I am getting very bad radio and tv interference when my Baxi Bermuda back boiler switches out. There is a rapid clicking noise that comes from the back boiler at the same time, almost like a solenoid sticking. Anyone any suggestions what this is and what will cure it?

this could be either the gas valve or more likely the ignition transformer (assuming it is not a pilot light type boiler) bit unusual to happen when cutting out, as both items should be off.
have you got book on boiler as there may be a circuit diagram showing a suppresser which may have failed, sorry no other ideas at the moment,Sparx
