Safety Instructions _ 1
1. SAFETY INSTRUCTIONS
1-1. SAFETY INSTRUCTIONS FOR SERVICE ENGINEERS
Make sure to observe the following instructions to operate the product correctly and safely and prevent possible
accidents and hazards while servicing.
Two types of safety symbols, Warning and Caution, are used in the safety instructions.
WARNING
Hazards or unsafe practices that may result in severe personal injury or death.
CAUTION
Hazards or unsafe practices that may result in minor personal injury or property damage.
BEFORE SERVICING
• (When servicing electrical parts or harnesses) Make sure to disconnect the power plug before servicing.
Failing to do so may result in a risk of electric shock.
• Do not allow consumers to connect several appliances to a single power outlet at the
same time.
There is a risk of fire due to overheating.
• When removing the power cord, make sure to hold the power plug when pulling the plug
from the outlet.
Failing to do so may damage the plug and result in fire or electric shock.
• When the washing machine is not being used, make sure to disconnect the power plug
from the power outlet.
Failing to do so may result in result in accidental operation of the washing machine.
• Do not place or use gasoline, thinners, alcohol, or other flammable or explosive substances near the washing
machine.
There is a risk of explosion and fire caused from electric sparks.
WARNING

2 _ Safety Instructions
WHILE SERVICING
• Check if the power plug and outlet are damaged, flattened, cut or otherwise degraded.
If faulty, replace it immediately.
Failing to do so may result in electric shock or fire.
• Completely remove any dust or foreign material from the housing, wiring and connection parts.
This will prevent a risk of fire due to tracking and shorts in advance.
• When connecting wires, make sure to connect them using the relevant connectors and check that they are
completely connected.
Do not use tape instead of the connectors, it may cause fire due to tracking.
• Make sure to discharge the PBA power terminals before starting the service.
Failing to do so may result in a high voltage electric shock.
• When replacing the heater, make sure to fasten the nut after ensuring that it is inserted into the bracket-heater.
If not inserted into the bracket-heater, it touches the drum and causes noise and electric leakage.
AFTER SERVICING
• Check the wiring.
Ensure that the wiring can not be damaged by any sharp edges or moving parts.
• Check for any water leakage.
Perform a test run for the washing machine using the standard course and check whether there is any water
leakage through the floor section or the pipes.
• Do not allow consumers to repair or service any part of the washing machine
themselves.
This may result in personal injury and shorten the product lifetime.
WARNING
WARNING

Safety Instructions _ 3
BEFORE SERVICING
• Do not sprinkle water onto the washing machine directly when cleaning it.
This may result in electric shock or fire, and may shorten the product lifetime.
• Do not place any containers with water on the washing machine.
If the water is spilled, it may result in electric shock or fire. This will also shorten the
product lifetime.
• Do not install the washing machine in a location exposed to snow or rain.
This may result in electric shock or fire, and shorten the product lifetime.
• Do not press a control button using a sharp tool or object.
This may result in electric shock or damage to the product.
WHILE SERVICING
• When wiring a harness, make sure to seal it completely so no liquid can enter.
Take care when disconnecting connectors, do not use excessive force as this may damage the connector.
• Check if there is any residue that shows that liquid entered the electric parts or harnesses.
If any liquid has entered into a part, replace it or completely remove any remaining moisture from it.
• If you need to place the washing machine on its back for servicing purposes, place a support(s) on the floor and lay it
down carefully so its side is on the floor.
Do not lay it down on its front. This may result in the inside tub damaging parts.
CAUTION
CAUTION

4 _ Safety Instructions
AFTER SERVICING
• Ensure that all components are reassembled correctly and are safe before connecting the appliance to the mains
supplies.
• Check the insulation resistance.
Disconnect the power cord from the power outlet and measure the insulation resistance between the power plug
and the grounding wire of the washing machine. The value must be greater than 10Mwhen measured with a
500V DC Megger
• Check whether the washing machine is level in relationship with the floor. Check whether
it is installed firmly on the floor.
Vibrations can shorten the lifetime of the product.
CAUTION

Features Description
“12kg” Biggest Capacity in
Standard Size
“12kg“ is the Biggest Capacity in Standard Size
• The benefits for customers have been greatly increased due to the efficient use of
limited space.
• Usability has been improved due to the easier loading and removing of the
laundry.
- Time saving & Less efforts
- Energy & Money saving
- Better, Thorough Cleaning
Most Efficient • This model offers more efficient energy use compared to standard A rated
machine with the special Bubble generator system and Samsung BLDC motor.
- Eco Bubble tech.
- High efficiency BLDC motor
Bubble Wash Technology • Bubble Wash technology activates the detergent solution from the start of the
wash and generates bubbles through the Bubble Generator so that the detergent
dissolves more quickly and the detergent bubbles generated at the start of
the wash penetrate the fabric of the laundry faster and more effectively than a
conventional wash guaranteeing a cleaner wash. In particular, the lower the water
temperature is, the better the effect. In addition, since washing is performed after
the detergent is completely dissolved in the water, there is no need to worry about
any remaining detergent residue.
• Using a Samsung washing machine, you can wash waterproof clothing without
worrying about damage to material not previously washable. The outdoor care
course of a Samsung washing machine provides an excellent wash performance
and fabric care level by minimizing damage to the waterproof material.

OOPTIONAL FEATURES
The features below depend on the model.
Features Description
Water Safety System • The Water Safety System was invented for perfect leakage protection. The double
safety valve connects directly to the water tap. In the event of a leakage, the built-
in sensor immediately detects the leak within a few short seconds, automatically
turning off both the water supply and the washing machine.
- Inlet hose
It is attached to the water supply hose and
automatically cuts off the water supply if the hose
is damaged. It also displays a warning indicator.
- Leakage Sensor
A water leakage sensor attached at the bottom of the washing machine to
cutoff the power automatically if a leakage occurs.
Ceramic Heater • The ceramic heater in Samsung washing machine prevents metals in hard water
from being attach to the heater, which may cause a reduction in heater efficiency.
It saves energy, time and costs.
- Energy Savings
Over time, conventional heaters increase their power consumption an average
of 5.8 percent, while ceramic heaters only become 1.8 percent less efficient.
- Time Savings
After three years, conventional heaters take 7.5 percent longer to heat up,
whereas ceramic only lose 2.5 percent longer to heat up, whereas ceramic
only lose 2.5 percent of their ability to heat up.
