I have a Worcester/Bosch 350 Combi. The CH 'Low Pressure' light is illuminated. Having followed the troubleshooting tips from other posts on this site I have checked the expansion vessel air pressure. I have drained the CH system water via a radiator. I have no air pressure in the expansion vessel and after removing the pressure gauge, water is dripping from the valve.
I believe this means that the expansion vessel membrane is ruptured. Please can you confirm my diagnosis, and if correct, how difficult is it to change the expansion vessel. Is it a job for a pro ?
Is it possible to repressurize the system enough to get the hot water back on pending the expansion vessel change ? We can live without the heating for a while but we are beginning to smell a bit !!! Thanks
