Our Radiant Boiler is flashing number 1 in the LCD diaplay, all instructions say what to do when light is constant but gives us no information to solve the problem when it flashes(once per second)? when we turned it off then on again the number 2 came on. the warning light is lit, it does fire then dies when we switch it on and off.

my radiant combi boiler reaches it thermostat temperature and operates for about one hour with no probs. but when it trys to reignite it comes on for a split second and then trys to keep reingniting. After about 20 atemps the boiler finally reignites. Sometimes the red cut of warning light comes on and you have to press it to reativate the boiler......Any Ideas
