Step 2: Inspect the Pump and Water Path
- Listen for the pump noise when turning on the machine. A weak or no sound may indicate a faulty pump.
- Check if the water reservoir is full and seated properly. Remove and refill if necessary.
- Ensure the water flow path isn’t blocked by debris or mineral build-up, replacing filters if clogged.
Step 3: Clean and Descale the Machine
Use descaling solutions following the manufacturer’s instructions to remove mineral deposits that can affect pressure. Regularly run cleaning tablets like the Breville BEC250 or the compatible replacement tablets to maintain internal cleanliness.
Step 4: Test and Adjust Settings
Ensure the machine is properly assembled. Check if the portafilter is packed correctly and not overfilled. Verify that the grind size is suitable—finer grinds increase pressure. Run a test extraction to see if pressure is restored.
Tips and Warnings
- Always unplug the machine before disassembling or cleaning to avoid electrical hazards.
- Use only manufacturer-approved cleaning products to prevent damage.
- Be cautious when handling hot components during cleaning or inspection.
- If pressure issues persist after these steps, contact Breville customer support for professional repair.
