Inspect and Replace Worn Seals or Gaskets

Worn or damaged seals can cause pressure leaks. Carefully examine the group head gasket and portafilter seals for cracks or deterioration. If you notice any damage, replace the seals with genuine Breville parts to restore proper pressure and prevent leaks.

Clean the Machine with Proper Maintenance Products

  • Use Breville BEC250 Espresso Machine Cleaning Tablets to remove coffee oils and residues that can hinder pressure.
  • Follow the manufacturer’s instructions for cleaning cycles, typically involving dissolving tablets in water and running a cleaning brew.
  • Replace water filters regularly using compatible charcoal filters to prevent mineral buildup that affects pressure.

Descale Your Espresso Machine

Mineral deposits can cause pressure issues. Use a descaling solution suitable for Breville machines, and follow the descaling instructions provided in your user manual. Regular descaling helps maintain consistent pressure and prolongs the life of your machine.

Test and Final Adjustments

After cleaning and replacing worn parts, run a test shot. Observe the pressure gauge and extraction process. If pressure still drops, repeat the inspection for blockages or leaks. Persistent issues may require professional repair or contacting Breville support.
