Samsung Washer Error Code 4C / 4E / nF: What It Means and How to Fix It
Seeing 4C / 4E / nF on your Samsung washer? Here is what Samsung says it means, the checks you can safely do yourself, and when to call a technician.
What Does Samsung 4C / 4E / nF Mean?
A 4C, 4E or nF code means your Samsung washer isn’t filling with water correctly. Samsung points first to the water supply: hoses, valves and the small filters where the hoses connect.

What Causes Samsung 4C / 4E / nF?
These are the causes Samsung lists and the parts a technician checks.
How to Fix Samsung 4C / 4E / nF
Try these steps in order. Unplug the appliance or switch off the breaker before reaching inside or removing panels.
Check the supply valves and hoses
Make sure the hot and cold valves behind the washer are fully open, the hoses aren’t kinked, and each hose goes to the matching inlet.
Check the drain hose
Make sure the drain hose isn’t kinked or pushed too far down the drain pipe, which can siphon water out while the washer fills.
Reset the washer
Unplug the washer or switch off its breaker for about a minute, then restore power and try again.
Clean the inlet filters
Turn off the water, disconnect the inlet hoses at the washer and clear any debris from the small filter screens, then reconnect them.
When to Call a Technician
Schedule a repair if:
- The code returns with the valves open and filters clean
- Water enters very slowly or not at all
- You hear the valve hum but no water flows
- The washer overfills or shows other codes

Yes. Samsung lists 4C, 4E and nF together as water supply codes. Which one appears depends on the model.
Yes. Partly closed valves, clogged filter screens or low household water pressure can all keep the washer from filling in time.
