Hi. Bit of a strange on. On Saturday my heating came on but was not asked for. Turned it off and thought no more. Sunday morning no hot water. Power light on switch is on every thing else is dead. There is no output from the board to burner live. Am I right in thinking it's possibly the pcb gone. I found the flow switch has been leaking causing steam/condensation in side the box. Could this have caused damage. Boiler is 12 years old and not internally in great condition.
Thank you for reading. Any help or ideas please.
