First-time Use:

Check if coffee powder quantity is too little. Add more coffee grinds to the portafilter and tamp.
Ensure coffee powder is not too coarse. Change to a finer grind.
Make sure coffee powder is pressed tightly enough. Tamp the coffee grinds with more force (around 10 - 15kg of pressure).

After Multiple Uses:

Possibility A: Inappropriate coffee making methods, such as too little coffee grinds, too coarse coffee grinds, or too little tamping force.
- Add more coffee grinds to the portafilter and tamp.
- Change to a finer grind.
- Tamp the coffee grinds with more force (around 10 - 15kg of pressure).
Possibility B: The limescale clogged the pressure gauge. Need a deep descaling. Refer to the "Descaling Cycle" section of "9.1 Cleaning & Maintenance - Brewer" on page 32.
