DC error code means: "Unbalanced load". It can occur if the washer:
1. is overloaded (too many clothes inserted),
2. can't balance the load within a few balance cycles,
3. has a damaged balance sensor,
4. isn't regulated properly (vibrates abnormally).
IMHO you just overloaded the washer :)

Product: Home Appliances > Washers & Dryers > Washers > WF218ANW
dc = Unbalanced load prevented the washer from spinning.

Check for blockage in toner supply ,located at rear of hopper. Also is the toner ok
