3. Holding down both buttons, switch the appliance on by turning the programme selector one posi tion clockwise.

4. Continue to hold down the START/PAUSE button and the OPTION button horizontal ver si on, while for vertic al v ersion pushbutt ons are 2 and 3, until the LEDs begin to flash (at least 2 seconds).

5. To exit the diagnostics system switch the applianc e off , on and t hen off again.

IMPORTANT: The position of the START/PAUSE button varies according to the model, and is therefore not always the same.

1.2 Rapid reading of alarms

1.4 Phases of the diagnostics test

After accessing the diagnostics cycle, and irrespective of the type of control boar d fitted to the appliance (i.e. vertical or horizontal buttons) and t he c onfiguration of the selector, turn the programme selec tor clockwise to perform the diagnostics cycle for the various components and to read t he alarms. All the alarm s are enabled during the diagnostics cycle.

phase with out draini n g the water: p ass for a moment to a different ph as e of the diagnos t ic s c ycl e and then bac k t o th e h eati ng check phase (if the temperature is higher than 80°C, heating does not take place).

1.5 Reading the alarms

Proceed as follows to read the last alarm condition stored in the EEPROM on the control boar d:

• Access diagnosti c s mode.

• Irrespective of the type of control board and confi gur ation, turn the programme

selector clockwise to the tenth position.

1.5.1 Di splaying the alarm

The alarm is displayed by a r epeated flashing sequence of the two LEDs (0.4 seconds ON, 0.4 seconds OFF, with a pause of 2.5 seconds between each sequence). The buz z er (if featured) sounds a series of “beeps” in synchronization with the flashing of the LEDs.

• END OF CYCLE indicator → indicates the first digit of the alarm code (family)

• START/PAUSE → indicates the second digit of the alarm code (number

within the family).

These two LEDs are present on all models (though confi gured in different

positions) and flash simultaneously. Notes:

• The first letter of the alarm code “E” (Error) is not displayed si nc e it is the same for all alarm codes.

• The alarm code famili es are expressed in hexadecimal form. In other words: → A is repr es ented by 10 flashes → B is represented by 11 flashes → ... → F is represented by 15 flashes

• Configurati on er r or s are displayed by the flashing of all the LEDs (user i nterface not configured).

1.5.2 Examples of alarm display Exam ple: Alarm E43 (problems with the door safety interlock tri ac ) will be displayed as follows:

• four flashes of t he E ND OF CYCLE LED indicat e the first digit E43;

• three flashes of t he STA RT/ P A USE LED i ndic ate the second digit E43;

1.6.1 No t es concerning certain alarm codes

 Configuration alarms E93-E96: If these alarm s are generated (when the appliance is switched on), operation of t he appliance is blocked and all the

LEDs light. The di agnostics procedure cannot be acc essed; t he only option is to switch the appliance OFF (by turning the selector to position “0”).

 Configuration alarm E94: For this alarm code, only the family for alarm “9” is di spl ay ed; the diagnostics procedure cannot be ac c essed, and the “rapid

alarm display” function cannot be used.

 Alarms EB1-EB2-EB3: In the event of problems with the mains power supply, the appliance remains in alarm mode until the mains fr equenc y or

voltage are r estor ed to the correct value or the appliance i s switched of f (by turning the programme selector to “0”). The family of alarm “B” i s di spl ay ed; the diagnosti c s procedur e c annot be accessed, and the “rapid alarm display” function cannot be used. The complete alarm code can be read only when the abnormal situation has ceased.

 Alarms E51- E52: During the diagnostics test, all the alarms are displayed. Norm ally , when the programme selector is turned f rom one test phase to

another, the appliance exits the alarm condition and performs the phase selected. This does not take place in the case of alarm s E51 (power triac on motor short-circuited) and E52 (no signal f r om t he tachymetric generator on the motor): in these cases, the only option to exit the alarm condition is to switch the appliance OFF by turning the selector t o position “0” (reset).

Independently of the type of selector, after activating the diagnostics system, the operation diagnostics of the different components and the reading of the alarm s can be performed, by rotating the sel ec tor clockwise. In models with digit the code of the selector position is display ed for a second. In the diagnostics cycle all alarms are activated. If duri ng the cycle operati on an alarm occurs, the appliance blocks and the LEDs (and the display) flash indic ating the relative code.

2.10 Reading the alarm codes

In order to read the last alarm code memorized in the EEPROM on the PCB: with knob

• Enter diagnostics mode

• Irrespective of the type of PCB and configurati on, t urn the

programme sel ector clockwise to the tenth position.

without knob

• Press the Fabrics (1) or Temper ature (2) button until LED L10 lights.

2.10.1 Displaying the alarm

The alarm is displayed by a r epeated flashing sequence of the two LEDs (0.4 seconds lit, 0.4 seconds off, with an interval of 2.5 seconds between sequences).

The buzzer (if featured) will sound “bips” in synchronization with the flashing of the LEDs.

• END OF CYCLE LED → indicates the first digit of the alarm code (family)

• START/PAUSE → indicates the second digit of the alarm code (number

within the family)

These two LEDs are featured on all models (though they are configured differently), and flash simultaneously.

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 “f amili es” are sho wn in hexadecimal; in other words:

→ A is represented by 10 fl ashes → B is represented by 11 fl ashes → ... → F is represented by 15 flashes

• Configurati on er r or s are shown by the flashing of a series of LEDs.

2.10.2 Examples of alarm displays

Example: Alarm E43 will displ ay the following:

• On the display, if featured, E43

• The sequence of four flashes of the End-of-cycle LED indicates the first number E

• The sequence of three flashes of the Start/Pause LED indicates the second number E4
