Fault codes were always for the technicians, just as they are to car mechanics, as being a service aid, not a replacement for the technician's diagnostic skills. The fault code comes up when the appliance encounters some form of error that it can detect, often a blinking series of lights or a code displayed in the LCD or LED display indicates the nature of the fault, what it does not do generally is pinpoint the actual failure or the failed component that has caused the alarm.

For example the ever popular E2 error code on dishwashers can be caused by no less than twelve different failures, all that code has done is tell the technician a general area to start looking in.
