Below information is prepared for exact trouble diagnosis and suitable repair guide. Caution for the Repair and Replacement Please follow below instruction for the trouble diagnosis and parts replacement.
6-1. TROUBLE DIAGNOSIS WARNING To avoid risk of electrical shock, personal injury or death, disconnect power to unit before servicing, unless testing requires power. Will Not Start • Plug the unit into the wall outlet. Check for proper voltage. • Check fuse or reset circuit breaker. • Push any key to turn on the washer and press the Start/Pause key to run the washer. • Close door and push the Start/Pause key to run the washer. • Check if washer is in a pause, soak or suds process.
6-1. TROUBLE DIAGNOSIS No Water Fill • Perform Quick Test Mode. Check all of Water Valves visually. (Pre Wash Valve, Cold Water Valve, Bleach Water Valve, Softener dispenses using Cold & Bleach Water Valve, and Hot Water Valve.) • Check if water taps are turned on fully. • Check Water Valves and Water Level Sensor (Refer to PCB Connector Check) • Check if there is any kink in inlet hoses. • Check if inlet screens are clogged up. • Check if water has enough pressure. If so, find out its contributors.
6-1. TROUBLE DIAGNOSIS Will Not Unlock • Check if the door is being pushed out, which may keep it from unlocking. • Door locks itself when the water level is too high. Opening door will result in water draining from door opening. • Check the following with Board Input Test Mode. Water Level (frequency): Over 23.80 KHz. → If so, refer to “Will Not Drain”. Temperature (Inside Drum): Higher than 60ºC/140ºC. → If so, wait until it drops. When everything is normal, check PCB connectors and Door Lock Switch.

13-2. AC Input & Power Circuit ▶ Function Generates a required DC power of 12V or 5V in case of supplied or disconnected AC power. ▶ Description - When AC 220V is applied to CN3, D17 D20 transforms it to DC 300V. - DC 300V is generated for the LVT1 secondary source by IC3 and PC1 turning on/off. - The secondary 12V depends on the ZD1 value.
13-3. Driving System Circuit ▶ Function Controls each driving system (VALVE, DOOR S/W, DRAIN-MOTOR) by turning RELAY or TRIAC on/off. ▶ Description - MICOM outputs a high signal of 5V from pin # 1 - 7 of IC7 and IC9. - Then, pin # 10 to 16 of IC7 and IC9 are electrically grounded (0V). - When pin # 10 to 16 are grounded, this creates an electric potential difference from the 12V that turns on RELAY 5,6,7 and TRIAC2,3,4,5.
13-4. Sensor Detection Circuit ▶ Function Detects signals from the sensor and controls the current system. ▶ Description - The water level sensor is connected to pin 4 of CN7. The frequency of the level sensor changes according to the water amount in the tub. Then, the frequency is input to MICOM pin 48 for detecting the water amount. The DHSEH sensor is connected to CN7 pin 5 and CN6 pins 3,4. The resistance of the temp. sensor changes according to the ambient temperature.
13-5. Silver Nano System ▶ Function Applies the electric current to the silver plate during the water supply and uses the silver water to perform the bacteria-free or sterilization processes. ▶ Description - Selects the silver nano feature to operate the system. - Supplies water to the two silver plates AG_B and AG_A. Then, SINAL_A and SIGNAL_B output a high signal of 5V. - Both SIGNAL_A and SIGNAL_B repeat this for 15 seconds outputting a high signal of 5V.
