1  Purpose of this manual 

 
The purpose of this manual is to provide service personnel (who already have the basic knowledge 
necessary for repairing dishwashers) with information on dishwashers equipped with the EDW500 
electronic control system, which are produced in the Solaro (MI - Italy) factory. 

The EDW1500 control system consists of a main circuit board and a control/display board. Both 

boards are housed in a single plastic container, with integrated selector. It is used in some “DIVA” models. 
 
This Manual describes: 

 General 

characteristics 

 

Control panel and programmes 

 Technical 

characteristics 

 

Guide to diagnostics  

 

For more detailed information regarding the hydraulic circuits and the structural characteristics of the 
appliances, refer to the Service Manual for presentation of the “DIVA” structure (publication number 
599 35 55–25 and 599 36 09-90). 

 

2 PRECAUTIONS 

 

 

 

 

Electrical appliances must be serviced only by qualified Service Engineers. 

 

Always remove the plug from the power socket before touching internal 
components.
