It's a very common question, so we give you some possible solutions for that.
Possible faults:
- Faulty Group gasket
- Perfect crema pin is missing
- Pressurised basket is blocked (in this case please soak it oven cleaner for long hours and then try to clean it with a soft brush). Do NOT use a pin to clean your basket.
If it does not sort out the problem, you might need a new pressurised basket here >
