My Vokera compact 29He boiler has just started to have a fault. when the boiler is switched on the green light flashes, everthing seems to be starting up correctly; fan, seems to "strike" up etc, but after a few seconds the boiler shuts down and a red light comes on the front panel??
Thanks in advance, Steve

Same problem here... have tried re-pressurising but same thing happens. Last time I had this problem plumber changed the fan.
