Use this function if you need an accurate diagnosis by an LG Electronics service centre when the product malfunctions or fails. Use this function only to contact the service representative, not during normal operation.

When instructed to do so by the call centre, hold the mouthpiece of your phone over the Smart Diagnosis™ logo on the controller.




With the door closed, press and continue to hold the STOP/Cancel button for 3 seconds so that 'Loc' appears on the display. Continue to hold the STOP/Cancel button for a further 5 seconds until '5' appears in the display. (so, the STOP/Cancel button will need to be held for 8 seconds continuously). A tone will then emit from behind the Smart Diagnosis symbol.


Keep the phone in place until the tone transmission has finished. The display will count down the time.


Once the countdown is over and the tones have stopped, resume your conversation with the call center agent, who will then be able to assist you in using the information transmitted for analysis.
