How to Fix Samsung Washing Machine 4E Error
Last updated: 7 September 2026
Check the water supply, clean the inlet filter, and replace the inlet valve if faulty.
Overview
Samsung washing machine 4E error indicates a water supply fault. This guide covers diagnosing and fixing the 4E error.
Step-by-Step Fix
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- First, check that the water supply valves for the washing machine are fully open. These valves are usually located behind the appliance or under the sink. Turn them clockwise to open them fully if they are partially closed.
- Turn off the water supply and unplug the washing machine from the mains power supply. Disconnect the inlet hose from the back of the washing machine and check the mesh filter inside the hose connection for any debris or blockages.
- Clean the inlet filter by rinsing it under running water and using a small brush to remove any stubborn debris. Once the filter is clean, reattach the hose securely to the washing machine.
- Check the inlet hose for any kinks, twists, or damage that could be restricting water flow. Straighten any kinks and replace the hose if it is damaged. Ensure the hose is not trapped behind the machine when you push it back into place.
- Turn the water supply back on and plug the washing machine back into the mains power. Run a short cycle to test if the 4E error has cleared. If the error persists, the inlet valve may be faulty and need replacing.
- To test the inlet valve, you will need a multimeter set to resistance. Unplug the machine and remove the back panel to access the valve. Test the resistance of the valve coil. A reading between 200 and 500 ohms indicates the valve is functioning. An open circuit or very low resistance indicates a fault.
- If the inlet valve is faulty, it will need to be replaced. Purchase a replacement valve that is compatible with your washing machine model. Disconnect the old valve and install the new one, ensuring all connections are secure.
- After replacing the valve, run a short cycle to confirm that the 4E error has been resolved and the machine is filling with water correctly.
Common Error Codes
Review the common error codes and operating symptoms below to quickly identify the root cause of the fault before ordering replacement parts.
| Symptom / Code | Likely Root Cause | Recommended Resolution |
|---|---|---|
| 4E | Water supply fault | Check the water supply, clean the inlet filter, and check the inlet hose for kinks. If the error persists, the inlet valve may be faulty and need replacing. |
| 5E | Drain fault | Clean the drain filter and check the drain hose for blockages. This is a different error that may occur alongside 4E if water cannot drain properly. |
| DC | Door lock fault | Check the door lock mechanism. If the door is not latching correctly, the machine will not start. |
| UE | Unbalanced load | Redistribute the load in the drum. An unbalanced load can cause the machine to stop filling or spinning. |

How do I reset Samsung washing machine 4E error?
After fixing the water supply issue, turn off the washing machine at the mains for a few minutes, then turn it back on. The 4E error should clear. If it does not, there may still be an issue with the water supply or the inlet valve.
What causes Samsung 4E error?
Samsung 4E error is caused by a water supply issue. This can be due to a closed water valve, a blocked inlet filter, a kinked inlet hose, or a faulty inlet valve. Low water pressure from the mains supply can also cause this error.
Can I fix Samsung 4E error myself?
Yes, you can check the water supply valves, clean the inlet filter, and check the inlet hose for kinks. If the error persists after these checks, the inlet valve may be faulty and will need to be replaced by a qualified appliance technician.
