Dishwasher Won't Start

Why a Dishwasher Won't Start

A dishwasher that won't start despite power to the outlet usually points to one of a few specific failures rather than a general electrical problem. A failed door latch switch is the most frequent cause, since most dishwashers refuse to run unless the control board senses the door is fully latched and locked. A tripped control board can lock out the cycle after detecting an internal fault, showing no response to any button press. A blown thermal fuse, installed as a safety cutoff against overheating, cuts power to the unit entirely and requires replacement before it runs again. Sometimes the fix is simpler: an engaged child lock disables the control panel and is easy to overlook, especially on models where the lock icon is small or unlabeled. Distinguishing between these causes usually just takes testing the door latch and checking for stored fault codes.
