Key Takeaways
| Check for blockages | Clogged filters or baskets can cause pressure issues. |
| Inspect the water system | Old charcoal filters or mineral buildup can reduce pressure. |
| Clean the group head | Residue buildup affects proper water flow. |
| Verify the grind and tamp | Incorrect grind size or tamping can lead to no pressure. |
| Ensure proper machine setup | Make sure all components are correctly assembled. |
Step 1: Check and Clean the Filter Basket
- Remove the portafilter from the machine.
- Take out the filter basket and inspect for coffee grounds or blockages.
- Rinse thoroughly under warm water to remove oils and residues.
- If clogged, use a brush to gently clean the holes.
Step 2: Inspect and Replace Water Filters
Old or clogged water filters can hinder pressure. Remove the existing charcoal filter and replace it with a new one, such as the Breville Charcoal Filters (asin=B000VX44OO) or Possiave Water Filters (asin=B089R7ZRBG).
Step 3: Clean the Group Head and Shower Screen
- Turn off the machine and allow it to cool.
- Remove the portafilter and wipe the shower screen with a damp cloth.
- Use a cleaning brush to remove coffee residues from the screen and surrounding area.
- Reassemble once clean and dry.
Step 4: Check Coffee Grind and Tamping Pressure
Ensure you’re using the correct grind size—fine but not powdery—and tamp with even pressure. Too fine or overly tamped coffee can prevent proper water flow and pressure buildup.
Additional Tips and Precautions
- Regularly descale your machine to remove mineral buildup.
- Always use fresh water and change filters every 2 months.
- Avoid forcing components together if they don’t fit easily.
- Consult the user manual for specific cleaning instructions.
