Ferroli Maxima 35 C combi boiler: F5 error?

The F5 error points to the fan assembly. I could reset it and get it working intermittently but eventually I bought a replacement fan (at £155!) and installed it. Guess what---F5! I can still get it to reset for periods but the Ferroli technical helpline says it might be the cable connections between the software and the fan. Has anyone come across this?

It is either the fan.the wiring harness.the digital display pcb or the pcb attached to tbe gas valve.do a continuity chech on the harness.

very simple, the water pressure measure unit is broken. It's located at the middle left, with a simple 3-pins connector and screwed in the water tube. Replace it with a new one (80 Euro) and it's ok.
