Hi again,thanks for the help but ive managed to fix it.

It was the "themister" which just needed resetting. Behind the grey facia panel theres a copper pipe on the left,this themister is located here & has 2 wires either side & a tiny switch in the centre. I pushed this switch back in & the boiler is now working fine.

Perhaps this was activated due to the low pressure causing it to overheat?? Anyhow maybe this will help someone in the future...

Thanks again,

could be the air pressure switch that tells the pcb the fan is running
