Inspect and Clean the Portafilter and Shower Screen
- Remove the portafilter and disassemble the filter basket.
- Use a brush and warm water to scrub away coffee oils and residues.
- Check the shower screen for clogs or buildup; clean thoroughly.
- Reassemble and reattach the portafilter.
Verify Grind Size and Coffee Dose
Ensure you are using the right grind size—finer than drip coffee but not too fine to clog the filter. Use approximately 19 grams of coffee in the 54mm portafilter for optimal extraction. Adjust grind and dose if pressure remains low.
Perform a Backflush or Descale
Use manufacturer-recommended cleaning tablets, such as the Breville BEC250 or the Replacement Espresso Cleaning Tablet, to clean internal components and remove coffee oils that can cause pressure issues. Follow the instructions on the cleaning tablets for proper use.
Check for Leaks and Worn Seals
Inspect the seals around the portafilter and water reservoir. Worn or damaged seals can cause pressure drops. Replace any faulty seals or gaskets to restore proper pressure.
