Step 2: Check the Water Reservoir and Filters
- Remove the water reservoir and inspect for any blockages or debris.
- Replace or clean the charcoal water filters if they are old or clogged, as these can restrict water flow and pressure.
- Ensure the water reservoir is seated correctly before restarting.
Step 3: Clear Clogs in the Shower Screen and Filter Basket
- Remove the portafilter and inspect the shower screen and filter basket for coffee grounds or residues.
- Use a soft brush or pin to gently clear any blockages.
- Run hot water through the shower screen to flush out any buildup.
Step 4: Descale the Machine if Needed
If you notice mineral buildup or scale, it can impede water flow. Use appropriate descaling tablets such as the Breville BEC250 or the Replacement Espresso Cleaning Tablets. Follow the manufacturer’s instructions to descale your machine regularly.
Step 5: Check the Coffee Tamp and Grind Size
- Ensure you are tamping evenly with appropriate pressure—about 30 pounds of force.
- Use a consistent grind size, typically medium-fine, to optimize pressure buildup during extraction.
- Avoid overfilling or underfilling the filter basket.
