I have a heatline solaris 34pc/30pc condesing boiler which is showing a F9 fault which means - fan is moing, if fan must be stopped. In the manual it says check cleaning of fan. Does anyone know how i can do this please? just check price for replacement and its £142, so hoping the cleaning bit works. Any answers would be appreciated.
regards Jason
