A dishwasher appliance includes a wash tub that defines a wash chamber, a sump for collecting wash fluid, a pump assembly for selectively urging a flow of the wash fluid from the sump, a microphone for monitoring sound generated during operation of the dishwasher appliance, and a controller in operative communication with the pump assembly and the microphone. The controller is configured to energize the pump assembly, obtain a sound signal generated during energization of the pump assembly, determine that the pump assembly has experienced an arcing event based at least in part on the sound signal, and implement a responsive action in response to determining that the pump assembly has experienced the arcing event based at least in part on the sound signal.
