Samsung Washer 4C Error Code

Washer is not filling with water. What it means, which models show it, and how to clear it, easiest fix first.

SamsungAll Samsung washer codes

4C
Easy DIY fix

The washer is not getting enough water in the time it expects, so it stops the cycle. The usual culprits are supply valves that are partly closed, kinked or frozen fill hoses, clogged inlet screens, or low household water pressure. A failed water inlet valve is the most common part failure behind this code.

Compatible models

Samsung doesn't publish a model list for this code; it appears on Samsung washers with a digital display. Check your owner's manual.

Also shown as

Also shown as 4E, nF, or 1 4C depending on the model and display. Do not confuse it with 4C2, 4E2, or nF1, which on most models mean the hot and cold hoses are reversed (some top-load models use nF1 as a general water supply error, so check your manual).

Difficulty

Most people can clear this one at home with simple checks.

Safety first: unplug the washer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung 4C

  1. Open both supply valves fully

    Find the hot and cold faucets behind the washer and turn each one counterclockwise until it stops. Make sure the hot hose goes to the hot inlet and the cold hose to the cold inlet, and that neither hose is pinched behind the machine.

  2. Check the drain hose position

    Samsung recommends the drain hose go 6 to 8 inches into the standpipe, no deeper. A hose pushed in too far can siphon water out while the washer is filling, which can trigger a fill error. Samsung also advises against Flood Safe-style supply hoses, so swap them for standard fill hoses if you have them.

  3. Reset the power

    Turn the washer off, then unplug it or switch off its circuit breaker for about 2 to 3 minutes. Restore power and start a new cycle. A one-time glitch often clears this way, so note whether the code comes back.

  4. Clean the inlet screens

    Shut off both faucets, unplug the washer, and keep a towel and bucket handy. Unscrew the fill hoses from the back of the washer and gently remove any grit or mineral buildup from the small mesh screens at the inlets using needle-nose pliers or a soft brush. Reattach the hoses hand-tight plus a quarter turn, then turn the water back on and check for leaks.

When to call a technician

If the faucets are open, water pressure is normal, and the screens are clear but the code returns, the water inlet valve or control board likely needs testing and replacement by a technician.
