What causes this fault?

This is not a mechanical failure but rather a custom setting that dictates how long the internal pump continues to circulate water after the burners have turned off. It is designed to dissipate residual heat from the heat exchanger to protect the internal components from overheating. If you see this code, it simply means the boiler is carrying out its programmed cooling cycle before coming to a complete stop.
