Abstract
A home appliance, such as a laundry washing machine or refrigerator including a buzzer designed to sound an alarm or provide an audible indication of a certain condition is disclosed. The appliance may transmit information (such as diagnostic or fault codes and appliance usage information) to a remote service center without the need for a physical connection to a telephone line. The buzzer may be controlled to produce audible tones in a predetermined format which can be transmitted from the appliance, through the air and down a telephone line through a telephone handset to the service center. The signal is recorded at the service center and the data extracted. The data is then analyzed to obtain the fault and/or usage information.
