Hi, I am after some advise on my Ferroli 102 boiler, basically its going into "lock out" but only in the morning after a night of rest. I will have to reset the switch maybe 20 times before it runs. This is for CH or DHW. I have drained down and cleaned the flow switch out, then decided to replace, I have also replaced the pcb (as I had a spare). The flu is intact and leak free. What happens is, you turn it on for heating or demand HW and the flame lights, then after 4-5secs it lock out. As I said, once running after endless resets, its fine all day. One thing I have noticed, is that, rather than turning the heating off on the boiler front panel manually at night before bed to prevent it running at night, If I was to turn the temp control to 0, but leave the boiler "on" so to speak, then in the morning if I wanted to turn the heating on I just turn the dial to turn temp up it often works, could this be the gas valve? if so how do they fail?
