My Baxi Solo 40/4 wall mounted boiler stopped 2 days ago,the pilot light went out,, I re-lit and the burner flame ignited all was well..today its done the same. I can re-light the pilot no problem but when it calls for the burner flame for heat it clicks and switches off again.problem started when the snow came. Is it a case of re-setting something or calling a professional.
sounds to me like your gas valve is playing up, i assume your boiler flue didnt get full of snow? i also assume your pump is working ok if your boiler has a fan is it running, in any case it sounds like an engineers job good luck
