Next, below is a written step-by-step process for adjusting the brew pressure:

Why is the machine not showing the right pressure?
The first step is to put the blind portafilter in, activate the brew switch, and see if the pressure gauge reads anything. From there, adjust the OPV per the manual to read 9 bar. If there is no pressure with the blind portafilter in and the OPV adjusted, there is a problem, please contact us. If it shows pressure, the machine is working as designed, please contact us if you have further questions.

How do I set the pressure on my machine?
That is quick and easy! Please follow these steps to set the pressure on your machine properly:

1) Turn the machine on, and let it reach full operating temperature
2) With the blank (cleaning) basket in the portafilter, lock the handle in the machine.
3) Locate the OPV adjustment screw to the left of the group head
4) Engage the group by holding the brew switch up or down. After 3 to 5 seconds, the pressure gauge should stop at the set pressure
5) Adjust the OPV screw until that needle points to 11, then release the brew switch
6) Press and hold the brew switch again to verify that the setting is at 11. Repeat steps 4 and 5 if further adjustment is needed.
7) Once the above is done, the pressure on your machine is set. You will want to adjust your grind, dose, and tamp to achieve 9 BAR during extraction.
