7.1  EDW503 Electronic control system  

 

The EDW503 control system consists of a main circuit board and a control/display board. Both 

boards are housed in a plastic container (fig. 1). The On/Off function is performed by the button

7.1.1  Functions of the circuit board 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

The circuit board receives signals relative to the cycle settings via the control/display board. The buttons 
and LEDs are also mounted on this board. 

 

The board also powers all the electrical components (solenoid valves, washing pump, detergent/rinse-
aid dispenser, drain pump, heating element) 

 

The board controls the temperature of the washing water via an NTC sensor 

 

The circuit board monitors the status of the pressure switch and the rinse-aid/salt sensors.
