I'm really hoping someone can help me. Over the past few days my central heating in on constantly. My thermostat is fine and showing that the heating doesn't need to be on yet the boiler displays 'c' and the burner light keeps flashing. I can only stop it by switching the boiler off. I'm not getting a fault code and my dhw is absolutely fine. The diverter valve was replaced just over 3 years ago. Is it likely to be that again or could it be something else?
Any helpful suggestions would be appreciated. Thought I would try on here first if I can save the expense of having an engineer called out!!
