Making a latte at home can be just as satisfying as ordering one at your favorite coffee shop, especially when you have a Breville espresso machine. In this guide, we’ll walk through how to make a perfect latte and how to properly descale your machine to keep your coffee tasting great and your machine running smoothly. We’ll also go over common descaling issues and how to prevent long-term problems. Let’s dive in.
Why Descaling Is Necessary
Descaling is the process of removing mineral buildup—mainly calcium and magnesium—from your espresso machine. These minerals come from the water you use and collect inside the internal components over time.
How Scale Buildup Affects Taste & Machine Efficiency
Flavor Change: Scale buildup can alter the flavor of your espresso. Coffee may taste bitter, metallic, or flat.
Temperature Issues: Minerals can coat heating elements, making it harder to reach or maintain the right brewing temperature.
Pressure Problems: Scale can clog internal tubes and valves, reducing water pressure. This affects espresso extraction and milk frothing.
Shorter Machine Lifespan: Ignoring scale buildup can lead to long-term damage, reducing the lifespan of your machine.
Signs Your Machine Needs Descaling
Watch for these signs that it’s time to descale your Breville espresso machine:
Slower water flow from the group head.
Loud or unusual pump noises.
Water doesn’t heat properly.
Coffee tastes off or smells strange.
Descale warning light (on certain models).
Choosing the Right Descaling Solution
There are several options when it comes to descaling solutions. Your choice depends on budget, availability, and machine compatibility.
Official De’Longhi Descaler
Even if you’re using a Breville machine, many descaling guides mention De’Longhi’s official descaler because it’s effective and safe for most machines.
Pros
Specifically made for coffee machines.
Gentle on internal parts.
Reliable and consistent.
Cons
More expensive than DIY options.
Not always available in local stores.
DIY Alternatives
1. White Vinegar
Mix 1 part vinegar with 1 part water.
Pros
Cheap and easy to find.
Works well for basic mineral removal.
Cons
Strong smell that can linger.
Can damage rubber seals if overused.
2. Citric Acid
Mix 1 tablespoon of citric acid powder per 1 liter of water.
Pros
Odorless.
Gentler than vinegar.
Safe for regular use.
Cons
Requires measuring and mixing.
Slightly slower action than commercial descalers.
Step-by-Step Descaling Guide
Follow these steps to safely descale your Breville espresso machine:
Step 1: Preparing the Machine
Turn off the machine and unplug it.
Remove the water tank and drip tray.
Empty both completely.
Remove the portafilter and clean it.
Step 2: Mixing the Descaling Solution
Mix your chosen descaling solution (store-bought, vinegar, or citric acid) with water according to instructions.
Fill the water tank with the solution.
Reinsert the water tank and drip tray.
Step 3: Starting the Descaling Mode
Plug the machine back in.
Turn on the machine and enter descaling mode. This varies by model but typically involves holding down buttons (refer to your manual).
The machine will begin drawing the solution through the boiler and out of the group head.
Let it run halfway, then pause for 10–15 minutes to allow the solution to work.
Resume until the tank is empty.
Step 4: Rinsing the Machine
Remove the tank and rinse it thoroughly.
Fill it with fresh, clean water.
Run a full cycle of clean water through the machine.
Repeat once more if necessary to ensure all solution is removed.
Troubleshooting Common Issues
What to Do if Scale Buildup Persists
Repeat the descaling process with fresh solution.
Use a stronger descaling mix if buildup is thick.
Check for clogs in the steam wand or group head.
Fixing Error Messages During Descaling
“Descale” Light Won’t Turn Off: Restart the descaling mode and complete all steps.
Water Flow Stops Mid-Cycle: Refill the tank and make sure it’s properly seated.
Beeping or Flashing Lights: Refer to your model’s manual; reset the machine if needed.
Addressing Strange Tastes or Smells
Run 2–3 full tanks of clean water through the machine.
Check the drip tray and portafilter for old coffee oils.
If smell lingers, try descaling with citric acid for a gentler clean.
Long-Term Maintenance Tips
How Often to Descale Based on Water Hardness
Soft Water: Every 3–4 months.
Medium Hardness: Every 2–3 months.
Hard Water: Every 1–2 months.
Use water test strips if you’re unsure about hardness.
Other Cleaning Habits for Optimal Performance
Daily: Rinse the portafilter and group head after use.
Weekly: Wipe down the steam wand, clean the drip tray and water tank.
Monthly: Backflush the machine using a cleaning disc and espresso machine detergent.
As Needed: Replace water filters and gaskets.
Conclusion
Making a great latte starts with a clean, well-maintained machine. Descaling your Breville espresso machine not only improves taste but also extends its life. Whether you use a store-bought descaler or a homemade solution, the key is consistency. By following these simple steps and staying on top of maintenance, you’ll enjoy café-quality lattes at home without the hassle. Don’t forget—clean water makes clean coffee, and clean coffee makes your mornings better.
