I left my heating on my Ferroli boiler. I went to switch it off after 6 hours (I forgot to turn it off....) and could smell an electrical smell. On inspection it had turned off and wouldn't turn back on. The timer still works though. Does anyone know what might be wrong and if it sounds like an expensive job?
when turning boiler on it starts up as normal, flame ignties and stays on for 3-4 seconds then shuts down, is it something i an repair myself, thank you
