Alarms; Table Of Alarms - Electrolux Diva Service Manual

9 Alarms

In the event that an abnormal situation should occur which might affect the correct operation of the appliance, the circuit board causes a safety system to intervene. In
most cases, this interrupts the washing cycle. The last three alarm conditions are stored in memory.
Using a special procedure available only to Service Engineers, it is possible to read all the alarms stored in memory. However, only four current alarm conditions are
displayed to the user.
The alarms are displayed by means of a sequence of flashes of the END OF CYCLE LED: the display does not indicate any alarm condition.

Description of the alarm condition
Water fill time-out
(The pressure switch does not close on
FULL after 90 sec. static fill, or never
closes on "FULL" during the initial 60
sec of the dynamic fill at 2800 rpm)
Water drain time-out
(The pressure switch does not return to
EMPTY after two drain phases lasting
120 seconds) (**)
Intervention of Anti-flooding system
(the drain pump switches on)
Motor triac short-circuited
(the washing pump runs uncontrolled at
maximum speed)
Overheating
Temperature higher than 78°C
Machine status
The drain pump switches on, then
the cycle stops
The drain pump switches on, then
the cycle stops
The cycle is interrupted and the
drain pump switches on
Water fill to level (if necessary),
deactivation of the other
actuators, cycle interrupted. The
washing motor runs at maximum
speed and the alarm is displayed.
The cycle stops and the drain
pump switches on.
