Step 2: Check and Replace Water Filters
- Open the water reservoir and remove the charcoal filter or water filter cartridge.
- If the filter appears dirty or clogged, replace it with a new filter such as the Breville Charcoal Filters or compatible options.
- Reinstall the filter and fill the reservoir with fresh, clean water.
Step 3: Clean the Group Head and Shower Screen
- Remove the portafilter and use a brush to clean the shower screen and group head thoroughly.
- Use a cleaning tablet (like the Breville BEC250 or the Replacement Espresso Cleaning Tablet) dissolved in water to descale and remove oils inside the machine.
- Run hot water through the group head without coffee to flush out any residues.
Step 4: Check the Portafilter and Basket
Ensure the portafilter is properly fitted and the basket is clean and free of coffee grounds or blockages. Improper fitting or dirty baskets can cause pressure issues.
Step 5: Descale the Machine
Regular descaling prevents mineral build-up that impairs pressure. Follow the manufacturer’s instructions using a descaling solution or tablets specifically designed for Breville machines.
