How do i fix my worcester bosch 30cdi combi boiler?
Had new boiler installed 4mnths ago and today it started making strange noises. (pressure display within the blue marker) A few minutes later "EA" flased on the display. Turned off and restarted with no joy- boiler starts to reheat but the same happens. Any advice as to what to do next. What does "EA" mean?
I have exactley the same problem. Solution pour hot not boiling water on the condensing pipe - the pipe outside leading into the ground.
