Step 2: Clean the Shower Screen and Portafilter
- Remove the portafilter and soak it in warm water with a cleaning tablet or mild detergent.
- Wipe the shower screen with a soft brush or cloth to remove coffee residues and oils.
- Reassemble and run a blank shot to see if pressure improves.
Step 3: Check and Replace Water Filters if Needed
If your machine has a water filter (like Breville Charcoal Filters), inspect it for clogs or buildup. Replace it if it’s overdue or visibly dirty, as a clogged filter can restrict water flow and pressure.
Step 4: Descale the Machine
Mineral buildup can impair water flow and pressure. Use a descaling solution or descaling tablets designed for Breville machines. Follow the manufacturer’s instructions for descaling to clear any mineral deposits from internal pipes and the pump.
Step 5: Test the Pump and Internal Components
If cleaning and descaling do not resolve the issue, listen for the pump sounds during operation. If the pump is silent or weak, it may need professional repair or replacement. Do not attempt to disassemble the pump yourself, as it involves delicate parts.
