Boiler now about 5 yr old.
Hot water system works Ok on its own.
Since starting to use CH, it fires and runs OK for about 45 minutes before cuts out and the lockout Led lights. If left for about 90 mins, c/h will operate again. Hot water only will operate again straight away.
Radiators seem to be getting too hot.
Does this sound like the C/H thermistor is faulty?
Also was getting quite a bit of pcb relay clicking - this has stopped since moving the thermistor slightly.
