1 Purpose of this manual
The purpose of this manual is to provide service engineers who are already familiar with the repair procedures
for traditional washing machines with information regarding appliances fitted with the ENV06 electronic control
system and produced in Porcia (Italy) and Olawa (Poland).
The characteristic of the ENV06 electronic control system is to use only an electronic pressure switch to check
the various water levels in the tub (with the elimination of the mechanical pressure switches: anti-overflow, anti-
boiling, 1st-2nd level), and a new heater with two thermal fuses which interrupt if the temperature degree
overcomes the values by which they are calibrated.
The following are described:
•general characteristics
•control panel and washing programmes
•technical and functional characteristics
•access to the electronic control system
For detailed information concerning hydraulic circuit, structural characteristics of the appliances and
accessibility, please refer to Service Manual:
•Publication no. 599 37 67-82 – washing machines with HEC-ARCHED cabinet.
2 PRECAUTIONS
Electrical appliances must be serviced only by qualified Service Engineers.
Always remove the plug from the power socket before touching internal
components.
In case of replacement of the heater, replace it with one with the same
characteristics in order not to compromise the safety of the appliance.

EXECUTION OF WASHING PROGRAMME
During the washing cycle, the display shows: the name
of the selected programme, the temperature and the
spin speed of the cycle, the cycle phase and under an
animated bar that indicates the washing cycle carried
out (dark par of the bar) and the part of the programme
to be executed (light part). In the top right corner, the
remaining time of the cycle appears, under it the time
at which the washing cycle ends (both the duration
time and the end-of-cycle time can be influenced by:
dirty filter, etc. and this includes the changing of the
end-of-cycle time proposed at the start of the
programme) and the options if they have been
selected.
The main phases of washing programme are seven:
Water fill, Heating, Washing, Rinses, Drain, Spin and
End.
PAUSE
A washing programme can be blocked momentarily
during its execution pushing button P6: the LED starts
flashing; the animated bar stops and it appears above
“PAUSE”.
During this time, it is possible to change the options
and open the door if the temperature and the water
level are low.
END OF CYCLE

4 DEMO
A special programme allows the demonstration of the operation of these appliances in shops, without the
connection to the water system, in an interactive way with the user:
♦The interactive way consists in selecting any programme, introducing some options and, after pushing the
start button, the appliance will execute only some phases of the programme, skipping those that cannot be
performed (water fill, drain, heating).
The cycle is performed as follows:
ªThe door lock device is activated normally (door locked during the operation, possibility to open it at the end
of the cycle or in pause).
ªMotor: all movements at low speed are activated; the pulses and the spin are deactivated.
ªThe water fill solenoids and the drain pump are deactivated.
ªLCD: it displays all the programme phases very quickly.
ªAlarms: for safety reasons the alarm families E40 (door closing), E50 (motor) and E90 (communication
between board/configuration) are enabled.
If after the setting of the Demo, the options and the programme are not modified, after three minutes a
continuous cycle starts with the displaying of the various programme phases represented by the DISPLAY
without powering the functional parts of the appliance.
To exit DEMO function, switch the appliance off.

6 ALARMS
6.1 Displaying the alarms to the user
The alarms are displayed by the flashing of the yellow LED placed above the
START/PAUSE button and simultaneously through the LCD.
The alarms displayed to the user are listed below:
ªE10 - Water fill difficulty (closed tap)
ªE20 - Drain difficulty (dirty filter)
ªE40 – Door open
They can be solved directly by the end user;
While the alarms listed below:
ªEF0 – Water leakage (Aqua Control System)
ªEH0 – Voltage or frequency out of the normal values
They are displayed to the user, but for their solution it is necessary the intervention of the Service.

SOI/DT 2007-10 dmm 19/48 599 70 27-90
The alarms are enabled during the execution of the washing programme, with the exception of alarms
associated with configuration and the power supply (voltage/frequency), which are also displayed during the
programme 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 a certain level
•Water temperature lower than 55°C
•Motor stopped
Certain alarm conditions require that a drain phase be performed before the door can be opened for safety
reasons:
•Cooling water fill if the temperature is higher than 65°C
•Drain until the analogue pressure switch is on empty, during a max. 3-minute time.
