Abstract
A system and method of communicating information associated with an appliance is provided. An appliance can present an optical machine-readable representation, such as a linear or matrix barcode, on a display of the appliance. The optical machine-readable representation can encode information associated with an event occurrence for the appliance. A client, such as a computer, smartphone, tablet, etc., can capture information indicative of the optical machine-readable representation. The client computing device can then access information, such as diagnostic information, responsive to the optical machine-readable representation.
