ok got the difinitive answer now so anybody in future will know.
the PCB covers 2 models, HE31C and the HE31C plus. for the HE 31C to run correctly there is a parameter that needs to be changed. phone the ferroli tech helpline and they will talk you through it.

ok if you take the plug off the pressure sensor and bridge out the first and the last wire positions on the plug with some wire then switch the boiler on. if it fires up ok then you need to replace the sensor.i did this last night pick up new sensor today from PTS.( DONT KNOW IF THE THE BOARD GOING BLEW THE SENSOR OR VISA VERSA)
