Smart Diagnosis - Washing Machine


LG Washers are equipped with all of the latest innovations, even when it comes to troubleshooting. Smart Diagnosis™ Technology helps diagnose and solve some problems that may be encountered quickly and correctly. The Smart Diagnosis feature is available in the LG SmartThinQ App.

Smart Diagnosis

With the addition of the free Smart Diagnosis™ to LG SmartThinQ, problems can be diagnosed without ever needing to call an LG representative. This application can record and analyze the special tones emitted by Smart Diagnosis™ washers and can instantly provide troubleshooting steps to get the problem fixed.

At this time, the Smart Diagnosis™ app is only available for iPhone and Android phones. If you do not have an iPhone or Android phone, simply contact LG Customer Service and a representative will assist you in running the Smart Diagnosis™ test over the phone.
