In case of burning on the main circuit board, check
that the problem is not caused by another electrical component (short-circuits,
poor insulation, water leakage).
Refer to the figures below in order to identify the
component that might have caused the burning according to the
position of the burned area.
The circuit board shown below is the version with the greatest
number of components: other boards may not feature all these
components (relay K4 and buzzer).
