Abstract
A home appliance diagnostic system and method are disclosed. A home appliance outputs product information in the form of a sound signal, which is transmitted to a service center at a remote site over a communication network so that the service center can readily check the state of the home appliance. The home appliance performs a sound signal re-output operation in such a manner that it re-outputs the same product information in the form of a different sound signal. Therefore, it is possible to improve a sound recognition rate, so as to improve fault diagnosis accuracy.
