What error code 4C means on a Samsung washer

Water is not entering the washer correctly. [1]

This is a water fill code. Codes and wording can vary by model, so check your owner's manual for your model number.

How to fix Samsung washer error code 4C (safe owner checks)

Safety first: disconnect power before you remove any panel or reach into the sump or drum. Do not touch wiring, the control board or the motor. If you see water near electrical parts, stop and call a technician. These steps are based on Samsung's published guidance [1], rewritten for clarity.

Check the hoses. Make sure hot goes to hot and cold to cold, and the hoses aren't bent or kinked. Samsung says not to use Flood Safe hoses.
Open the valves. Open both water valves fully and leave them open while the washer runs.
Check the drain hose. Make sure it isn't kinked and goes 6–8 in into the drain pipe.
Reset. Unplug the washer or switch off its breaker for 1 minute, then try a cycle.
Clean the inlet filters. Turn off the valves, disconnect the hoses and clean any debris from the inlet filters.
