Heatline Combi C24 Won't Start After Being off for a Few Hours Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

My Heatline combi boiler C24 will not start after it has been off for a few hours or first thing in the morning. The green led light on the front panel is on but it is dull. If I switch off the boiler at the mains and switch it back on the green light comes on brighter. When I then turn the stat up the boiler kicks in and works fine. Sometimes the green light stays dull however and the boiler won't work. When this happens I leave it off for a while and it normally comes back on bright green enabling the boiler to kick in. I have sometimes had to take out the main Pcb and interface boards then put them back in which sorts out the problem also. It has been happening for months and I have to get up every morning to switch the boiler back on. I have posted a video on YouTube at the following link. https://youtu.be/Ty-A5BuiARY I am not sure if it's a pcb fault, an interface board fault or a fault with the thermostat or something else? My plumber/boiler man does not know either. Any help would be really appreciated. Thanks
