Have an 8 year old Ideal Slimline Classic FF350.
Normally when the boiler fires up you hear the fan start and then you hear the clicking of a relay (ignition ?). Then you hear the burner light and all is ok.
Sometimes however the boiler seems to go through a cycle where the pilot lights, then you hear the clicking and the gas valve opens and the main burner switches on. However the main burner goes out immediately and then the lighting sequence restarts. You can sometimes see the main burner firing up many times (ON,OFF,ON,OFF etc.) before it will actually stay alight.
Any advice welcome.
