it stopped working this morning when i found the condenstate and flue both frozen with a large icycle hanging from the flue. i have thawed them out but it still wont fire, more worryingly the boiler warning light doesnt flash slow anymore but fast indicating a control board fault? help
it may still be frozen somewhere, try where the condensate pipe passes through the wall. otherwise the condensate trap may need to be cleared, that's a job for an engineer.
