Step 2: Check and Clean the Shower Screen and Group Head
- Remove the portafilter and detach the shower screen (if removable).
- Soak the shower screen and filter basket in warm water with a bit of espresso machine cleaning tablet or descaling solution.
- Use a soft brush to remove coffee residues and mineral buildup.
- Reassemble and run a cleaning cycle with water to clear out loosened debris.
Step 3: Inspect the Water Reservoir and Charcoal Filter
Ensure the water reservoir is filled properly and the charcoal filter (if installed) is not clogged. Replace the filter if it appears dirty or is past its recommended change interval.
Step 4: Check for Blockages in the Pump and Pipes
Listen for unusual sounds from the pump during operation. If the pump is silent or weak, it may be blocked or failing. Consider descaling the machine using a suitable cleaning tablet like the Breville BEC250 or Replacement Espresso Cleaning Tablet to remove mineral buildup.
Step 5: Verify Coffee Grind and Tamping Pressure
Use a fine, consistent grind and tamp the coffee evenly. An improper grind can cause low pressure during extraction. Adjust your grind size and tamp pressure accordingly.
