Introduction; Purpose Of This Manual; Warnings; How To Proceed - Electrolux EWM10931 Service Manual

1 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 EWM10931 series, NEW COLLECTION SERIES 7/8/9 version.
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

1.2 Warnings

Any work on electrical appliances must only be carried out by qualified technicians.
The selector on this platform is not fitted with an ON/OFF switch. Before you access
internal components, take the plug out of the socket to cut the power supply.
If the heating element needs replacing, replace it with one
featuring the same characteristics (2 thermal fuses) so as not to
compromise the safety of the appliance. It is strictly forbidden
to remove/exchange the NTC probes from one heating element
to another.
Always empty the appliance of all the water before laying it on its side.
Never place the appliance on its right side (electronic control system side): some of
the water in the detergent dispenser could leak onto the electrical/electronic
components and cause these to burn.
When replacing components, please refer to the code shown in the list of spare
parts relating to the appliance.

1.3 How to proceed

1. Identify the type of control in question (page 6) and access the diagnostic cycle (See page 7)
2. Read the alarm stored (page 11) and consult the instructions regarding the "alarm codes", page 14÷17.
3. Delete the alarms stored (Page 12)
4. If you are unable to access the diagnosis mode, consult the chapter entitled "The diagnostics system
cannot be accessed" (page 19)
5. Should the main electronic circuit board need to be replaced, make sure there are no burns (See page 73)
6. After all intervention, check the appliance is operating correctly using the diagnostic cycle (page 8)
7. Delete any alarm that may have been stored during the diagnostics operations (page 12)
