Samsung Washing Machine Error Code 4C
The washer is not filling with water, or is filling too slowly. This is a supply-side problem: the machine is fine, but water is not reaching it at the expected rate.
Also shown as: 4E, E1, nF
Common causes
- Water taps not fully open
- Inlet hose kinked or crushed
- Mesh filter in the inlet valve clogged with grit
- Water pressure too low
- Frozen taps or hoses in winter
What to check, in order
- Open both the cold and hot water taps fully.
- Straighten the inlet hoses and check nothing heavy is resting on them.
- Unscrew the inlet hoses and clean the small mesh filters inside the valve connections.
- Confirm other taps in the home have normal pressure.
- If the code appeared in freezing weather, thaw the taps and hoses before retrying.
Clear the code and test
- Fix what the checks above found first — a filter cleaned, a hose straightened, taps opened. Clearing the code without fixing the cause only brings it back.
- Close the door, plug the machine back in and restore the water supply.
- Run a short rinse and spin, or the shortest wash programme, and watch the stage where the code appeared before (filling, washing, draining or spinning).
- If the cycle finishes with no code, the fault is cleared. If the code returns at the same stage, write down the code and that stage before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code 4C, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
