INTRODUCTION

1.1 Purpose of this manual

The purpose of this manual is to explain, simply and schematically, the steps any Technician should take when
faced with the problems indicated by the various alarm codes on appliances with electronic control in the
EWM09312 New Collection series.
Depending on the appliance configuration, the alarms may be entirely or partially displayed to the user: the
latter solution is usually adopted.
The diagnostics system is used by Service Technicians to:
• Read alarms
• Delete the alarm stored
• Test the appliance operation

properly by using an appropriate tool and follow the instructions described/illustrated on the
Electrolux Learning Gateway portal

though it were straight off the assembly line.
