Your Breville espresso machine is only as good as the basket you use. Over time, stock baskets can wear out, get clogged, or limit your ability to pull consistent shots. Whether you’re swapping between single and double shot baskets, upgrading to a precision model, or just replacing an old one, learning how to change your Breville portafilter basket is a simple but important skill.
In this guide, we’ll show you exactly how to remove and replace your basket, explain the different types available, and share tips for getting the best fit and performance out of your setup.
Step-by-Step Guide to Changing a Breville Portafilter Basket
Changing the basket is quick once you know the process, but it helps to follow the right steps to avoid damaging the portafilter or basket.
Removing the Old Basket
Start by unlocking your portafilter from the group head and knocking out any used puck. Place the portafilter face-up on a towel. Using a basket removal tool (often included with the machine) or the back end of a spoon, gently pry the basket out of the portafilter. Avoid using sharp objects that could scratch the metal. Scratches lead to premature wear.
Cleaning Before Replacement
Before inserting the new basket, give the portafilter a thorough cleaning. Rinse away any oils or residue, and use a small brush if necessary to scrub inside the lip where the basket sits. A clean portafilter ensures your new basket fits snugly and reduces the risk of leaks during brewing.
Inserting the New Basket
Align the new basket with the portafilter rim and press down firmly until it clicks into place. It should sit flush with no wobble. If it feels loose, double-check that you’re using the correct size (54mm for Breville Bambino, Barista Express, and similar models). With the basket in place, run a quick rinse cycle through the group head to confirm a secure seal.
Types of Breville Portafilter Baskets
Not all baskets are created equal. Breville offers several types, and upgrading to precision options can dramatically improve consistency and flavor.
Single vs. Double Shot Baskets
Breville machines typically come with single (1-cup) and double (2-cup) baskets. Single baskets hold less coffee but are harder to dial in, while double baskets are more forgiving and preferred by most home baristas. Switching between them is easy once you know how to change your basket.
Pressurized vs. Non-Pressurized Baskets
Pressurized baskets have a single exit hole and are more forgiving for beginners, as they mask inconsistencies in grind size or tamping. Non-pressurized baskets (also called single-wall baskets) require precision but reward you with richer crema and better flavor clarity. Many Breville owners upgrade to non-pressurized baskets once they gain confidence.
Precision Baskets (Upgrades)
Precision baskets, like those from Pesado, feature uniform hole sizes and patterns for even extraction. They’re engineered to improve consistency and unlock more complex flavors from your beans. For intermediate and advanced users, upgrading to a precision basket is one of the fastest ways to elevate your Breville’s performance.
Knowing your basket types makes it easier to choose upgrades, but maintaining them properly ensures they perform at their best over time.
Tips for Maintenance and Best Results
A clean, well-fitting basket will give you more consistent espresso and extend the life of your equipment.
Regular Cleaning Routine
After every shot, knock out the puck promptly and rinse the basket with hot water. Coffee oils build up quickly and can turn rancid, affecting flavor. A weekly soak in a coffee cleaning solution keeps baskets free from stubborn residue.
Ensuring the Right Fit
Always confirm you’re using the correct basket size for your machine. Breville machines like the Barista Express and Bambino use 54mm baskets, while larger models like the Dual Boiler use 58mm. A poor fit leads to leaks and uneven extraction.
When to Replace Your Basket
Even stainless steel baskets wear down over time. If you notice warped edges, inconsistent holes, or stubborn clogging, it’s time to replace. Upgrading to a precision basket not only solves wear issues but also improves performance, making it a worthwhile long-term investment.
Upgrade Your Breville with Confidence
Changing a Breville portafilter basket is simple, but the benefits are significant. Whether you’re moving from pressurized to non-pressurized, swapping basket sizes, or upgrading to precision-engineered options, a proper basket sets the foundation for every great shot.
Pesado’s precision baskets are designed to fit Breville machines perfectly, delivering smoother, more consistent extractions with every use. Pairing a high-quality basket with Pesado tampers and distribution tools ensures your setup performs at its peak, so every shot of espresso tastes like it came from a café.
