Alarms; Displaying The Alarms To The User; Alarms Displayed During Normal Operation - Electrolux Washing machines with EWM 1000 PLUS Service Manual

9 ALARMS

9.1 Displaying the alarms to the user

Control of the alarm system can be configured; according to the model, therefore, some or all of the alarms
may be displayed to the user.
Normally all the alarms are displayed to the user except for:
- E10 – water fill
E20 – drain water
-
E40 – door closure
-
E90 – configuration
-
The alarms are active during the execution of the washing programme; except for the alarms relative
to the configuration and power/frequency supply which are displayed also in the selection phase.
The door can normally be opened (except where specified) when an alarm condition has occurred on
condition that:
•
The level of the water in the tub is below 1st level
•
The temperature of the water is lower than 55°C
Certain alarm conditions require that a drain phase be performed before the door can be opened:
•
Cooling water fill if the temperature is in excess of 65°C
•
Drain until closure of both pressure switch contacts (1st level and anti-boiling safety system) on EMPTY
within a maximum of 3 minutes.
9.1.1

Alarms displayed during normal operation

The type of alarm condition is displayed to the user by the repeated flashing of the END
OF CYCLE LED (0.4 seconds lit, 0.4 seconds off, with an interval of 2.5 seconds
between sequences). This LED is featured on ALL MODELS, though configured in
different positions.
If, for example, the user should forget to close the door, the
control system will detect alarm E41 about 15 seconds after the
start of the cycle; the cycle remains in PAUSE mode and the
display, if featured, would display E40.
Simultaneously the LED end-of-cycle flashes repeating the
sequence indicated in the table.
The four flashing indicate the first of the two digits of the alarm
4
E 1 (the alarms relative to a same function are grouped by
families).
In this case, once the door has been closed, it is sufficient to
press the start button to start the programme.
