Step 2: Check and Clean the Shower Screen and Filter Basket
- Remove the portafilter and inspect the shower screen for coffee grounds or oil buildup.
- Use a pin or a brush to gently clear any blockages.
- Soak the portafilter and shower screen in warm water with cleaning tablets or descaling solution for 15-20 minutes.
Step 3: Inspect the Coffee Grounds and Tamping Technique

- A too-fine grind or over-tamping can cause backpressure issues.
Step 4: Check Water Filters and Water Line
Replace any clogged Charcoal Filters or water filters, such as the Breville Charcoal Filters or Possiave Water Filters, every 1-2 months. Ensure the water reservoir is filled with fresh, clean water.
Step 5: Run a Cleaning Cycle
Use specially designed cleaning tablets, like the Breville BEC250 or Replacement Espresso Cleaning Tablets, to descale the machine. Follow the manufacturer’s instructions to run a cleaning cycle and remove mineral buildup that can impede pressure.
