4.1 CONTROL PANEL 4.1.1 Control panel The configuration of the control panel depends on the following: Number of programme selection buttons (from a minimum of 3 to a maximum of 6) Number of LEDs or presence of the one-digit display ON/OFF button [S0] - [S1] …...
4.1.5 Indicator LEDs The indicator LEDs provide the user with the following information: End of cycle: this LED is featured on all models. Salt: indicates that the salt reservoir is empty. If the level of regeneration is set to “1” (no regeneration), this LED remains unlit at all times.
4.2.5 Delayed start To select the delayed-start time: 1. Press button S0 to switch on the appliance. 2. Press a button to select the desired programme: the corresponding LED lights: for ex. S2, the relative LED lights up. 3. Press the button repeatedly to select the delayed-start time: •...
4.3 Cancelling a programme 4.3.1 Reset To cancel a programme that has already started: 1. Open the door carefully and press buttons S2 - S3 together for approximately 2 seconds. 2. The salt and rinse-aid LEDs light: the programme is cancelled and the appliance is in pre-selection mode.
4.5 Sequence of operations 1. Press S0 to switch the appliance on. All the LEDs corresponding to the programme/ option buttons light. 2. Press the button corresponding to the desired programme. The corresponding LED remains lit and the relative cycle phase LED starts flashing. 3.
ELECTRICAL COMPONENTS AND THEIR FUNCTIONS 6.1 EDW1100 Electronic control system The EDW1100 control system consists of a main circuit board and a control/display board. Both boards are housed in a plastic container. 6.1.1 Functions of the circuit board DISPLAY BOARD LEDs Buttons μP...
The main circuit board features an EEPROM memory (external to the microprocessor) which stores in memory data relative to the configuration, description of the cycle, cycle status in case of a power failure, and any alarm conditions. The configuration data (entered in the factory using a computer with a DAAS interface) determine the functionalities of the appliance (number and type of programmes, options, LEDs etc.).
6.3 Power supply and programme selection The main board is powered by the closure of contacts 1-5 and 2-4 of the ON/OFF button (PU). The connectors used in this case are A2 (neutral) and B1 (line). The control/display board (user interface) is powered at 5V by the main board, making programme selection possible.
6.4 Fill circuit 6.4.1 Level and anti-overflow pressure switch • The level of water introduced into the appliance is determined by the level pressure switch • The anti-overflow pressure switch ensures that the level of water does not exceed the safety threshold (causing overflow from the door).
6.5 Control of water fill phase The quantity of water necessary to carry out the washing cycle is determined exclusively by the closure of the electrical contact of the pressure switch, which changes from EMPTY to FULL. This system ensures that, if the pressure switch re-opens on EMPTY, further water is introduced until it returns to FULL.
6.7 Level stability during washing Once the fill phase has been completed, the cycle proceeds to the washing phase. The washing phase is carried out using cold or heated water, and the status of the pressure switch is monitored constantly to ensure that the hydraulic system functions correctly.
6.9 Heating The heating element is enclosed in a protective tube, and is used to heat the washing water (but does not switch on during the drying phase). The heating element is fitted to the outlet of the washing pump and connected to the duct which feeds the upper spray arm.
6.11 Deactivating the rinse-aid function Introduction of rinse-aid may be deactivated by the user by pressing a combination of buttons. In this case, the Rinse-aid LED (if featured) will also be deactivated. 1. Cancel any cycles that may have been selected (see 4.3.1).
6.13 Regeneration system Regeneration of the softening system, whose duration is approximately 4 minutes, is normally performed at the beginning of the drying phase. Each time regeneration is performed (the regeneration solenoid 4 is energized), the chamber is completely emptied (about 230 cc of water). Regeneration is controlled by the electronic control system “Ad Hoc”, i.e.
6.15 Regeneration levels The counter for execution of the “Ad Hoc” regeneration process is governed by the electronic control system on the basis of the duration of the fill phases (i.e. the quantity of water introduced), and NOT on the number of cycles.

8 Automatic cycle (only on some models) 8.1 Turbidity sensor Certain models which feature the turbidity sensor may also feature a special “automatic” programme which optimizes the cycle according to the size of the load and the degree of soiling. This sensor is positioned externally to the sump, in direct contact with the water.
9 Alarms In the event that an abnormal situation should occur which might affect the correct operation of the appliance, the circuit board causes a safety system to intervene. In most cases, this interrupts the washing cycle. The last three alarm conditions are stored in memory. Using a special procedure available only to Service Engineers, it is possible to read all the alarms stored in memory.

10 Diagnostics mode / Options A single procedure can be used by Service Engineers to access the diagnostics system. After accessing diagnostics mode, the Engineer can: • Read / cancel the alarms • Check for correct operation of the various components of the appliance •...
10.3 Cancelling alarm codes from memory / Testing the LEDs It is good practise to cancel the alarm codes: • after reading the alarm code, to check whether it is repeated during the diagnostics test. • after effecting repairs, to check whether it is repeated during testing. 1.
