5.1 General characteristics

The EWM09312 / EWX13611 / EWX14931 electronic control system consists of two circuit boards plus the
motor control (Inverter) for washing machines.
In the event of problems with the touch sensors (difficulty selecting/adjusting them), clean and dry the display
and do not wear gloves when setting the chosen programme.
 The control/display circuit board, inserted in a plastic box, secured to the control panel (the figure illustrates:
the display circuit board with the side support plate onto which the selector is secured, connected to one
another by a flat cable and the display circuit board assembly).
 Main board, positioned in the bottom rear of the appliance. It powers the electrical components and
receives commands from the display board as well as for EWX14931 communicating with the motor
control board (Inverter UIMC).
