Reading the last alarm condition
The diagnostics system makes it possible to identify the last alarm condition which occurred during the
operation of the appliance. To read this alarm condition, after accessing the diagnostics system (see
"Access to the diagnostics / configuration system), press the FABRICS or TEMPERATURE buttons until LED L9 lights.
The alarm condition is shown on the display, or the corresponding binary code flashes on the wash phase LEDs.
=> The first four LEDs indicate the first digit of the alarm code
=> The second four LEDs indicate the second digit of the alarm code
For example, if an E41 alarm condition (door open) is generated, the display will show E41 or (if the
appliance does not feature the display window) the second LED in the first group (equivalent to 4 in binary
code) and the fourth LED in the second group (equivalent to1 in binary code) will flash. If no alarm condition has occurred, E00 is displayed.
7.6.1 Diagnostics cycle alarms
If a malfunction should occur during the course of the diagnostics cycle, the relative alarm codes are displayed. In this case, too, the wash phase LEDs (or the display) show the error cod (flashing).
Binary codes
The table below shows how to convert the binary code displayed by the LEDs into the corresponding decimal number.
