A common Samsung washing machine problem is the 4E error code. This error signals a problem with the water supply. This can be due to blocked water hoses, closed water supply valves, or a malfunctioning water inlet valve.
This repair guide will work to fix the 4E error code on various Samsung washer models, such as WF42H5200AW, WF56H9100AG, and WF45K6500AV.
Quick Tip – Turn the Power Off
To fix an error code 4E in a Samsung washer, try turning off the power for a few minutes before turning it back on. This can usually reset the washer and clear the error.
Step 1. Inspect the Water Supply Hoses
A blocked or kinked water hose can prevent water from flowing into the washing machine, leading to the 4E error code. Inspect the hoses for any visible damage, kinks, or blockages that may be restricting water flow.
How to fix it:
Check the water supply hoses for any kinks or blockages. If damaged, replace them. If kinked, straighten them out and ensure they’re properly connected to the washing machine and water supply.
Step 2. Examine the Water Supply Valves
Ensure that the water supply valves connected to the washing machine are fully open. A closed or partially open valve can reduce or prevent water flow, resulting in the 4E error code.
How to check water supply:
Make sure the water supply valves connected to the washing machine are fully open. If they’re closed or partially open, turn them counterclockwise to open them completely.
Step 3. Clean the Water Inlet Valve
A clogged water inlet valve can also cause the 4E error code. Over time, debris and mineral deposits can accumulate in the valve, obstructing water flow. Regularly cleaning the valve can prevent this issue.
How to clean it:
Turn off the water supply and disconnect the hoses from the washing machine. Remove the water inlet valve and clean it thoroughly with a brush and a solution of water and vinegar. Reassemble and reconnect the hoses.
Step 4. Replace the Water Inlet Valve
A malfunctioning water inlet valve may not open correctly or at all, preventing water from entering the washing machine. If this is the case, the valve will need to be replaced.
How to fix the water inlet valve:
If cleaning the water inlet valve doesn’t resolve the issue, it might be faulty and need to be replaced. Purchase a replacement valve and follow the manufacturer’s instructions to install it.
Step 5. Check the Pressure Sensor
The pressure sensor monitors water levels in the washing machine and communicates with the control board. If the sensor is malfunctioning, it can cause the 4E error code. A faulty pressure sensor will need to be replaced.
How to check pressure switch:
If the problem persists, the pressure sensor might be malfunctioning. Consult your washing machine’s user manual to locate the sensor, and replace it if necessary.
More error code help: The 4E error code, also known as the “Water Supply Error,” occurs when the washing machine detects a problem with the water supply. This can be caused by a variety of issues, including low water pressure, blocked water inlet filters, or faulty components within the washer itself. When this error occurs, the washing machine will not fill with water and cannot proceed with the washing cycle.
How do I reset the 4E error code on my Samsung washing machine?
Unplug the washing machine from the power source, wait for a few minutes, and plug it back in. This should reset the error code. If the problem persists, follow the steps in this guide to troubleshoot and resolve the issue.
Can I use my Samsung washing machine with the 4E error code?
No, using your washing machine with the 4E error code can cause further damage to the appliance. It’s essential to identify and resolve the issue before using the washing machine again.
Regular maintenance and inspection of your washing machine can help prevent the 4E error code and ensure your appliance continues to run efficiently.
