What we can confirm
Code AC, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
AC
The machine has more than one electronic board in it and they have stopped agreeing. On a front loader that is usually the main board and the panel; on machines with an inverter it can be the motor drive as well. Connections are the first suspect and they are the cheap one, which is why this is worth diagnosing rather than replacing on.

What else belongs to the washers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Water where it should not be, or a level sensor that cannot agree with itself
Water is not arriving at the rate the machine expects
The cold inlet is being fed hot water
The water is not leaving, or not leaving fast enough
More water in the drum than the cycle called for
The panel thinks a button is being held down
The supply is not what the machine expects
The door is not being seen as shut and locked
The dispenser drawer is not fully closed
Too much foam, and the machine is waiting for it to collapse
The small add-laundry door is not latched
The drum cannot be spun safely with the load as it sits

About Samsung washer error code AC
What AC means on this make
The machine has more than one electronic board in it and they have stopped agreeing. On a front loader that is usually the main board and the panel; on machines with an inverter it can be the motor drive as well. Connections are the first suspect and they are the cheap one, which is why this is worth diagnosing rather than replacing on.

Samsung publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with. They mean the same thing and they are one page here, so whichever of them you searched for, this is the right page.
Where this appears, and why not to clear it
On the appliance's own display. Samsung reports errors two ways: machines with a digital display show a code, and the same machines without one blink their cycle lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power — Samsung asks for this itself on its refrigerator and dishwasher pages, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.
What to do about it
- Switch the washer off for two to three minutes, power it back on and restart the cycle. Samsung publishes no procedure beyond this for these conditions, and neither will we.
- Note whether the code returns immediately or only during a particular part of the cycle. That single observation narrows it more than anything else you can do.
- If it returns, this is a measured diagnosis rather than a part swap, and it is what a diagnostic visit is for.
Where this goes next
The job this usually becomes is appliance control board repair, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 506-1256 and describe what the panel is doing before booking anything.
