LG ThinQ-enabled washers connect to the LG ThinQ app via Wi-Fi for smart diagnosis, remote monitoring, and cycle downloads. ThinQ-specific features: Smart Diagnosis uses the washer's speaker to transmit diagnostic data to the LG app - hold the phone microphone to the speaker and press the Smart Diagnosis button. The app decodes the sounds into specific error codes and repair suggestions. ThinQ washers can also send push notifications when a cycle is complete or when an error occurs. Wi-Fi connection issues (washer goes offline in the app) are the most common ThinQ complaint and are NOT a washer fault - check your router, update the app, or re-pair the washer in ThinQ settings. LG ThinQ does not change the underlying washer operation - all error codes (LE, OE, UE, etc.) are the same as non-ThinQ LG washers.
