Our washer kept throwing the "dc" code every time we had any sort of load. After doing some research I found that the dampers will go out and cause the washer to be unable to keep a balanced load. I replaced these by removing four screws that hold the top of the washer in place, then balance it up in the air while I just removed the original dampers by hand. It probably took around 20 minutes total and saved me the cost of having a repair service come out.
