My Boiler Playing Up Again - What is the problem.

Butterfliesarepretty

Green light flashes, amber light does not come on, no lighting of the pilot light. Boiler ten years old. It did this in winter a few times, its an intermittent fault.

Put shower on same thing happens. Says warm start operation but you cant hear the boiler trying to light just lots of rushing air as if the computer board is not telling the boiler to light.

Please advise and watch my video. Turn the sound up.

the 3 most common vaillant problems are the diverter valve, the pump, and the APS.
my money is on the APS.

The divertor valve was replaced in 2009 second time. What is APS. Is it the air pressure switches??? One in the top and one in the bottom??
