Step 2: Check and Clean the Water Filter
- Remove the water reservoir and inspect the charcoal filter for debris or clogging.
- If dirty, replace with a new filter or clean if applicable.
- Reinsert the filter securely and fill the reservoir with fresh, filtered water.
Step 3: Inspect the Portafilter and Coffee Grounds
- Ensure your coffee grounds are tamped evenly and firmly—too loose can cause low pressure.
- Check that the portafilter is clean and free of old coffee residues.
- Make sure the portafilter is properly seated in the group head.
Step 4: Clean the Machine’s Water Pathways
- Use a cleaning tablet designed for Breville machines, such as the Breville BEC250 or BWF100, following the manufacturer’s instructions.
- This will remove mineral scale, coffee oils, and residues that can block water flow.
Step 5: Descale the Machine Regularly
Mineral buildup can significantly impact pressure. Use descaling tablets or solutions periodically—every 1-3 months depending on water hardness—to keep your machine functioning optimally.
