Hi
I have a problem with the above. It keeps getting overheat lock out but only when the heating is on. Hot water is fine and the boiler has worked perfectly all year. However when the heating is switched on, it locks out within 1-2 hours.
My Gas Safety engineer has been through the fault finder and tried the relevant things but it still locks out. The only thing now is to replace the PCB. However does this seem right considering it only locks out on heating? He is stumped.
Any ideas?
