Step 2: Check for Blockages in Ports and Filters
- Remove the portafilter and inspect the shower screen and filter basket for coffee grounds or oils that might be clogging the flow.
- Use a pin or a small brush to clear any debris from the holes in the shower screen.
- Check the water outlet and steam wand for blockages and clear them carefully.
Step 3: Clean and Descale the Machine
Regular cleaning prevents scale buildup that can affect pressure. Use Breville BEC250 Espresso Machine Cleaning Tablets or a suitable descaling solution. Run a cleaning cycle following the manufacturer’s instructions to remove oils and mineral deposits.
Step 4: Inspect and Replace Worn Seals
Check the group head gasket and other rubber seals for cracks or wear. Worn seals can cause pressure leaks. Replace any damaged gaskets with compatible parts to restore proper pressure.
Step 5: Test the Machine
After cleaning and replacing any worn parts, reassemble the machine, fill the water tank, and run a test brew. Observe if the pressure now reaches the optimal level during extraction.
