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.
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, antiboiling, 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:
•

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:

Time MANAGER
The “Time MANAGER” has the function to modify the programme setting, according to the type of dirt so as to
obtain a reduction or an increase of the washing time, displaying the dirt level through an icon, represented by a
t-shirt and the time through the three digits positioned on the right of the LCD display. This variation can be
modified through two buttons P8 and P7 positioned besides the display. The symbol remains lit for the whole
duration of the programme.
Please find below the various levels combined with the dirt degree.
ª Super quick (super rapid cycle) indicated for cottons and

Differences between “TC3 TIME MANAGER” and “TC3 PROPORTIONAL”
ª The P3 button refers to three LEDs (DL11÷DL13).
ª The P7-P8 buttons feature the function of “DELAYED START”.
ª In the LCD display there is not a t-shirt, but it is replaced by circle composed by three arrows which start to
move around when a programme with the “PROPORTIONAL” function is chosen (for the number of the
programmes and their position, please refer to the user manual).
4.2.2.2 PROPORTIONAL
The characteristic of the proportional programmes is that they calculate the time for the washing cycle on the
basis of the clothes weight inserted inside the drum, with the measurement of the water quantity absorbed by
the clothes. Actually, with a few clothes the water absorption will be lower and consequently also the duration of
the washing cycle; while with a bigger weight, the water absorption will be higher and also the time for the
washing cycle will last longer.
When a “PROPORTIONAL” programme is selected, the LCD
display shows the three digits that indicate the max time of the
cycle and all the available options of the programme.
After selecting the desired/featured options for the chosen
programme and pushing the START button, the appliance starts
the calculation of the effective time to perform the cycle. This is
displayed by an animation of three arrows that turn around during
this period and the time decreases.
When the appliance has terminated the calculation phase, the
digits stop flashing and the animation of the arrows disappears,
displaying the effective time of the cycle.

8 ALARMS
8.1
Displaying the alarms to the user
The alarms are displayed by the red LED of the START/PAUSE button flashing and simultaneously through the
LCD or Display.
The alarms displayed to the user are listed below:
ª E10 - Water fill difficulty (closed tap)
ª E20 - Drain difficulty (dirty filter)
ª E40 - Door open
They are represented through the flashing of the red LED inside the STARTPAUSE and can be solved directly by the user.
The alarms listed below, instead:
ª EF0 – Water leakage (Aqua Control System)
ª EH0 – Voltage or frequency out of the normal values
are displayed to the user, but for their solution it is necessary the intervention of the Service.
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.
Reading the alarm codes
It is possible to display the last three memorised alarms in the FLASH memory of
the electronic board:
• Enter diagnostics mode (par. 7.1).
• Irrespective of the type of PCB and configuration, turn the programme selector
clockwise to the tenth position.
•
•
The last alarm is displayed.
To display the previous alarms, press sequentially the left button of the
START/PAUSE button (as represented in figure).

8.2.1 Displaying the alarm
The alarm is displayed by a repeated flashing sequence of the START / PAUSE
button with red and green light (0,5 seconds on, 0,5 seconds off with a 2,5 second
pause between the sequences).
• button indicator START / PAUSE with red light → indicates the first digit of the
alarm code (family)
• button indicator START / PAUSE with green light → indicates the second digit of
the alarm code (internal number of the family)
These two LEDs are featured in all models.
Notes:
• The first letter of the alarm code “E” (Error) is not displayed, since this letter is common to all alarm codes.
• The alarm code “families” are shown in hexadecimal; in other words:
→ A is represented by 10 flashes
→ B is represented by 11 flashes
→ ...
→ F is represented by 15 flashes
• Configuration errors are shown by the flashing of all the LEDs (user interface not configured).
8.2.2 Examples of alarm display
Example: Alarm E43 (problems with the door interlock Triac) will display the following:
•
•
the sequence of four flashes of the START / PAUSE button with red light, indicates the first number E43;
the sequence of three flashes of the START / PAUSE button with green light, indicates the second number

Rapid reading of alarm codes
The last three alarm codes can be displayed even if the programme selector is not in the tenth position
(diagnostics) or if the appliance is in normal operating mode (e.g. during the execution of the washing
programme):
→ Press and hold down START/PAUSE and the nearest option button (as to enter the DIAGNOSTICS),
for at least two seconds: the LEDs initially switch off, and then display the flashing sequence indicating
the last alarm.
→ To display the previous alarms press the left button of the START/PAUSE button sequentially.
→ To return to the last alarm press the START/PAUSE button.
→ The alarm sequence continues as long as the two buttons are held down.
→ The alarm reading system is as described in paragraph 8.2.
→ While the alarms are displayed, the appliance continues to perform the cycle or, if in the programme
selection phase, maintains the previously-selected options in memory.
8.4
Cancelling the last alarm
It is good practice to cancel the last alarm:
•
after reading the alarm code, to check whether the alarm re-occurs during diagnostics;
•
after repairing the appliance, to check whether it re-occurs during testing.

11.2.1.1 Operating principle
ª When the washing programme is started by pressing the START/PAUSE button, the bi-metal PTC (contacts
3-5) is powered by the triac on the PCB: after 2 – 4 seconds, this closes the switch (5-4) which powers the
electrical components of the appliance (only if the door is closed).
ª The door interlock prevents aperture of the door while the appliance is in operation.
ª At the end of the washing programme, the PCB disconnects the interlock from the power supply, but the
door remains locked for 1 to 3 minutes (PTC cooling time).

ON/OFF = Main switch (programme

11.2.2.1 Operating principle
ª When the ON/OFF switch closes and the appliance is switched on, power is applied to the bimetallic
PTC switch (contact 4-2), but the door remains unlocked.
ª When the programme starts (Start/Pause button), the main board sends a 20 msec pulse to contacts 43 on the solenoid (at least 6 seconds must have passed since the appliance was switched on). This
locks the door and simultaneously closes the main switch (contacts 4-5), thus applying power to all
components on the appliance.
ª When the programme ends, the main board sends two additional 20 msec pulses (200 msec apart):
- the first pulse does not unlock the door
- the second pulse (which is sent only if the appliance is operating properly) unlocks the door lock
device and simultaneously opens the contacts on the main switch.
11.2.2.2 Conditions required for opening the door
ª Before pulses are sent to open the door, the main board checks for the following conditions:
- The drum must not be moving (no signal from the tachometric generator).
- The water level must not be higher than the bottom of the door.
- The water temperature must not exceed 40º C.
11.2.2.3 Automatic unlock
If a power failure occurs, if the appliance is shut off, or if the solenoid malfunctions, the bimetallic PTC will cool
down and the door will unlock in 1 - 4 minutes.

Contact closed

Signal 0
Signal 1
Turbine (with magnet and
counterweight mounted on the
outside)
Reed switch (normally open)
Magnet
Counterweight
Water entering the solenoid valve rotates the turbine (1) and magnet (3), which passes in front of the reed
switch (2), thus closing it. As this contact opens and closes, it generates pulses at a frequency that is a function
of water flow.
The turbine completes 230 revolutions for each litre of water. The operating range of the flow sensor is 0.2-10
bar.
Using the signal it receives, the microprocessor can calculate the number of litres of water passing through the
solenoid valve.
Mechanical jamming of solenoid valve
The solenoid valve may jam open without being actuated (which will cause flooding if the pressure switch
controlling the water level does not trip). If this occurs, the electronic control system (which continuously
monitors the flow sensor) will lock the door, start the drain pump and display an alarm.
Low water pressure
If the flow sensor does not generate a signal during water fill even though power is being applied to the solenoid
valve, the cause of this condition may be a closed water tap or clogged filter on the solenoid valve (with
consequent low water pressure). If this occurs, a warning will be displayed and the cycle will continue for five
minutes, after which time an alarm will be signalled.
The solenoid valve controlling residual condensed water operates during the drying phase on washer-dryers.
The alarm is deactivated because the amount of water fill is very small.

Analogue pressure switch of water level control in the tub
General features
The electronic pressure switch is an analogue device that controls the water level in the tub, used in the models
with electronic control and it is directly connected to the main PCB.
Electronic circuit
ELECTRONIC PRESSURE SWITCH
Electric symbol
The pressure switch is connected by a hose to the pressure chamber.
When the tub is filled with water, the pressure created inside the hydraulic circuit expands the diaphragm. This
in turn modifies the position of the core inside the coil, thus changing the inductance and the frequency of the
oscillating circuit.
The electronic PCB, according to the frequency, recognizes the quantity of the water in the tub.

11.9.1 Power supply to motor
The PCB powers the motor via a triac. The direction of rotation is reversed by switching of the contacts on the
two relays (K2-K3), which modify the connection between the rotor and the stator.
In certain models, a third relay (K4) is used to power the stator (full or half field) according to the spin speed.
The speed of rotation of the motor is determined by the signal received from the tachometric generator.
During the spin phases, the microprocessor performs the anti-foam and the anti-unbalancing control procedure.

Spin with little foam: if the contact of the electronic pressure switch closes on FULL, the spin phase is
interrupted; the drain pump continues to operate and, when the contact returns to EMPTY, the spin phase is
resumed.
Spin with excessive foam in the tub (critical situation): The control system detects whether the
electronic pressure switch commutates 5 times to FULL. In this case, the spin phase is skipped, and a oneminute drain cycle is performed with the motor switched off; in the case of a washing phase, a
supplementary rinse is added.

11.12 “FUCS” (Fast Unbalance Control System)
rpm
The control procedure for unbalanced loads is performed dynamically, before each spin cycle, as follows:
ª The phase begins at a speed of 55 rpm; the speed can never fall below this threshold, otherwise the check
is repeated.
ª At intervals of 300 ms, the balance is calculated and compared with predetermined limits. If the value is less
than the lower limit, the speed of the drum is increased by a certain value depending on the transmission
relation between motor pulley/drum; if the unbalancing is higher, it is decreased by the same value. The
reduction in the speed of the drum distributes the washing correctly; this procedure is repeated until the
wash load is completely balanced.
ª Correct balancing of the wash load is achieved at a speed of 115 rpm, after which the spin cycle begins.
Real speed
Selected speed
The Unbalancing Control function takes place in different phases: each phase is characterized by:
ª an unbalancing index (0-1-2-3)
ª an unbalancing threshold value (ex: 850, 350, 650, 1100rpm)
ª a time out (max. time)
• Ending of the FUCS balancing phase
The phase is ended when:
ª The drum rotation speed is 115 rpm (or 85rpm in some cases of unbalancing index). In this case the spin is
performed.
ª In some cases the optimal balancing value is not reached: a reduced spin is performed depending on the
unbalancing.
ª In the worst case, in which all phases are not sufficient to reach a minimum balancing value, the spin is not
performed.

Automatic drying cycles: the drying time is governed by the microprocessor so that the desired degree of
dryness is achieved.
The drying cycle can be performed at the end of the washing cycle, or as a separate programme. Various types
of drying can be selected:
-
extra-dry
cupboard-dry
iron-dry
Time-controlled cycle: the drying time is selected by the user (maximum 130 minutes for cotton and synthetic
fabrics).
Cooling: a cooling cycle is performed at the end of every drying cycle.
Anti-crease: after the cooling phase an anti-crease phase of a 10-minute duration is performed.
The drying heaters are powered directly by the main board via two relays.
In cycles for synthetic fabrics, drying is performed with only one heater switched on (half power); in cotton/linen
cycles, both the heaters are switched on (full power).
The fan motor is powered via a relay; the condensation solenoid is powered by a triac.
The washing of the condenser occurs at the beginning of the last rinse.
