Hi can anyone help me please? i have a British gas 330 boiler installed in 2005 and it has stopped working. It is showing fault code f 10, when i try to reset it by switching it off and on there is a whirling noise from what sounds like a fan or motor only for a couple of seconds then it dies down and fault code f 10 reappears, can anyone help me please as this quite a needy time for the heating, many thanks
