6

3. Warnings

• Any work on Electrical Appliances must be carried out by a qualified professional.

• Confirm that the Power System is operational before working on the Appliance.

• Check that the Appliance is restored to its original safety condition after the operation is complete.

• Take the plug out of the socket to disconnect the power supply before you access internal components. This
platform is not fitted with an ON / OFF switch.

• The Sensors located on the display board could be at a potential of 220 Volts (If applicable).

• Replace the heating element with the one that has the same characteristics (2
thermal fuses) to maintain safety measures for the Appliance. Do not remove / switch
the NTC sensors between heating elements (See Figure).

• Always empty the Appliance before laying it on its side for any servicing.

• Do not lay down the machine on Electronic Control System side while servicing the
unit. In such cases, some water in the detergent dispenser could sip into the electrical
/ electronic components and cause these to burn.

• The resistance values of the components shown in this SM (Service Manual) are purely
indicative and approximate.

Heating Element with
Different Characteristics

• Do not place any container under the Appliance to avoid collecting drops of water.

• Always place the cotton cloth below the machine to absorb water. There is a possibility of water leakage
while servicing the Pumps and Dispenser.

6.1 Detergent Dispenser

6.1.1 Detergent Dispenser with
Multi-Way Solenoid Valves

The water in
the detergent
dispenser is
filled through a
Solenoid Valve
for both cold
and hot water.
The detergent dispenser has 4 compartments and
one inlet for ART (Advanced Rinse Technology).

7. Electrical Characteristics

7.1 Electronic Control

The Electronic Control is made up of the following:

1. User Interface (UI) Board

2. Main Control Board (Positioned inside the machine on the right side near to the Rear Panel)

3. Motor Control Board (Positioned at the bottom left of the Appliance seen from the rear)

7.1.1 User Interface (UI) Board

The User Interface (UI) Board contains: the selector dial to select the washing programme, the LCD display to
display the programme, status, time and so on information. Buttons are available to adjust the following: the
washing temperature, the spin speed, to select an option, the degree of drying and lastly the start / pause
button to pause or start a programme, while cancel button acts as OFF.

It is possible to select the programmes by turning the selector. The options can be selected by pressing /
touching the buttons. The start / pause button is used to start the machine or pause it. The buzzer - where
featured, is powered by the User Interface (UI) Board.

User Interface (UI) Board – EFLS617SIW

13

Electrical Characteristics

7.1.2 Main Control Board

The Main Control Board supplies the power supply voltage to the Motor control and User Interface (UI) Board
and all other electrical components.

The commands acquired by the User Interface Board (by turning the selector, selecting an option and so on)
are sent to the Main Control Board, which powers all the electrical components (Solenoid Valve, Drain Pump,
Heating Element Assembly, Door Lock, Motor Control Board and the Display Board).

1. It controls the level of water via the analog Pressure Sensor.

2. It controls and monitors the status of the door.

3. It controls the temperature of the wash water via NTC probe inserted in the heating element.

4. It controls the voltage and frequency of the power supply and ensures they are close to the rated ones.

5. It controls the flow of water through the Solenoid Valve.

7.1.3 Motor Control Board

Motor Control Board transforms the energy from single-phase to three­phase, which can be modulated in breadth and frequency respectively
to adjust the power and number of revolutions of the motor.

It receives signals from the main control board and sends voltage to
the drive motor to spin the drive motor in the proper direction and at
the proper speed. The motor control board detects the speed of the
drive motor through a tachometer component. If the motor control is
not working properly, the drive motor might not spin at all or might spin
at the wrong speed.
