Some people have reported that their Samsung washer still shows a 4C error when the drum is full of water. This happens when there is an issue with the control board of the washer, or the water level and pressure detecting sensors are faulty.

However, fixing this error is simple. If every hardware seems clean and fine, you should reset the unit as sometimes a small software glitch can mistakenly lead the washer to represent an error message.
