What does the 5C error code mean and how do I fix it?

The 5C error code means water is not draining from the machine. Check that the drain hose is not frozen, clogged, or kinked, and that it is positioned and straightened correctly all the way to the drain system. Also clean the debris filter as it may be clogged. If the code remains after these steps, contact a Samsung service centre. (Page 48)
