Clean the Machine
Use specially designed cleaning tablets, such as Breville BEC250 Espresso Machine Cleaning Tablets, to dissolve coffee oils and residues. Follow the manufacturer’s instructions for descaling and cleaning to ensure optimal performance.

Inspect Internal Seals and Gaskets
Open the machine according to the user manual and examine seals and gaskets for wear or damage. Replace any worn parts to prevent leaks that cause pressure drops.
Test and Reassemble
- Reassemble the machine carefully, ensuring all parts are correctly fitted.
- Run a test shot to see if pressure improves. If not, repeat inspection or seek professional repair.
