    Yes the red light on the board is on (but not 100%, it is giving very little light) How do I check the connection at connection strip?

    Thanks for your reply, I have checked and its not short, I have put a plastic sheet below the switch so that leaked water goes out without falling on anything inside the boiler. What else can be the cause. Really appreciate your response.

    Everytime I turn the boiler on, the green light comes on and burner starts burning automatically without any demand for heating or hot water, and then it locks out. Also few drops are dripping from DHW switch.
