1 Purpose of this manual
The purpose of this Service Manual is to provide Service Engineers, who already have the basic knowledge
necessary to repair household dishwashers, with technical information regarding dishwashers featuring the
EDW1100 electronic control system. These appliances are manufactured at Solaro (Italy).
The EDW1100 control system consists of a main circuit board and a control/display board. Both boards are
housed in a single plastic container. Some versions feature a display with only one digit.
This Manual describes:
• General characteristics
• Control panel and programmes
• Technical characteristics
• Guide to diagnostics
For more detailed information regarding the hydraulic circuits and the structural characteristics of the appliances,
refer to the Service Manual for presentation of the “DIVA” structure 599 35 55-25.
As regards the electric/electronic diagrams for a specific model please refer to spare parts list.
2 PRECAUTIONS

4.1.2 ON / OFF button (S0)
The ON/OFF button is featured on all models in the range, and is used to switch the applian ce on
and off. Switching off does not cancel the programme being executed.
4.1.3 Programme/Option buttons (S1÷S6)
These buttons are used to select the washing programme:
Press one of the buttons to select a washing programme
Within 3 seconds after selecting the programme, the user can enter the desired option(s) or select the
delayed-start function (if featured)
A specific LED is associated with each button
The dishwashers may have from a minimum of 3 to a maximum of 6 buttons
The following options may be featured:
- Delayed-start (3/6/9 hours in the versions without display and from 1 to 9 hours in the versions with
display)
- Half-load
- 3 in 1 tablet
- Extra rinse
- Sanitize
Buttons S1, S2, S3 are featured on all models; these are also used for certain Servicing functions
The functions of the various buttons depend exclusively on the software configuration of each
appliance. For more detailed information, refer to the table of programmes relative to the specific
model.
4.1.4 Programme indicator LED
1. When the appliance is switched on with S0 button (fig.1) the pre-selection phase is indicated
2. Pushing a programme button, the corresponding Led remains lit and, while the other switch off, the Led
of the current phase flashes (fig.2).
Fig.1 Fig.2
SOI/TD PR 8/35 599 35 90-23
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.
Rinse-aid: indicates that the rinse-aid reservoir is empty.
Delay time: LEDs LD7, LD8, LD9 provide a sequential indication of the time to elapse before a delayed
start (3-6-9 hours)
4.1.6 Display
The one-digit display, if featured, shows only the delay time at the start: at every pressure of the
corresponding button the time increases by one hour till max. 9 hours.
The functions of the various LEDs depend on the software configuration of each appliance.
4.2 Options
4.2.1 “ 3 in 1 Tablet”
This option can be selected by pressing the corresponding button, and remains in memory until the same
button is pressed again. This option modifies the phases of the programme in order to optimize performance
when “3 in 1” detergent tablets are used:
variation of the duration of the programme and the temperatures required to dissolve the detergent
tablets.
reduction of water exchange (partial drain phases)
exclusion of introdu ction of rinse-aid
exclusion of regeneration / resin washing
4.2.2 Extra rinse (rinse +)
This option may be selected temporarily by pressing the button (if featured), or in “Service” mode. If this
option is set by the service engineer, it remains in memory until deactivated (see relative section).
This option adds o ne cold rinse (with pulse washing) with a duration of about 5 minutes.
4.2.3 “1/2 load”
The 1/2 load option optimizes the washing cycle when only a small load is placed in the appliance.
• 1/2 load button
When this button is pressed, certain parameters of the selected washing cycle are modified:
Exclusion of Pre-wash (if feature d)
Reduction of the wa shing temperature
Reduction of the duratio n of the programme
• Automatic ½ load
When this button is not featured on the control panel, certain programmes may feature automatic
detection of the half load. This system measures variations in the temperature during the initial heating
phase. The temperature and the duration of the wash are both reduced.
This option is not available in the following cycles: “Intensive”, “Short 30 minutes”, “Soak”, “Heating
plates” and “Glassware”.
4.2.4 “Sanitize”
This is a special option used to sanitize the dishes/cutlery. However, it is NOT compatible with the
“Glassware” programme.
During the final rinse, the temperature is maintained at 68°C for 10 minutes.
If used together with the SOAK option, the system performs a special sanitizing programme which lasts
approximately 46 minutes (1 hot rinse followed by 10 minutes at a constant temperature of 68°C)
SOI/TD PR 9/35 599 35 90-23
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:
• Version with LED:
o The Led LD8 lights to indicate that the function is active and that a 3 hour time has been
set (LD8 3; LD7 6; LD6 9 ore).
o Press the button once again to cancel the delayed-start time: the LEDs LD6÷LD8 switch
off.
o The delayed-start countdown begins when the door is closed:
When the countdown is at 9 hours, LED LD6 remains lit.
When the co untdown reaches 6 hours, LED LD7 remains lit.
When the co untdown reached 3 hours, LED LD8 remains lit.
When the countdown time has elapsed (0 hours), LEDs LD6 – LD8 switch off
and the cycle starts.
• Version with display:
o The display lights up and shows “1” to indicate that the function is active and that a 1
hour time has been set.
o Pressing the button once again the time increases every hour till max. 9 hours and then it
resets.
o The countdown starts when the door is closed: the display indicates the hours till “0” and
the programme starts.

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.
3. Set the new cycle.
4.3.2 Interruption of a programme (pause)
If the button [S0] is pressed the power supply is cut and the appliance switches off.
By pushing the button [S0] again, the appliance starts and the cycle starts from the point at which it was
interrupted.
If the door is opened, the appliance is powered (the power loads are deactivated).
The LED [LD..] of the selected programme and the Option LED remain lit.
Closing the door again the cycle restarts with a little delay from the point at which it was interrupted.
Important! If the appliance is switched off or if the door is opened for more than 30 seconds during
the drying phase
, the cycle is considered to have been terminated after the regeneration phase; when
the appliance is switched on again, it returns to programme selection mode.
4.4 Power failure
The Power Failure function maintains the information relative to the cycle status even in the even of a power
outage; when the power supply is restored, the cycle resumes from the point at which it was interrupted.
If the power failure occurs during the drying phase, the cycle is conside red to have been terminated after the
regeneration phase.
The power failure condition has been defined as follows:
During a Power Fail all the loads are off in order to enable, through the energy stored in the power
capacitor of the control board, to save the data in the EEPROM and therefore when the power is
restored the cycle can restart from the point at which it was interrupted.
