For appliances with the c or d logo Use the Smart DiagnosisTM feature in the ThinQ application for help diagnosing issues with the appliance without the assistance of the LG Customer Information Center. Follow the instructions in the ThinQ application to perform a Smart DiagnosisTM using your smartphone.
Smart DiagnosisTM cannot be activated unless the appliance can be turned on using the Power button. If the appliance cannot be turned on, troubleshooting must be done without using Smart DiagnosisTM.
