What Does the 4C Error Mean?
The Samsung washer 4C error code indicates a water supply problem. This means the washer is not filling with water properly or is taking too long to fill during the wash cycle.
On some Samsung washer models, similar water supply errors may appear as 4E or nF.
Common Causes of the Samsung 4C Error
Several issues can trigger the 4C error code, including:
- Water supply valves turned off
- Low household water pressure
- Kinked or blocked inlet hoses
- Clogged inlet filter screens
- Faulty water inlet valve
- Frozen water lines
- Wiring or control board problems
How To Fix Samsung Washer 4C Error
Follow these troubleshooting steps to help diagnose and fix the 4C error code.
1. Check the Water Supply
Make sure both hot and cold water supply valves are fully turned on.
2. Inspect the Inlet Hoses
Check the water inlet hoses behind the washer for:
- kinks
- bends
- pinched sections
- leaks
Straighten or replace damaged hoses if necessary.
3. Clean the Inlet Filter Screens
Turn off the water supply and disconnect the hoses from the washer.
Inspect the small inlet filter screens for:
- sediment
- mineral buildup
- debris
Clean the screens gently before reconnecting the hoses.
4. Check Household Water Pressure
Low water pressure can prevent the washer from filling correctly.
Verify that nearby faucets have normal water flow.
5. Restart the Washer
Reconnect everything, turn the water supply back on, and run a short wash cycle to see if the error returns.
6. Inspect the Water Inlet Valve
If the washer still does not fill properly, the inlet valve may be faulty and require replacement.
How To Reset Samsung Washer After 4C Error
You can often reset the washer using these steps:
- Turn off the washer.
- Unplug the washer from power.
- Wait approximately 5 minutes.
- Plug the washer back in.
- Turn the washer on.
- Start a short wash cycle.
Some Samsung washer models may use slightly different reset procedures.
