Demo Mode; Diagnostic Mode; Buzzer; Display Behaviors - Electrolux WE170V Service Manual

If the machine is switched-off and on during cycle execution without unlocking it, cycle automatically
continues like after a power failure situation.
Door status
After cycle start, the door is kept locked as far as the cycle end is reached. To open it if needed before cycle
end, Child Lock has to be deactivated first pressing the foreseen buttons combination and then pausing the
machine pressing Start/Pause button: if the machine is in safety conditions (low water level and low
temperature) the door device unlocks.
If the machine is switched-off during cycle execution for more than one minute (door lock device unlocks in
the meantime), when it is switched-on again the door is automatically locked, unless it has been manually
opened in the meantime: in this second case machine wakes up in pause and waits for user confirmation to
go on with cycle execution (pressing Start button after that Child Lock has been deactivated).

Demo mode

Demonstration mode is used to show to customers in the sales shop how to interact with user interface
panel and how the machine works by simulating the washing cycle.
The appliance works and can be operated in the same way as in normal user mode, allowing to select any
program with washing options in order to see cycle time and how options can affect it.
The difference in Demo Mode is that, once the cycle is started, only the motor moves: actions such as water
loading, water draining and heating are not performed since they cannot be managed in the shop.
4.5.3

Diagnostic mode

Diagnostic mode is used by factory or service people to test the machine and check for possible faults by
reading the alarms status history.

4.6 Buzzer

A multi-tone buzzer is provided to sound in following cases:
-
switching machine on and off, with 2 different short jingles;
-
pressing a button, with a very short "click" sound;
-
when the cycle is finished, for about 2 minutes with a specific sequence of three long beeps (1sec
on - 1 sec off - 1sec on - 1 sec off - 1sec on) repeated every 15 seconds;
-
when alarms/warnings occur, for about 5 minutes with a specific sequence of three short beeps
repeated 3 times every 15.
-
during program selection, when knob moves, with a very short "click" sound as
The buzzer can be active or not by configuration; anyway the default factory setting has to be active to
meet the norms regarding eyesight handicap people. To deactivate it the specific push buttons combination
has to be used (see "Buttons Combinations" paragraph).
When deactivated the buzzer doesn't play the on/off jingles and cycle end melody, while sounds anyway in
case of button "click", knob movements and alarm/warnings occurrence.
Volume level is pre-fixed and can't be changed by user.
