Step 2: Check and Clean the Portafilter and Shower Screen
- Remove the portafilter from the machine and empty any remaining coffee grounds.
- Use a brush to clean the shower screen and the portafilter’s holes thoroughly.
- Ensure the portafilter gasket is intact and seated properly.

Step 4: Check Water Filter and Water Reservoir
- Remove the water filter (if installed) and inspect it for clogs or buildup. Replace if necessary.
- Refill the water reservoir and ensure it’s properly seated.
Step 5: Inspect Internal Components and Seals
Look for worn or damaged seals inside the machine, especially around the group head and portafilter. Replace any faulty seals to restore proper pressure.
