i can turn the boiler off, and it still fires up for a time, but im getting hot radiators and when i turn a tap on the flame only lasts a few seconds and then cuts out. any ideas
This boiler has a pre-heat for the hot water, thats why it fires up by itself. It sounds like your diverter valve is playing up, it may need a new referb kit, or the motor may not be working. Also if its cutting out on hot water you may have a problem with the flow switch.
