after 2 weeks of changing pumps 3way valves and temp sensors a man said it may be your pcb board but if you fit a new one you will have to change the parameter settings to match your boiler. so i rung ferroli support on 08715592927 to find out how to do it . after pressing reset and mode 2 or 3 times the boiler reset and has run ok .so i saved 160 quid on a pcb board and the boiler works fine thanks to ferroli support
