8.3 Burns on the main circuit board EWM10931
In the event of burns on the main circuit board, check whether the problem was caused by another electrical component (short-circuits, poor insulation, water leaks). Use
the figures that follow to pinpoint the component which may have caused the problem, depending on the area of the burns.
The type of board illustrated is the one with the largest number of components; other boards do not feature some of these components.
