2. Check and Clean the Portafilter and Filter Basket
- Remove the portafilter from the machine.
- Disassemble the filter basket and rinse all parts thoroughly with warm water.

3. Clean the Shower Screen and Nozzle
- Remove the shower screen (consult your user manual if needed).
- Soak in a descaling solution or warm vinegar solution for 15 minutes.
- Use a toothbrush to scrub away any coffee residue.
4. Check and Replace the Water Filter
Old or clogged water filters can restrict flow and pressure. Replace your Breville Charcoal Filter (asin=B000VX44OO) or compatible filters as needed. Ensure the filter is properly seated in the water reservoir.
5. Verify Grind Size and Dose
Use a consistent grind size—ideally medium-fine for espresso—and dose about 19 grams into the portafilter. Too coarse grind or underdosing can cause low pressure and weak extraction.

Frequently Asked Questions
Why does my espresso machine have no pressure?
Low or no pressure can be caused by clogged filters, dirty shower screens, incorrect grind size, or a blocked water flow. Regular cleaning and maintenance are essential.
How often should I clean my Breville Bambino Plus?
It’s recommended to clean the shower screen and filter basket weekly, and use cleaning tablets like Breville BEC250 every 1-2 months to keep internal parts free of oils and residues.
Can a water filter cause pressure issues?
Yes, a clogged or old water filter can restrict water flow, leading to low pressure. Replacing it with a compatible charcoal filter helps maintain optimal pressure.
