The pilot light for my boiler(above) went out last week. I managed to get it back on but since then the immersion(boiler) will not come back on. When I turn on the heat, it will heat the radiators but not the main boiler. I didnt change any other switches, just reset it last week. Any ideas on how to fix this or do I need to get a plumber out?
Sounds like your motorised valve for the dhw has gone faulty,
it's usually located in you hot press...
Not a boiler problem, plumer will sort it for you in no time
