Check the Water Filter and Water Level
- Ensure the water filter is properly installed and not clogged. Replace if necessary, using compatible charcoal filters like the Breville Charcoal Filters.
- Verify the water reservoir is filled to the appropriate level. Low water levels can cause low pressure during extraction.

Clean the Portafilter and Shower Screen
- Remove the portafilter and clean it thoroughly, removing any coffee grounds or oils.
- Detach the shower screen and clean it with a soft brush or cloth to remove residues that block water flow.
Descale and Use Cleaning Tablets
If mineral buildup is suspected, descale your machine following the manufacturer’s instructions. Use Breville BEC250 Cleaning Tablets or the Replacement Espresso Cleaning Tablet for thorough cleaning, which can help restore proper pressure.
Inspect Seals and Gaskets
- Check the seals and gaskets around the portafilter and internal components for wear or damage.
- Replace any worn gaskets to ensure a tight seal, which is crucial for maintaining pressure.
Run a Test and Final Check
After cleaning and reassembling, run a test shot. Observe if the pressure builds up properly. If issues persist, consult a technician or contact Breville customer support.
