Weird problem!
Ariston combi boiler
When the CH dial/knob is turned down to a lower setting, when CH or DHW are then turned on, the boiler shortly cuts out (overheat stat requires resetting)
BUT
When CH dial/knob is turned up to a higher setting they both work OK!!
Is this normal or is there a fault? I am just confused, have been trying to figure out why this is happening, and ideas please?
