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 controls in
the EWM0931x series, PROMETEO 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

strictly forbidden to remove/exchange the NTC probes
from one heating element to another.
