Error codeAC6 Electronic lockout
ApplianceDishwasher
Quick answer
AC6 on a Samsung dishwasher means it is electronically locked out: it switches on but will not start or continue a cycle.
Model compatibility: Samsung reuses codes across series and model years, so AC6 Electronic lockout may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Electronically locked out: switches on but will not start or continue a cycle.
AC6 on a Samsung dishwasher means the machine is electronically locked out. It switches on, and the control panel may light up, but pressing Start does nothing and no cycle starts or continues. It is listed for current dishwashers.
Discharge it fully
Power the dishwasher off at the breaker, or unplug it, for 10 minutes so it discharges fully. Then power it back on and try starting a cycle.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
