The Samsung Washer 4C Code usually means the washer is not receiving enough water during the fill cycle. When the machine cannot reach the expected water level within a specific time, it stops the cycle and displays the 4C error code.
In most cases, the problem is related to the water supply rather than a major component failure. Closed water valves, clogged inlet screens, bent hoses, and low household water pressure are among the most common causes.

Quick Answer: What Does Samsung Washer 4C Code Mean?
On most Samsung washing machines, the 4C code indicates a water supply problem. The washer is either receiving too little water or taking too long to fill.
Unlike the Samsung Washer 5C Code, which is related to drainage problems, the 4C code specifically focuses on incoming water flow.
Most Common Causes of Samsung Washer 4C Code
- Water supply valves are closed
- Inlet hoses are bent or kinked
- Clogged inlet filter screens
- Low household water pressure
- Faulty water inlet valve
- Control board or wiring issue
Symptoms That Often Accompany a 4C Error
- The cycle stops shortly after starting
- The tub fills very slowly
- No water enters the drum
- The machine hums but does not fill
- The display repeatedly shows 4C
- The cycle times out before washing begins
These symptoms generally indicate a water-supply restriction.
How to Fix Samsung Washer 4C Code
1. Check the Water Supply Valves
Make sure both hot and cold water valves behind the washer are fully open.
2. Inspect the Inlet Hoses
Look for kinks, twists, crushing, or restrictions that may reduce water flow.
3. Clean the Inlet Filter Screens
Samsung washers use small mesh screens where the hoses connect to the machine. Mineral deposits and sediment can gradually reduce water flow.
4. Verify Household Water Pressure
If nearby faucets also have weak pressure, the issue may be related to the home’s plumbing rather than the washer itself.
DIY Repair Cost Guide for Samsung Washer 4C Code
| Repair Step | Estimated Cost |
|---|---|
| Open Water Supply Valves | $0 |
| Straighten Inlet Hoses | $0 |
| Clean Inlet Filter Screens | $0 |
| Replace Water Inlet Valve | $20 – $50 |
| Professional Diagnosis | $75 – $150 |
Most Samsung 4C errors can be fixed without replacing any parts.
How to Reset a Samsung Washer After a 4C Error
- Turn the washer off.
- Unplug it from power.
- Wait about 5 minutes.
- Plug it back in.
- Start a short cycle.
A reset can clear temporary electronic glitches but will not fix a blocked hose or faulty valve.
When the Samsung Washer 4C Code Keeps Coming Back
If the code returns after checking the water supply, the issue may involve:
- Faulty water inlet valve
- Damaged wiring
- Control board malfunction
- Persistent low water pressure
- Model-specific fill system fault
If your washer appears to be taking in too much water instead of too little, compare the symptoms with the Samsung Washer OC Code, which is associated with overflow conditions.
If the washer fills normally but cannot drain, review the Samsung Washer 5C Code guide instead.

Final Thoughts
The Samsung Washer 4C Code almost always points to a water-supply problem. Before assuming the washer needs repair, check the water valves, inlet hoses, filter screens, and household water pressure.
Most users can resolve the issue without replacing parts. If the code continues to return after basic troubleshooting, further diagnosis of the inlet valve, wiring, or control system may be necessary.
