The 4C error on a Samsung washer indicates a water supply issue—specifically, that the washing machine is not receiving enough water, or water is not entering the machine at all. This error typically appears at the start of a wash cycle or during the rinse phase, when the washer expects to fill with water but detects a problem.
Common Causes of the 4C Error
- Water Supply Taps Closed or Partially Open
- If the water faucets (hot and/or cold) supplying the washer are closed or not fully open, water cannot flow into the machine.
- Blocked or Kinked Water Inlet Hoses
- The hoses connecting your washer to the water supply may be bent, pinched, or blocked, restricting water flow.
- Clogged Water Inlet Filters
- Small filters at the ends of the inlet hoses or inside the washer where the hoses connect can become clogged with dirt or mineral deposits.
- Low Water Pressure
- If the water pressure in your home is too low, the washer will not be able to fill up in the expected time.
- Faulty Water Inlet Valve
- The valve controlling water entry into the washer may be malfunctioning and not opening properly.
- Incorrect Hose Connection
- The hoses may be connected to the wrong water taps or not connected securely.
How to Troubleshoot and Fix the 4C Error
- Check Water Taps
- Make sure the taps supplying water to the washer are fully open.
- Inspect Inlet Hoses
- Check both the hot and cold water hoses for kinks or bends. Straighten them if needed.
- Disconnect the hoses and ensure they are not clogged. Run water through the hoses to check for blockages.
- Clean Inlet Filters
- Turn off the water and disconnect the hoses from the washer.
- Look for small mesh filters at the washer’s water inlets. Remove and gently clean them with a brush.
- Check Water Pressure
- Ensure that your home’s water pressure is within the washer’s required range (usually 0.5–8 bar, but check your manual).
- Inspect the Inlet Valve
- If the above steps do not resolve the issue, the inlet valve may be faulty and require professional repair or replacement.
- Ensure Correct Installation
- Double-check that the hoses are properly connected to the correct hot/cold inlets both on the machine and to your water supply.
Additional Tips
- If you recently moved the washer or installed it, double-check all connections.
- The 4C error can also appear as 4E on some Samsung models—these are the same error.
If the error persists after performing these checks, you may need to contact Samsung customer support or a qualified appliance technician for further assistance.
