9.4.2 Errors codes / Alarm codes
Display ing the alarms to the user
Operation of the alarms is configurable according to the model. Some or all of the alarms may be displayed to the
user. Normally, all alarms except E44, E52, E63, E94, EB2 are displayed to the user.
When an alarm condition occurs, the drying cycle may be interrupted or paused; in some cases, for the sake of
safety, a forced cooling cycle is performed. In this case, the electronic board, if possible, disconnects the power relay
from the heater unit and powers the motor of the drum cooling fan. The cycle remains active until the user switches off
the appliance.
Reading the alarm codes
To read the last alarm code memorized in the EEPROM of the electronic board, proceed äs follows:
- Access diagnostics mode
- Turn the Programme selector knob clockwise to the eleventh position.
Displaying the alarm code
- First digit: letter „E"
- Second digit: the family of the alarm
- Third digit: the number of the alarm
Reading the alarm codes
The last alarm code memorized can be displayed even ifthe appliance is in normal operating mode (e.g. while the drying
Programme is being performed):
- Press (start/pause) and the first button in the left of it simultaneously for at least 5 seconds: the display shows
the last alarm.
The alarm sequence continues to flash as long as the two buttons are held down.
The appliance continues the cycle while the alarm codes are being displayed. If the appliance is in Programme
selection mode, the options previously selected are stored in memory.
Cancelling the last alarm memorized
It is good practise to cancel the alarm code from memory:
- After reading the alarm, to check whether it is repeated during the diagnostics cycle.
- After effecting repairs to the appliance, to check whether it is repeated during testing.
- Access diagnostics mode and turn the Programme selector knob to the eleventh position (alarm reading)
- Press buttons 6 (start/pause) and 4 simultaneously.
- Hold down buttons 6 and 4 (about 5 seconds).
- Once the alarm has been cancelled, EOO is displayed.
Notes concerning certain alarm codes
-Configuration alarm E93:
When configuration alarms are displayed (when the appliance is switched on), the appliance is inoperative and all the
LEDs light. It is not possible to access diagnostics mode; the only possible Operation is that of switching off the
appliance (selector knob on position „0").
Alarms EB1-EB2-EB3:
In the event of problems with the power supply, the appliance remains in alarm mode until the voltage and frequency
are restored to within the normal limits or the appliance is switched off (selector knob on position „0"). Alarm family „B"
is displayed and it is not possible to access diagnostics mode norto use the „rapid alarm display" function. The
complete alarm can be read only when the abnormal condition has terminated.
