Why did the fumes NTC trip due to overtemperature in my Westen Boyler Condens 24?

If your Westen Boiler indicates 'Fumes NTC tripped due to overtemperature', check the heat exchange of the water/fumes exchanger for insufficient circulation or the presence of scale. Also, check the fumes NTC probe.
