Hi, We had the boiler installed 2yrs ago this month. Recently intermittently the water started to run cold. checking the boiler the flashing neon light is on the 50C neon. I see that this is a fan or flue problem . Phoned baxi up and explained , they said i was only covered for 1 yr ...+3 free month as i had registered with them . Explained only had less than 2 yrs . They have let me take cover out for it but i cant get an engineer until 27 days now . The boiler wont work at all now ...starts up but after about 30 secs , light starts #tarts flashing again . CH wont also work ...Any idea how much this would cost from experience as my mother has offered to pay for someone to come out in the meantime as I don't want me mother stung with a big bill, only its freezing in the house and we have 2 young kids and receive working tax credits .....please can anyone suggest something ....I have since been told I may have been able to have a boiler installed for free due to the working tax credits etc from warmfront . any help greatly appreciated ..alan
