Key Takeaways
| Check for clogs | Clogged filters or shower screens reduce pressure. |
| Adjust grind size | Too fine or coarse grinding affects flow. |
| Maintain cleanliness | Regular cleaning prevents blockages and scale. |
| Inspect water filters | Impurities or clogged filters can impact pressure. |
Step 1: Turn Off and Unplug Your Machine
Before inspecting or cleaning, ensure the espresso machine is turned off and unplugged to prevent electrical hazards.
Step 2: Check and Clean the Shower Screen & Portafilter
- Remove the portafilter from the group head.
- Inspect the shower screen for coffee oil or residue buildup.
- Soak the shower screen and portafilter in warm water with a cleaning tablet or mild detergent.
- Use a soft brush to gently scrub away any blockage.
- Reassemble and run a blank shot to see if pressure improves.
Step 3: Verify Grind Size and Dose
- Adjust your grinder to a slightly coarser setting if the coffee is too fine, which can cause slow flow or no pressure.
- Ensure you’re using approximately 19 grams of coffee in the 54mm porta-filter for optimal extraction.
Step 4: Check and Replace Water Filters
- Remove the water reservoir and inspect the charcoal filters for buildup or clogging.
- If using a Breville Charcoal Filter or Possiave filter, replace them every 2 months or as needed.
- Install the new filter properly, then run hot water through the machine to flush out residual impurities.
Step 5: Descale and Clean Internal Components
If scaling is suspected, use a descaling solution or cleaning tablets designed for Breville machines. Follow the manufacturer instructions for descaling frequency and procedure to ensure optimal pressure and performance.
