Key Takeaways
| Check water filters | Clogged filters can cause pressure issues. |
| Clean the group head | Coffee oils and residues block pressure buildup. |
| Inspect the portafilter | Damaged or improperly fitted portafilters can affect pressure. |
| Examine the pump | A faulty pump may need replacement. |
| Ensure proper grind size | Too coarse grind can prevent proper pressure. |
Step 1: Turn Off and Unplug the Machine
Before starting any troubleshooting, ensure the espresso machine is turned off and unplugged from the power outlet for safety.
Step 2: Check and Replace Water Filters
- Remove the water reservoir from your Breville Bambino Plus.
- Inspect the charcoal filters (if present). If they are old or clogged, replace them with new ones like the Breville Charcoal Filters (asin=B000VX44OO) or Possiave Water Filters (asin=B089R7ZRBG).
- Reinstall the reservoir and run water through the machine without coffee to flush the system.
Step 3: Clean the Group Head and Portafilter
- Remove the portafilter and clean the filter basket thoroughly to remove coffee oils and residues.
- Use a cleaning tablet like Breville BEC250 (asin=B00494MU9M) to descale and clean the shower screen and internal parts.
- Ensure the portafilter fits snugly and that there are no cracks or damage.
Step 4: Check the Pump and Seal
If cleaning doesn’t restore pressure, inspect the pump. Listen for unusual noises or lack of sound during operation. If suspect, contact a technician for testing or replacement. Also, inspect the portafilter gasket for wear and replace if necessary.
Step 5: Adjust Grind Size and Dose
Ensure your coffee grind is fine enough for espresso. Too coarse grind prevents proper pressure buildup. Use a consistent dose—around 19 grams for the Bambino Plus—and tamp evenly. This ensures optimal extraction and pressure formation.
