,1. Safety instructions
1-1. Safety instructions for service engineers
► Be sure to observe the following instructions to operate the product correctly and safely to 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 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 electric shock or fire due to lightning.
• 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.
Safety Instructions _ 1
, WARNING 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 electrical hazard..
• When connecting wires, make sure to connect them using the relevant connectors and check that they are
completely properly.
√ If tape is used 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.
WARNING AFTER SERVICING
• 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.
• If it seems that grounding is needed due to water or moisture, make sure to run
grounding wires. Grounding
(Check the grounding of the power outlet, and additionally ground it to a metallic water terminal
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.
