Samsung 4C Error Code
4C (shown as 4E on older Samsung washers) is a water-supply fault: the washer isn't getting the water it expects. Usually it's a closed tap, a kinked hose or a clogged inlet screen — rarely the valve itself.
4C
Means: Water supply error — the washer isn't filling with enough water in the expected time (older models show 4E).
Fix: Check both supply taps are fully open, straighten the fill hoses, and clean the mesh inlet filters where the hoses meet the machine.
What causes a Samsung 4C
The washer times the fill; if the water level doesn't rise fast enough, it stops and shows 4C. Common causes:
- Supply tap partly or fully closed: the most common and easiest to miss.
- Kinked or crushed fill hose: behind the machine or under the tap.
- Clogged inlet mesh filters: the little screens inside the hose connectors catch grit and rust.
- Low household water pressure: if pressure is weak, the fill times out.
- Faulty water inlet valve: if everything upstream is fine, the valve solenoid may have failed.
Step-by-step fix
- Turn off the washer. Check both hot and cold taps are open all the way.
- Pull the machine out and straighten the fill hoses — no kinks or tight bends.
- Turn off the taps, unscrew the hoses at the machine end, and pull out the small mesh filters with pliers. Rinse them, clear any debris, and refit.
- Reconnect, open the taps, and run a rinse cycle to confirm the machine fills normally.
- If it still shows 4C, test water pressure by filling a bucket from the tap — a slow fill points to a plumbing issue, not the washer.
When to call a technician
If the taps, hoses and filters are all fine and pressure is good, the water inlet valve or the wiring to it likely needs replacing. That's a straightforward part but requires opening the machine.
FAQ
Is 4C the same as 4E on Samsung washers?
Yes. Newer Samsung washers display 4C for a water-supply fault; older ones show 4E. Both mean the same thing and are fixed the same way.
Why does my Samsung washer say 4C when the water is on?
Even with the taps open, a kinked hose, a clogged inlet mesh filter, or low water pressure can stop the machine filling fast enough. Clean the filters and check pressure before suspecting the valve.
Can 4C be caused by the cold tap only?
Yes — most cycles draw cold water, so a closed or restricted cold supply alone will trigger 4C even if the hot side is fine.
