Samsung Washing Machine Error Code 4C2
The washer detected water that is too hot on the cold supply. In almost every case the hot and cold hoses have been connected to the wrong taps.
Also shown as: 4E2, CE
Common causes
- Hot and cold inlet hoses swapped at installation
- Cold tap connected to a hot water line
- Very hot water supply on the cold line
What to check, in order
- Check that the cold hose runs to the cold tap and the hot hose to the hot tap.
- Feel both hoses during a fill: the cold hose should stay cold.
- Swap the hoses if they are reversed, then run a short rinse cycle.
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 4C2, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
Parts that may be involved
Inlet hose
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.
