    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...
  • 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 electrical hazard.. • When connecting wires, make sure to connect them using the relevant connectors and check that they are completely properly. 4 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. 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 no wire touches a rotating part or a sharpened part of the electrical harness. • 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 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 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. 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. Safety Instructions _ 3...
  • Page 6 CAUTION AFTER SERVICING • Check the assembled status of the parts. 4 Now is a good time to inspect your work. Review all connections and wiring, including mounting hardware. • 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 the floor with respect to the original position of the washing machine prior to service. By doing this now will reduce for the need of customer dissatisfaction and redo call. 4 Vibrations can shorten the lifetime of the product. 4 _ Safety Instructions...

  • Page 26 For USA Error Type Causes Remarks - Check the consumer’s power conditions. : Make sure to check the operating voltage. Connect a tester to the internal power terminals during the Boil or Dry operations and observe the washing machine’s operation carefully. High/Low Voltage Detected ERROR! : Check the voltages. (An error occurs when under or over voltage is supplied.) : Check whether a plug receptacle is used. When the connecting wire is 1m, a momentary low voltage may drop up to 10 V Power Error - Main PBA fault (sometimes) - This error is not a fault but occurs during a momentary power failure : When this error code is displayed, the operation restarts from the cycle that was stopped due to the power failure. : If the washing machine is not operating and this error code is displayed, it is displayed to notify that a power failure has occurred. - The signals between the sub and main PBAs are not sensed because of commuication error.
  • Page 27 For USA Error Type Causes Remarks - The washing heater is short-circuited or has a wire disconnected. - The washing heater in the tub has an error. (Contact If the heater has error, temperature sensor fault) no error, this - If the water level sensor operates without water occurs because because water is frozen or for any other reason and of a PBA relay the temperature sensor engaged at the bottom to malfunction. prevent overheating for the washing heater detects a temperature of 100 to 150 ˚C, the washing machine turns the input power off. - This error occurs when the red temperature sensor ERROR! Water Temperature Control Heater Error (Heater Problem at the center of the dry heater operates (at a Relay) temperature higher than 145 ˚C) : Corrective action – Press the button at the center lightly. The washing machine will operate normally. Alternatively, replace the temperature sensor if the temperature sensing is unstable because of functional degradation.
  • Page 28 For USA Error Type Causes Remarks - As laundry causes this error, check the laundry. Unbalance Unbalanced load ERROR! - Find the reason for the unbalance and solve it as Error directed in the user manual. - This occurs when too much foaming is detected. It is also displayed while foaming is removed. When the removal is finished, the normal cycle proceeds. “Sud” Foaming or “SUdS” is displayed when too much foaming is Excessive Suds ERROR! SUdS Detected detected and “End” is displayed when the removal of the foaming is finished. (This is one of the normal operations. It is an error for preventing non-sensing faults.) - Error detected in the Mems PBA or data error detected. Check the wire connections. ERROR! Front MEMS Sensor Problem Replace if necessary.
