    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 BEFORE SERvICING...
  • Page 4 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 completely 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. 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. • Do not allow consumers to repair or service any part of the washing machine themselves. 4 This may result in personal injury and shorten the product lifetime.
  • Page 5 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 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 water (rain drops). 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 cause damage to the product. Safety Instructions _ 3...
  • Page 6 CAUTION AFTER SERvICING • Ensure that all components are reassembled correctly and are safe before connecting the appliance to the mains supplies. • Check the insulation resistance. 4 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 • Check whether the washing machine is level in relationship with the floor. Check whether it is installed firmly on the floor. 4 Vibrations can shorten the lifetime of the product. 4 _ Safety Instructions...

    2. FEATURES AND SPECIFICATIONS 2-1. CONCEPT ■ COMMON FEATURES Features Description Crystal Gloss Design • Even the buttons, which respond to the slightest touch of the fingertip, were carefully designed to enhance the look of the machine’s immaculate exterior. Complementing the washer’s organic design is the wide display, featuring the Ice Blue LED, which is clean and simple yet a premium feel. Smart Check • Smart Check, an automatic error-monitoring system. It detects and diagnoses problems at an early stage and provides quick and easy troubleshooting solutions using a smartphone App. So it saves your time having to find the manual and avoids the cost and inconvenience of unnecessary engineer callouts – and potentially expensive repair bills. ※ You must first download the Samsung Smart Washer at the Play Store or the App Store, and install it on a mobile device featuring the camera operation. The Smart Check function has been optimized for : Galaxy & iPhone series. (applicable models only) Features and Specifications _ 5...
  • Page 8 Features Description Eco Bubble • 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. C, IEC60456 EU standard detergent, ○ ※ Based on internal bench top test water temp.15 grease soil swatch (EMPA120). Bubble Soak • With the simple touch of a button the Samsung washing machine’s Bubble Soak technology helps remove a wide variety of normally stubborn stains. It adds an extra phase to a normal washing cycle in which clothes are thoroughly soaked in active bubbles, so any dirt and stains are loosened and can be removed much more effectively. 6 _ Features and Specifications...
