Hello Guys,
I need help fast please, l have a baby in the house and my boiler won't work. I bled my Vaillant VCW-Sine 18 T3WF H Combi Boiler and added a Fernox cleaning solution through one of the radiators but now it will not work i.e. no hot water and no heating. The flame is on and all seem well but it makes an awkward high pitch noice when turned on......what should l do?
