4.1 General

characteristics

The EWM10931 electronic control system consists of two circuit boards plus the motor control system (inverter).

The control / display circuit board, inserted in a plastic
box, secured to the control panel.

The figure shows:

The control / display circuit board and plastic container
already assembled.

The display board.

The side header that the selector is fitted to.

The flat cable that connects the 2 circuit boards to one
another.

The main board is positioned to the rear of the equipment and receives commands from the display board and
signals from various sensors located in the washing machine, powers the electric parts and communicates with
the motor control board (Inverter).
