This section provides a list of the most common burner and boiler failures.
Burner error code
We have already mentioned that the burner is equipped with a cut-out system, indicated by the reset
button light. It may cut out accidentally, and in this case the steady red light on this button will come
on. You may unblock it by pressing the button for approx. 1 second. When the burner is blocked and
the steady red light is on, visual failure diagnosis may be activated, in accordance with the error code
table. To enter visual failure diagnosis mode, hold down the reset button for at least three seconds.
