- The week of construction of the appliance;
- The progressive number of construction.
EXAMPLE:
Serial Number 91610002
94th digit of the year of construction
16 Week of construction
13th digit of the year of construction
0002 construction sequential number
In this case, the appliance is the second (0002) machine built in week 16
of the year 2019.
The Serial Number is necessary to find the correct spare part in the
spare parts catalogue and it is mandatory to ask technical support
from the Manufacturer.

2 INSTALLATION AND COMMISSIONING
2.1 INSTALLATION
Please, for installation refer to Installation and Operting Manual available on website https://www.electroluxprofessional.com
or https://webgate.electroluxprofessional.com
2.2 COMMISSIONING
To avoid accidents, when debugging the machine please pay special attention to the following:
• The debugging can only be carried out by professional service partner;
• Please check the installation tools and other items are all removed in initial start;
• Check for possible water and chemical leakage;
• Check if the security system and door switch are normal when debugging
• Check that all screws are tightened.
When the installer completes all installation work and all the settings work, the machine can start running.
Please, for commissioning refer to Commissioning and preventive maintenance checklist available on website
https://www.electroluxprofessional.com or https://webgate.electroluxprofessional.com
2.2.1 PRELIMINARY CHECKS
A function check must be made when the installation is finished and before the machine can be ready to be used.
Whenever a repair has been made, a function check must be performed before the machine can be used again.
Identify the equipment on data plate:
- Model
- PNC
- S/N
A function check must be made when the installation is finished and before the machine can be ready to be used. Whenever a repair has been
made, a function check must be performed before the machine can be used again.
Check the interior
Open the door, make sure that all parts are placed in correct location.
Make sure that there are no irrelevant parts inside the machine (for example: hanging cloth, screws, nuts, tools, packaging materials, etc.).
Water inlet hose
Please clean the inlet hose before connection. Before initial water feeding, please disconnect all heater and power supply to avoid heating with no
feeding water.
Water supply connection and related flow pressure
Check if the inlet hose is connected firmly, as looseness and leakage may happen in transporting and carrying process. Related non-standard flow
pressure can lead to faults of the machine.
Electrical Connection
Connect the mains plug to the mains socket only at the end of the installation. Make a visual test for all the electrical equipment if they are in good
condition, (for example: switches, cables, motor shell, etc.), and test all the functions of power switch.
When the machine is switched on for the first time, the display shows a series of data that the installer must enter.
Once the data has been set, it will no longer be requested when switching on, unless the initial state is restored from the menu.
Please refer to the Installation and Operting Manual available on website https://www.electroluxprofessional.com or
https://webgate.electroluxprofessional.com
Check the automatic stop of the machine
Start the machine and check if the micro switch is working properly: the machine must stop if the door is opened.
Ready to use
If all tests are OK the machine is now ready to be used.

SERVICE MANUAL
2.2.2 BASIC OPERATION TO TEST THE MACHINE
1. Preliminary checks
1. Water analyses and power
supply.
1. Using the special tools indicated in chapter 6.1.2 Special tools,
perform the following water analyses:
- Total water hardness;
- Temporary water hardness;
- Water inlet pressure;
- Water inlet temperature;
- pH;
- Conductivity;
- ppm;
- Chloride;
In case of water treated dishwashers (water softener and/or reverse
osmosis) consider to perform the water analyses even upstream the
water treatment.
Water quality affects the dosage of detergent and rinse aid.
It is strongly raccomended Electrolux Professional C11 or C13
Detergent aid. It is trongly raccomended Electrolux Professional
C12 or C14 Rinse aid.
2. Check if the socket power supply respects the values requested by
the appliance
2. Components fitting check Make sure the overflow pipe, the tank filters, the upper and lower arms
are correctly fitted.
2. Ensure that regeneration cycle,
machine water incoming, heating
program operates normally
1. Regeneration cycle
In case the dishwasher is equipped with automatic water softener, fill
the salt tank with kitchen rock salt, add 2 glasses hot water inside it,
close the cap and switch on the dishwasher.
Before filling the tank, the dishwasher prepares the resins by letting the
water flow through salt to perform the regeneration process.
2. Open the water supply main
tap, connect the plug, close the
machine power switch; power
indication light is on A
1. Observe if the water flows into boiler.
- if there is sounds of water flow.
- check if the valve is open:
(place screwdriver to the coil, if there is magnetic attraction means the
valve is connected to power, there is no water passing, or it is broken
or the pipe are blocked, the water source are not open).
- wait few minutes to see if the water is flowing into tank --> that means
the boiler is full.
2. Open and close the door to check if door switch operates correctly
stopping the filling valve.
3. When the water reaches the right level, the pressure switch diverts
the contact to power the boiler heating element. When the temperature
in the boiler is reached, the tank heating element starts to heat.
4. Check if the piping system, tank, boilers are leaking.
5. When the start cycle botton G lights green, the tank has reached the
correct temperature and the appliance is ready to be used.
3. Make sure washing, rinsing and
draining operate properly
1. Start a washing cycle when the
appliance is ready to be used
1. Press start button G.
2. Display shows the cycle running.
3. Wait until the cycle finishes and check the rinse process has been
accomplished.
2. Calibration of the dispensers
The concentration of detergent/rinse aid depends on the type of
product used and the supply water hardness (check the characteristics
on the product label).
Follow the first installation settings, in order to fill the dispensers pipes:
1. Rinse aid dispenser adjustement: to vary the rinse aid dose, enter
the parameter menu.
To check the efficiency of the rinse aid look at a freshly washed glass.
Drops of water indicate an insufficient dosage while streaks indicate
an excessive dosage which can either be caused by the density or the
quantity. It is strongly raccomended Electrolux Professional C12 or
C14 Rinse aid.
2. Detergent dispenser adjustement: to vary the detergent dose, enter
the parameter menu. The adjustment of the amount of detergent
delivered by the pump must carefully comply with that indicated by
the detergent producer. It is strongly raccomended Electrolux
Professional C11 or C13 Detergent aid.
3. Start the tank drain
Hold pressed the drain pump button D for 2 seconds to enable the
drain pump. Display shows "Remove the overflow pipe". After removing
it, wait up to the tank has been drained completely, a gurgling sound
can be heard, indicating that the tank has emptied.
