If your Breville Bambino Plus is delivering no pressure during extraction, it can result in weak or espresso-free shots. This issue often stems from clogs, scale buildup, or pressure system faults. Before calling a technician, try these practical troubleshooting steps to restore pressure and get back to enjoying cafe-quality coffee at home.
Safety first: always unplug your machine before performing any maintenance or cleaning. Follow each step carefully to avoid damage or injury.

| Inspect the water filter | Clogged filters can restrict water flow and pressure. |
| Ensure proper grind size | Too coarse grind prevents proper pressure buildup. |

Step 2: Check for Blockages in the Portafilter and Shower Screen
- Remove the portafilter and inspect the filter basket for coffee grounds or blockages.
- Clean the shower screen by removing it and soaking it in hot water with your cleaning tablets or descaling solution.
- Use a soft brush to clear any debris from the shower screen and portafilter holes.
Step 3: Clean and Descale the Machine
- Run a descaling cycle using a Breville-approved descaling solution or the recommended cleaning tablets.
- Follow the manufacturer’s instructions for descaling to remove mineral buildup that can impede pressure.
Step 4: Check the Water Filter
If your machine uses a water filter, remove and inspect it for clogs or buildup. Replace with a new filter if necessary, following the instructions specific to your model.
Step 5: Verify the Grind Size and Dose
Ensure your coffee grind is appropriately fine for espresso. Too coarse grind can cause low pressure. Use about 19 grams of coffee in the 54mm portafilter for optimal results.
Step 6: Test the Pump and Pressure System
If pressure issues persist, listen for the pump operation when turning on the machine. A failing pump may require professional repair or replacement.
