I have a Worcester RD532i boiler, recently the digital screen started flasing FC, the boiler does not seem to be getting information from thermastat on wall, tried changing three fuses that are visible but still does not work, other screen on boiler just keeps saying please wait initializing. can anybody shed any light on the matter, I would be most grateful.
