Very nice! I have exactly the same machine in white color from the factory. I replaced the shower screen with the E&B nanotechnology (E61200RNT) and loving the results in extraction. The only strange thing is that on the app, for instance, the boiler at 126 Celsius gives a pressure of 1.45 bar, but at the gauge, there always shows a difference of 0.15 bar lower. Is that the same with yours? Also, mine came configured with extraction pressure at 8.5bar by the gauge.
Nice! Yes, Nano tech is amazing! These mechanical guages will always show a little discrepancies, but the difference will also make very minimal change to the coffee. It is very easy to adjust to pump pressure (especially when you have a hole in the side of the machine) 😅 I would recommend dialling it in with a scace 👍
