I have a Vaillant Combination boiler model PLUS824E. At the moment there is no hot water or central heating. The boiler display shows 25 degrees and the green light flashes constantly. When I switch the central heating on the boiler does not respond, when the tap is turned on the boiler starts but the temperature doesn't rise on the boiler display.
This appears to be an intermittent fault as it happened a few weeks ago and by the time the plumber arrived it was working again. He advised that until he sees it not working he is unsure of what is causing the problem and doesn't want to replace expensive parts hoping that it might fix the problem. Has anybody experienced something similar with this model of Vaillant Boiler.
