Hi, just wanted to say that I actually fixed the issue by cleaning the pressure sensor as suggested here:

Since I have the short 40 cm dishwasher, down there is more compact and locate and detach the sensor is not an easy job.
There are some videos on internet but refer to bigger models.
I actually disconnected and reconnected it by using my hand from both sides, back and front, and without looking at the part, just feeling it.
Anyway, I removed some dirt from it and now the dishwasher has run twice without a problem.
Thank you everyone 🙂
