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.
Hazards or unsafe practices that may result in severe personal injury or death.
WARNING
Hazards or unsafe practices that may result in minor personal injury or property damage.
CAUTION
WARNING
• (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 electric shock or fire due to lightning.
BEFORE SERVICING
• Do not place or use gasoline, thinners, alcohol, or other fl
machine.
There is a risk of explosion and fire caused from electric sparks.

WARNING
• 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.
If tape is used instead of the connectors, it may cause fire due to tracking.
WHILE SERVICING
• Make sure to discharge the PBA
Failing to do so may result in a high voltage electric shock.
• When replacing the heater
If not inserted into the bracket-heater, it touches the drum and causes noise and electric leakage.
WARNING
• Check the wiring.
Ensure that no wire touches a rotating part or a sharpened part of the electrical harness.
• 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.
AFTER SERVICING
power terminals before starting the service.
, make sure to fasten the nut after ensuring that it is inserted into the bracket-heater.
• If it seems that grounding is needed due to water or moisture, make sure to run
grounding wires.
(Check the grounding of the power outlet, and additionally ground it to a metallic water
pipe.)
Failing to do so may result in electric shock due to electric leakage.
[Running a grounding wire]
Twist a grounding wire (copper wire) two or three times around the tap.
-
- If you connect the grounding wire to a copperplate, bury it 75 cm under the earth in a
place with a lot of moisture.
Do not connect the grounding wire to a gas pipe, plastic water pipe or telephone
wire. There is a risk of electric shock or explosion.

CAUTION
• 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.
BEFORE SERVICING
• Do not press a control button using a sharp tool or object.
This may result in electric shock or damage to the product.
CAUTION
• When wiring a harness, make sure to seal it completely so no liquid can enter.
Make sure that they do not break when force is exerted.
• 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.
WHILE SERVICING
• 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
• Check the assembled status of the parts.
They must be the same as before servicing.
• 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 10MΩ when measured with a
500V DC Megger
AFTER SERVICING
• Check whether the washing machine is level in relationship with the floor
it is installed firmly on the floor.
Vibrations can shorten the lifetime of the product.

for minimizing damage to the washing.)
- The embossed wall of the drum serves as a washboard, dramatically
increasing the washing performance compared with existing drum washing
machines, which use the power of the difference in elevation only
- The size of holes has been reduced drastically, maintaining the optimal wash
performance (Washing Cost 1.0) while saving on water and electricity required
for washing.
- The structure of the holes on the diamond drum has been changed minimizing
potential damage to the washing since it is difficult for strands to enter the
holes.

OPTIONAL FEATURES
► The features below depend on the model.
Features Description
Air Refresh System • Sterilization/Deodorization/Removal of Ticks without Water Washing (Air Washing
Using Air and Heating)
Destroying bacteria and ticks without the use of water
-
- Removing the sweat and dirt odors
- Maintaining the shape and color of the washing without dry-cleaning
• Washing with air.
- Removing odors by heating, keeping the washing as new.
- Washing with air conveniently, compared with dry-cleaning
The goal of deodorization is 60 percent. (40-minute cycle)
• Washing one or two shirts in 30 minutes
- If a piece of clothes is not completely dry when it is humid, the machine can
dry it within 30 minutes
• Preventing bio-film caused by humidity from occurring
- You do not need to worry about the humidity inside the drum.
- The drum is dried regularly, preventing bio-film.
Water Safety System • The Water Safety System has invented for perfect leakage protection. The double
safety valve connects directly to the water faucet. 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 attached to the water supply hose and automatically
cuts off water flow when hose 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, to prevent danger of a fire.

Features Description
Silver Wash System • Samsung’s unique technology generates silver ions that remove bacteria and
fungi, and create an invisible shield that protects your clothes from unwanted
odors until your next wash. Using an ancient and proven purification technique so
simple, yet so advanced it removes microbes even in cold water.
• Effect of Silver W
ash System
- Keeps Stored Clothes Fresh
Ag+ Silver (Nano) Technology anti-bacterial effect keeps fabric free from
The
odor-causing micro-organisms for up to one month, without the use of strong
chemical cleaners. There’s no need to worry about musty-smelling clothes
even if they remain unused for a long period.
- Makes Shapeless Garments a
Thing of the Past
High temperatures and harsh bleaches can damage and discolor your clothes.
The Ag+ Silver (Nano) Technology helps your clothes last longer, without
stretching, shrinking, pilling or fading.
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.
