LG Washer Dryer - What should I do to avoid electricity shocks from touching a dryer

What should I do to avoid electricity shocks from touching a dryer?

  Cause

        -  If you feel a weak electric shock when you touch a dryer, it is likely to be static electricity.

           Static electricity usually occurs in dry weather.

         - You may feel a weak electric shock due to electric current that flows along the exterior of dryer or hand grip
           in humid weather, particularly in summer.

  How to fix

          - Please check if a power outlet that power cord is plugged is grounded. 
    
          - If the power outlet is grounded, flip the power cord and try plugging back in.
 

          - If you still feel electricity even when the power outlet is grounded and power cord is properly connected,
           contact the service center.
