Sticking diverter valve
Posted on Jun 28, 2009
The heat is obviously not getting away from the boiler due to either a blockage or more likely a closed valve. check that the flow and return valves are opened as some people accidently turn the return off when putting pressure in the boiler. if these are open then it is likely that the diverter valve is sticking. you can sometimes get them going temporarily by stripping them down or a persuasive tap on the motor but will stick again. will need replacing if this is the case. i can get hold of the diverters if you require one so post a reply if you do and i will give you my details.
