Key Takeaways

| Inspect the pressure release valve | Ensure it is functioning properly and not stuck open. |
| Verify water flow | Ensure water reservoir is full and the water intake is unobstructed. |
Step 1: Turn Off and Unplug the Machine
Before starting any repairs, turn off the espresso machine and unplug it from the power source to ensure safety during troubleshooting.
Step 2: Remove and Clean the Portafilter and Shower Screen
- Remove the portafilter and inspect for coffee grounds or blockages.
- Clean the portafilter and shower screen thoroughly with warm water and a brush.
- Reassemble once clean.
Step 3: Check and Clean the Water Reservoir and Filters
- Ensure the water reservoir is filled and seated correctly.
- Remove the water filter (if installed) and clean or replace it to prevent flow restrictions.
- Use a descaling solution periodically to remove mineral buildup.
Step 4: Test and Inspect the Pressure Release Valve
Locate the pressure release valve—usually near the group head or pressure gauge. Ensure it is not stuck open or closed. If stuck, gently clean or replace it following the manufacturer’s instructions.
Step 5: Descale the Machine
Use a descaling tablet or solution designed for Breville machines, such as the Breville BEC250 cleaning tablets, to remove scale buildup that can prevent proper pressure. Follow the descaling process outlined in your user manual.
