Eco BubbleTM
Description
Before the normal cycle begins, the unique bubble generator starts working.
It helps dissolve and activate the detergent using air and water to generate bubbles that
penetrate faster and more evenly throughout the wash load. This brings the detergent into
contact with each fiber in the load.
※ Based on internal bench top test water temp.15℃, IEC60456 EU standard detergent, grease soil swatch (EMPA120).

2. Safety Instruction
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 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.
WARNING
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.

• Sharing a wall socket with other appliances using a power strip or extending the power cord may result in electric
shock or fire.
• Ensure that the power voltage, frequency, and current are the same as those of the product specifications.
Failure to do so may result in electric shock or fire. Plug the power plug into the wall socket firmly.
Remove all foreign substances such as dust or water from the power plug terminals and contact points using a dry cloth
on a regular basis.
• Unplug the power plug and clean it with a dry cloth.
• Failure to do so may result in electric shock or fire.
Plug the power plug into the wall socket so that the cord is running towards the floor.
• If you plug the power plug into the socket in the opposite direction, the electric wires within the cable may be damaged
and this may result in electric shock or fire.

4. Installation
4-4. Installation Requirements
■ Flooring
For best performance, the washing machine must be installed on a solid floor. Wood floors may need to be reinforced to
minimize vibration and/or unbalanced loads. Carpeting and soft tile surfaces are not a good resistance to vibrations and
may cause the washing machine to move slightly during the spin cycle.
CAUTION: Do NOT install the washing machine on a platform or a poorly supported structure.
Install your appliance on a solid, level floor that can support its weight.
■ Alcove or closet installation
To operate safely and properly, your new washing machine requires the following minimum clearances:
Sides
25 mm
Top
25 mm
Rear
50 mm
Front
550 mm
If both the washing machine and a dryer are installed in the same location, the front of the alcove or closet must have at
least a 550 mm unobstructed air opening. Your washing machine alone does not require a specific air opening.
