update:my local engineer suggested we just change the thermistor initially and 'see how it goes'
he fitted this, and worked fine when he was here, been a day now and the same symptoms exist.
i dont want to change the pcb to find that this also hasnt resolved the problem.
do you think, changing the pcb will probably resolve this?, or can only be known by try and see?
the only changes ive noticed is, sometimes the boiler does not reset but the temp drops to 30c and holds there. at the same time the boiler makes a much more louder noise than normal- funnily the gas meter also has a louder noise at this same time!! (only when the boiler makes this noise though-no idea if this is linked?)
