I am getting the error code 28, if i bypass the flue sensor with a bit of wire the error goes away and the boiler works, so can i assume the flue sensor if faulty? If I do a continuity on the sensor there is none, should there be? I did buy a replacement on ebay and fitted it, the code did not go away and also there is no continuity over the new sensor so would that be faulty also?
