Washing Machine 20

The “4E” error code on a washing machine is a common issue that many users encounter, particularly those using Samsung models. This code is typically associated with a problem in the water supply. This comprehensive guide aims to help you understand what the “4E” error code means, its causes, how to troubleshoot it, and how to prevent it from happening again.


The “4E” error code on a washing machine, particularly Samsung models, signifies a problem with the water supply. This could be due to low water pressure, a blocked or kinked water supply hose, a clogged water inlet filter, or issues with the pressure switch or water level sensor. To fix this, you can check the water supply, inspect and clean the water supply hose and inlet filter, reset the machine, or consult a professional technician if the problem persists.

What is the “4E” Error Code?

The “4E” error code is a signal that your washing machine is having trouble with its water supply. The machine’s sensors detect inadequate water supply and trigger this error code to alert you to the problem. This issue is commonly associated with Samsung washing machines and can occur in various models.

Causes of the “4E” Error Code

There are several potential causes for the “4E” error code:

  1. Low water pressure or flow rate: If the water pressure in your home does not meet the requirements of the washer (between 0.5bar and 8bar), this error code may appear.
  2. Blocked or kinked water supply hose: If the water supply hose is kinked or blocked, it can prevent water from flowing into the machine at the required rate, triggering the “4E” error.
  3. Clogged water inlet filter: Over time, the water inlet filter can become clogged with debris, preventing adequate water flow into the machine.
  4. Issues with the pressure switch or water level sensor: If the pressure switch hose is moved, clogged, or mechanically damaged, it can cause the 4E error code. In some cases, a malfunctioning water level sensor can also trigger this error.

Troubleshooting the “4E” Error Code

If your washing machine displays the “4E” error code, here are some steps you can take to troubleshoot the issue:

  1. Check the water supply: Ensure the water faucets are turned on completely to allow maximum water flow.
  2. Inspect the water supply hose: Straighten out any kinks or bends and remove any blockages.
  3. Clean the water inlet filter: Regular cleaning of the filter can prevent build-up that blocks water flow.
  4. Reset the machine: Unplug your washer for 30 seconds, then plug it back in. This can sometimes resolve the error code.
  5. Check the water hose mesh filter: Clean this filter at least twice a year to prevent build-up.
  6. Check the pressure switch hose and water level sensor: If the error code persists, you may need to check these components for any issues.

If you’re unable to resolve the problem yourself, consider contacting a professional technician for assistance.

Preventing the “4E” Error Code

To prevent the “4E” error code from appearing on your washing machine, regular maintenance is key. Regularly check and clean the water supply hose, water inlet filter, and dispenser drawer. Also, ensure that the water pressure in your home is within the required range.

Understanding the “4E” error code is essential for the better maintenance and longevity of your washing machine. By addressing these issues, you can ensure that your washing machine operates efficiently and prevent potential damage caused by inadequate water supply.

Remember, if the error persists after trying these steps, it’s always best to consult a professional technician for further evaluation and troubleshooting.

Your washing machine is an essential part of your home, and understanding its error codes can help you maintain its optimal performance and extend its lifespan.
