Be careful during measurements in the live voltage section. The primary side of the power supply, including the heat sink, carries live mains voltage when you connect the player to the mains (even when the player is “off”!). It is possible to touch copper tracks and/or components in this unshielded primary area, when you service the player. Service personnel must take precautions to prevent touching this area or components in this area. A “lighting stroke” and a stripe-marked printing on the printed wiring board, indicate the primary side of the power supply.
. Never replace modules, or components, while the unit is “on”.

With this procedure it is possible to access the Service Diagnostics System. Once this mode is accessed, it is possible to:
• read and cancel the alarms
• control the operation of the various components of the appliance
• start the Service diagnostics mode
Reading the alarms and activating the individual components
To activate the function:
1) Press and hold down the button S1. T
2) Turn the knob anti-clockwise till Position 5:
* The LEDs LD0 and LD1 flash.
* Release button S1.
* Press button S1.
* the first memorised alarm is displayed: the End of cycle LED flashes and pauses: for the de-codification,
please refer to table of alarm codes.
4) Press again button S1 to display the second alarm.
5) Pressing button S1 again, the third alarm is displayed.
6) Pressing button S1 for the fourth time, the appliance
actuators are activated:
* 4th actuation: regeneration solenoid
* 5th actuation: drain pump
* 6th actuation: water fill solenoid (water up to level)
* 7th actuation: heating (only if water up to level)
* 8th actuation: washing pump
* 9th actuation: detergent/rinse-aid dispenser
* 10th actuation: drying fan
* 11th actuation: it starts again from the first alarm
All positions can be repeated pushing button S1 sequentially.

The components are powered with door closed. If button S1 is not pressed for 60 seconds, the diagnostics terminate automatically

Cancelling alarm codes from memory / test of LEDs
It is good practise to cancel the alarm memorised:
• after reading the alarm code, to check whether it is repeated during the diagnostics test.
• after repairing the appliance, to check whether it is repeated during the testing cycle.
To activate the function:
1) Press and hold down button S1.
2) Turn the knob anti-clockwise till Position 5:
* the LEDs LD0 and LD1 flash.
* release button S1.
3) Turn the knob till Position 4.
* Press button S1.
* All LEDs start to flash for 30 seconds.

Functional testing cycle
This is an abbreviated washing programme (50 min) which allows the Service Engineer to test all the functions that comprise a traditional washing cycle; in effect, the system simulates a normal cycle.
Selecting the cycle
To activate the function:
1. Press and hold down button S1.
2. Turn the knob anti-clockwise till Position 5.
* The LEDs LD0 and LD1 flash.
* Release button S1.
3. Turn the knob till Position 3
* press button S1.
* The programme starts: the programme behaves as in a normal cycle; the PAUSE and CANCEL options are accessible.

[At the beginning of the subsequent programme (i.e. after the test cycle), the resins are washed. The overall duration of the test cycle is about 50 minutes.]

Exiting Service and User modes
To exit these modes, turn the knob to OFF position and switch the appliance off or wait 60 seconds:
the LEDs light up and the appliance returns to selection mode.

Electrical circuit diagram and table of programmes

TABLE OF PROGRAMMES
The table below lists the phases of the programmes for this type of appliance. As these can be configured differently, refer to the relative documentation for the specific cycles available for each mode.

N.B.: The overall times for the programmes (duration) are approximate, and do not take into consideration the extra rinse, which may be selected as an option. The various phases do not include the times for regeneration/washing of the resins which, being performed “Ad Hoc”, are not carried at at every cycle.

CHECKING THE EFFICIENCY OF THE COMPONENTS
In order to facilitate the control procedure for the components to be tested, a TEST PROCEDURE has been created which indicates the point to which the probes of the tester should be applied and the correct theoretical value for each component tested.
* Remove the door and detach all the connectors from the main board.
* Connect the probes of the tester to the appropriate points on the connector. Compare the ohmic reading with the theoretical value.

Care should be taken relative to the position of connector "B1" - "B2": if this connector is replaced in the incorrect position (back-to-front), the appliance will not function since the power supply will be disconnected.

Measurement points on the board wiring connectors

The special functions.

The table below briefly describes how each of the special functions available to the user and to the Service Engineer can be used. To activate the user mode, the selector must be turned anti-clockwise.

ALARMS
When an abnormal situation occurs that may interfere with machine functioning, the main board activates a safety system which in most cases interrupts the washing cycle. The last three alarm situations are stored in memory. Using a special procedure, service personnel can display all the alarms stored in memory. The user is only shown four of the alarms in progress.
The END OF CYCLE LED flashes repeatedly.

Table of alarm codes

If it is not possible to access diagnostics mode, switch the appliance off and then on again to check that this is not caused by a temporary fault. Before replacing the circuit board, check that it is correctly powered by controlling the following
* Continuity of the power cable
* Correct operation of the suppressor
* Closure of the door switch contacts
* Continuity of the wiring between connectors on the circuit board and the suppressor.

USER MODE
With this procedure it is possible to:
• Modify the regeneration level selection (depending on the water hardness).
• Activate or deactivate the rinse-aid supply.
Regeneration selection
To activate the function:
1. Press and hold down button S1.
2. Turn the knob to Position 1:
* The LEDs LD0 and LD1 flash
* Release button S1
3. Press button S1
* The regeneration level is displayed by the End of cycle LED which flashes and pauses at intervals: for the de-codification, see summary table of alarms.
Press button S1 to increase the regeneration level according to the following values:
