2. Operation for each button Button Operation Power 1. M icro switch type is used to meet the 0.5W of standby power consumption requirement. • Tact switch type is used for other regions that do not have 0.5W requirement. (D16 setting of F-PCB; D16 connected ➔ Tact SW, D16 disconnected ➔ Encoder SW) 2. When the “Power” button is pressed, the power supply relay is engaged and “---” will be shown on the display. 3. All other LEDs are off. 4. Automatic power off function: 5.

3. Error displays and causes of errors Error display Details • This error occurs when the water level sensor frequency is over 30 KHz or below 15 KHz and also when the frequency is increased suddenly by more than 1.44 KHz in four seconds after filling up water. ➔ Water level sensor hose is off the position.
■ Errors related to the motor Error display Details E5 High voltage error E6 IPM Fault error E7 Motor hall sensor error E8 Motor operation overloading error This error occurs when there is no next hall sensor input within 320 msec due to overloading of the motor. b1 Motor alignment error This error occurs when the alignment of the motor at the initial stage of motor operation is against the logic.
4. Various test modes 4-1. Electronic device operation test mode 1) Procedure to enter the test mode - Press the Wash button three times while pressing the Water+ (water level) button in the initial state. 2) Operation procedure - Use the Soak button to test various devices. No.
4-2. Spin discharge test mode 1) How to enter - In the initial condition, press the rinsing button three times while holding down the water level button. 2) Control procedures - Using the spin dry button select the target RPM. (300 ~ 800RPM: steps of 20RPM) - Press the start/pause button to start spin drying. 3) The current RPM is displayed during operation. When it stops the target RPM is displayed. 4-3.
5. Troubleshooting Symptom Items to check Resolution • Check the power supply voltage • Check the power loss or circuit breaker Check the power supply Washing machine is not turned on. Check whether the fuse is blown ➡ • Replace the fuse and check the operation in the test mode to see whether the fuse is blown again • If the fuse is blown during water filling, measure the resistance of water supply valve and replace it if it is shorted.
Symptom Tub turning during washing Items to check Resolution • Remove any alien substances between the lever clutch and the link valve drain. Open the door and check if the tub is rotating. • Disassemble the rotor and check the clutch and any damage in the coupling. • Replace the spring lift. Water is continuously filled up even when the machine is turned off. Water supply is not turned off Water draining does not work After reaching the HIGH level, water supply continues.
Symptom Lamp is not turned on. Items to check Resolution • Check the failure of the lamp. • Replace the lamp • Check the contact status of connector and terminals • Replace the PCB. Check the levelness of the set. • Adjust the levelness. Check deformation of the safety lever. • Replace the safety lever. Check if the sync motor wire is tight. • Replace the sync motor. Check for alien substances in the discharge valve bellows. • Remove alien substances.
