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

► Following the repair by a non-authorised service provider, self-repair or non-professional repair of the product, Samsung is not
liable for any damage to the product, any injury or any other product safety issue caused by any attempt to repair the product
which does not carefully follow these repair and maintenance instructions. Any damage to the product caused by an attempt to
repair the product by any person other than a Samsung certified service provider will not be covered by the warranty.

WARNING BEFORE SERVICING

• (When servicing electrical parts or harnesses) Make sure to disconnect the power plug before servicing.
4 Failing to do so may result in a risk of electric shock.

• Advise consumers not to connect several appliances to a single power outlet at the same time.
4 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.
4 Failing to do so may damage the plug or power outlet 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.
4 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.
4 There is a risk of explosion and fire caused from electric sparks.

Safety Instructions _ 1
 This Document can not be used without Samsung’s authorization.

WARNING WHILE SERVICING

• Check if the power plug and outlet are damaged, flattened, cut or otherwise degraded.
4 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.
4 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 properly connected.
4 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.
4 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.
4 If not inserted into the bracket-heater, it touches the drum and causes noise and electric leakage.

• Do not repair the washing machine without safety gloves.

4 It can cause injury.

WARNING AFTER SERVICING

• Check the wiring.

4 Ensure that the wiring can not be damaged by any sharp edges or moving parts.

• Check for any water leakage.

4 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.

• Advise consumers not to repair or service any part of the washing machine themselves.
4 This may result in personal injury and shorten the product lifetime.

2 _ Safety Instructions
 This Document can not be used without Samsung’s authorization.

CAUTION BEFORE SERVICING

• Do not sprinkle water onto the washing machine directly when cleaning it.
4 This may result in electric shock or fire, and may shorten the product lifetime.

• Do not place any containers with water or any other liquid on the washing machine
4 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.

4 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.

4 This may result in electric shock or damage to the product.

CAUTION WHILE SERVICING

• When wiring a harness, make sure to seal it completely so no liquid can enter.
4 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.
4 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.
4 Do not lay it down on its front. This may result in the inside tub damaging parts.

• At least two people should work when working with heavy products
