1 INTRODUCTION

1.1 Purpose of this manual

The purpose of this Service Manual is to provide a simple and clear description of the
procedure to be followed by service engineers when confronted by problems identified by
the various alarm codes generated by appliances with the ENV06 electronic control
system version EWM25xx and EWM35xx.
Depending on the configuration of the appliance, the alarm codes may be displayed
partially or completely to the user (the alarm codes are generally displayed partially).
The diagnostic system can be used by service engineers for the following purposes:
♦ To read the alarms
♦ To cancel alarm conditions stored in memory
♦ To test the operation of the appliance

1.2 Procedure

1. Identify the type of control system (page 7/8) and access the diagnostic cycle
(See page 9).
2. Read the alarm code stored in memory (page 13) and refer to the instructions for the
corresponding alarm code, (page 17-21).
3. Cancel the alarm stored in memory (page 16).
4. If access to the diagnostic cycle is not possible, refer to the section "Access to
diagnostic system impossible" (page 23).
5. If the main PCB is replaced, check that there are no burned parts (see page 119-120).
6. After any repair, always check the operation of the appliance using the diagnostic cycle
(page 10).
7. Cancel any alarms stored in memory during the diagnostic procedure (page 16).
