Step 2: Check and Clean the Portafilter and Filter Basket
- Remove the portafilter from the machine and empty any used coffee grounds.
- Wash the filter basket and portafilter thoroughly with warm water to remove oils and residues.
- Reassemble and ensure they are seated properly.
Step 3: Inspect and Clean the Water Filter
If your machine uses a water filter (see product features), remove it and soak in warm water with a cleaning tablet like the Breville BEC250 or B000VX44OO to remove scale or impurities that may restrict flow. Replace the filter if it’s old or clogged.
Step 4: Check for Blockages in Water Path
- Remove the water reservoir and inspect the opening for debris or scale buildup.
- Use a soft brush or cloth to clean the reservoir and water outlet.
- If your machine has a cleaning cycle, run it to clear internal lines.
Step 5: Adjust Grind Size and Dose
Ensure your coffee grind is fine enough for espresso. Coarse grounds can cause low pressure. Use the dose control to load approximately 19 grams into the portafilter, tamp evenly, and try brewing again.
