This washing machine is intended only for cleaning dishes, plates, forks, knives etc. Be care-
ful in order to wash items suitable for dishwashing. Solid food residuals should be removed
from the items before washing them in the machine. For better results you could soak the
items for some time, especially if there is elapsed enough time after usage. Do not use this
machine for washing items that were in service / contact with acids, mineral oil, grease, gas-
oline or colors.
Preparation*
Fill the baskets placing the glasses and cups with the opening facing down in the locations of
the basket that have the correct molding.
Plates should be stacked vertically in appropriate baskets without touching each other.
In any case avoid the overloading of the baskets.
*
Special care should be given so that the highest point of the flexible drainage hose is placed
lower than 650 mm. Otherwise, reverse flow of the water could occur.

Control*Panel*
*
Starting*the*machine*
In order to start the machine, press the Button SW6 (ON) for 3 sec. The LED L6 flashes red
and a buzzer sounds.
Procedures*before*washing*
Since the washing machine is switched on, the boiler and the wash tank start filling with
water. Next, the machine gets filled with detergent and rinse aid. During these, a “FILL” mes-
sage appears on the Dash. After the tanks are filled with water and the necessary detergent
and rinse aid liquids are captured, the boiler’s heating resistance and the wash tank’s
heating resistance start working sequentially (after reaching boiler’s temperature of ope-
ration, its resistance shuts down and the wash tank starts heating). On the LCD1 & LCD2
screens the current temperature of each tank is displayed alternately (when LCD 1 shows
“bt” then LCD 2 displays boiler’s temperature; when LCD 1 shows “tt”, then LCD 2 displays
tank temperature). In case that the wash tank’s heating resistance is ON, a dot in the right
lower corner of LCD1 is lit, while in case that the boiler’s heating resistance is ON a dot in the
right lower corner of LCD2 is lit. For that reason, symbol (representing the tank) is
shown beneath of LCD1 & symbol (representing the boiler) is shown beneath of LCD2.

Standby*
During Standby operation (after the automatic set up procedures), LCD 1 & LCD 2 should dis-
play the temperature of the wash tank & boiler tank alternately.
LCD1 LCD2
bt or tt (alternating) --
℃
If the machine stays on Standby mode for more than 30 min, then it turns into sleeping
mode for minimizing power consumption. When this occurs, LCD 1 & LCD 2 turn off and L6 is
flashing. By pushing SW6, the machine is again ready for operation.
Thermo-Protector*
In order to start the first washing cycle of the day, both temperatures in the tank and the
boiler must reach operational values (60
℃
& 85
℃
respectively). In all the other cycles, due
to Thermo-Protector system, if the temperature in the boiler is not appropriate for rinsing,
the washing cycle continues until the rinse water becomes sufficiently heated. A message
on the screen informs the user that the washing cycle continues; LCD1 shows the current
value of the water temperature in the boiler and LCD2 shows “ht” (i.e. heating).
Washing*Cycle*Selection*-*Start*
This washing machine has three washing cycle program options. The user could choose be-
tween short, medium and long program by pushing one of the buttons SW1, SW2 or SW3 ac-
cordingly. After pushing the corresponding button, the washing cycle starts automatically,
UNLESS the door is accidentally open. In the latter case a message “door” is shown in the
Dash and the washing starts again as soon as the door is closed. The remaining time (in
seconds) is displayed on the Dash.
Important note: In case that the door is open accidentally before program is finished, the
washing stops and the timer resets. Therefore, in order to finish the cycle, you should start
the procedure from the beginning.
Important note: 10 sec before finishing main wash the draining pump starts working and it
stops 10 sec after rinse cycle.
After completion of the washing cycle, a message “end” on the dash informs the user that
the program is finished. The message appears until the door is opened again.
Draining*
This machine has draining pump, so that the draining cycle is performed automatically. If
you want to perform draining on demand, please remove the overflow hose that is placed
on the wash tank and press the Button SW4. After 15 sec the draining starts and LED L4
flashes.
During draining, an internal check of the system is performed, ensuring that the heating
resistances are switched off. In that sense, any possible overheating caused by heating re-
sistances not immersed in water is avoided. As soon as draining stops, for the next 30 sec
the system performs self-cleaning (door must be closed).

Kindly note that after every On-Demand draining execution, the machine shuts down.
Filling*of*Detergent*and*Rinse*Aid*
This machine is equipped with peristaltic pumps for the rinse aid and the detergent filling.
The filling inlets for each one are the two corresponding hoses which should be immersed in
the appropriate tanks.
The filling procedure is performed in two stages. The initial filling (when you turn the ma-
chine on) and additional re-fillings after each washing cycle:
1st Stage: During automatic preparation (before the first wash) the machine receives from
the tank soap for 180 sec and rinse aid for 35 sec. This could be adjusted from the user th-
rough the User Menu *Check Section “User Menu”.
2nd Stage: During every complete washing & rinsing cycle, the machine receives detergent
for 13 sec and rinse aid for 12 sec. This could be adjusted from the user through the User
Menu *Check Section “User Menu”
NOTE: In case that you need to adjust the Detergent or Rinse Aid from the User Menu,
please bear in mind that for each second the corresponding pump captures the following
liquid quantities:
Detergent pump: 0.83 ml/sec
Rinse Aid pump: 0.19 ml/sec
By multiplying these quantities with the time duration (seconds) that the pump works, you
can calculate the volume of each liquid that it is used.
Warning: The machine receives rinse aid during washing cycle and detergent during rinsing
cycle.
Cold*Water*Rinse*
This machine has Cold Water Rinse operation. It could be activated in order to be performed
after every washing cycle or for On Demand occasions.
In order to perform a Cold Water Rinse after one washing cycle, press Button SW5 for 1 sec.
A single sound buzz will inform you that the machine is set up for a single cold rinse
performance. Then, LED L5 will be on, while the procedure is performed.
In case that you wish to perform Cold Water Rinse after each washing cycle, press hold But-
ton SW5 for 5 sec while the machine is on Standby mode. A double sound buzz will inform
you that the machine is set up for a cold rinse performance after every washing cycle (LED L5
will lit). Should you undo the selection, please repeat the above procedure.

8
Shutting*down*the*machine*
In case that you want to shut down the machine, remove the overflow hose in the wash tank
and press the Button SW4. The machine is going to drain automatically the used water,
perform a self-cleaning cycle and then shut down. An alternative way is to press
continuously the Button SW6 until the indication “OFF” appears in the first line of the screen
(it will take about 5 sec). The recommended way is the first.
ECO*Function*
In case that the machine is in Standby operation for more than 15 minutes, the Boiler’s
temperature lowers in order to avoid unnecessary power consumption. During these
intervals, if the door of the washing machine opens, the ECO Function stops.
Soft*Start*Function*
This machine is equipped with Soft Start System that enables the water pump to start with
lower pressure and gradually increases it, so that the sensitive crystals are not damaged.
User’s*Menu*
In order to enter the User’s Menu, shut down the machine and press hold Buttons SW1,
SW3 & SW6 at the same time for 3 sec with the door closed. LED L6 flashes and a beeper
sounds three times. Message “conf” apears for a few seconds and the User’s Menu is
activated.
Find the parameter that you wish to adjust using Buttons SW3 and SW4 for navigation inside
the menu. The corresponding parameter will be displayed on the screen.
Should you wish to increase the amount (+), press Button SW1
Should you wish to decrease the amount (-), press Button SW2
After defining the value, press Button SW5 once in order to register the value in the
memory.
