ve lost it, you can purchase a replacement from Breville’s website or from online retailers. Search for “Breville backflushing disk.” A blank portafilter basket will also work.
