Step-by-Step Guide To Backflushing

Now that you have the necessary tools and materials, let’s dive into the step-by-step guide on how to backflush your Breville Barista Express:

Step 1: Prepare The Espresso Machine For Backflushing

Step 2: Insert The Blind Filter Into The Portafilter

The blind filter is a specialized filter with no holes. It is necessary for backflushing as it allows pressure to build up within the group head, helping to remove any built-up residue or blockages. Insert the blind filter securely into the portafilter.

Step 3: Add A Cleaning Agent Into The Blind Filter

Choose a suitable espresso machine cleaner or backflush detergent. Follow the instructions provided by the manufacturer to determine the appropriate amount of cleaner to use. Generally, a small amount (about the size of a dime) is sufficient. Place the cleaner into the blind filter.

Step 4: Start The Backflushing Process

With the blind filter inserted and the cleaner added, it’s time to begin the backflushing process. Gently but firmly lock the portafilter back into the group head. Make sure it is properly secured to prevent any leaks during the process.

Step 5: Repeat The Process With Water For Rinsing

After backflushing with the cleaning agent, it is essential to rinse the machine thoroughly. Remove the blind filter and clean it under running water to remove any remaining traces of cleaner. Replace the blind filter with a clean one, without any cleaning agent, and repeat the backflushing process using water only. This helps ensure that no residual cleaner is left in the system.

Step 6: Clean And Reassemble The Group Head Components

Once you have completed the backflushing and rinsing process, it’s time to clean and reassemble the group head components. Use a group head brush to clean the group head and gasket, removing any remaining oils or residue. Wipe down the portafilter, tamper, and other accessories with a damp cloth or towel.

Step 7: Perform Regular Cleaning And Maintenance

Backflushing is just one part of maintaining your Breville Barista Express. It is important to establish a regular cleaning and maintenance routine for the machine. This includes daily cleaning of the portafilter, removing and cleaning the shower screen, descaling the machine periodically, and replacing worn-out gaskets and seals when necessary. Regular maintenance will help prevent issues and ensure consistently good coffee.

Proper Maintenance And Cleaning Tips

In addition to backflushing, following these proper maintenance and cleaning tips will help keep your Breville Barista Express in excellent condition:

  1. Clean the portafilter and baskets daily: After each use, remove the coffee grounds from the portafilter and rinse it with warm water. Use a small brush to clean the baskets to remove any residual coffee oils. This prevents build-up and helps maintain the quality of your espresso.

  2. Clean the shower screen regularly: Over time, the shower screen can become clogged with coffee residue. Remove the shower screen and clean it using warm water and a small brush or toothbrush. Ensure it is free from any accumulated coffee oils or blockages.

  3. Descale the machine periodically: The Barista Express has a built-in descaling cycle. Follow the instructions provided by Breville to descale the machine regularly. Descaling helps remove mineral deposits that can affect the taste and performance of your espresso.

  4. Replace gaskets and seals when needed: The group head gasket and seals can wear out over time, leading to leaks and poor espresso extraction. Regularly inspect these components and replace them when necessary. Refer to the user manual or consult a professional for guidance on replacing gaskets and seals.
