Boiler (3years old) will run normally until end of it,s cycle or if temp is reached. It will then over heat. When heating and hot water trips out, takes about 15 seconds for flame light to go out by which time it has overheated. Fan does not go off. Runs 24hours! Plumbers replaced thermoststat and PCB. Error code two T's horrizontal other is not in the book. Are these boilers normally this bad?

worcester boilers are the best in my opinion, i would contact worcester bosch direct and get them to do a fixed price repair, if the problem is system and not boiler related they will diagnose and probably not charge, if it is boiler faults they will offer a reasonable price and warranty on the repair, they have all the parts on the van and you wont get the run arround and delay you can expect from british gas
