Step 2: Clean the Portafilter and Shower Screen
- Remove the portafilter and soak it in warm water mixed with a cleaning tablet such as the Breville BEC250 or the Replacement Espresso Cleaning Tablet.
- Use a soft brush to gently scrub any coffee residue on the shower screen and portafilter.
- Reassemble and run a cleaning cycle if your machine has one, or run hot water through the machine without coffee to flush out any debris.
Step 3: Check and Replace Water Filters
If your machine uses charcoal or water filters, inspect them for buildup or clogging. Replace with fresh filters like the Breville Charcoal Filters or Possiave Water Filters to ensure water flows freely and pressure is maintained.
Step 4: Descale and Clear Blockages
If you notice a reduction in pressure, descaling may be necessary. Use a descaling solution compatible with your machine or the recommended cleaning tablets. Follow the manufacturer’s instructions carefully to remove mineral deposits that can impede water flow.
Step 5: Inspect Internal Components for Wear or Damage
Look for worn gaskets, seals, or valves that may be causing leaks or pressure drops. If you identify damaged parts, replace them with compatible components or consider professional servicing.
