Technically Reviewed by Oleg Chudnovski on Oct 28, 2025 | Written by Oleg Chudnovski

Samsung washing machines, known for their cutting-edge technology, may occasionally display error codes that signal potential issues. Let's delve into the specifics of the E4 (E1) error code, exploring when it occurs, the components responsible, and practical steps to resolve the problem.

When does this code take place

E4 (E1) Error Code:

1. Occurs When: The E4 (E1) error code is typically related to water drainage problems during the washing cycle.
2. Possible Causes:
   • Clogged Drainage System (the E4 (E1) error code often occurs when there is a blockage or restriction in the drainage system). Causes for this event may be accumulation of lint, debris, or foreign objects in the drainage hose or blockage in the washing machine's drainage filter.
   • Pump Failure (the washing machine relies on a pump to evacuate water during the drainage cycle. Pump failure can trigger the E4 (E1) error code. Causes of this event may be stuck or damaged impeller within the pump or electrical or mechanical issues with the pump motor.
   • Improper Drainage System Installation (incorrect installation of the drainage system can lead to water evacuation problems, causing the E4 (E1) error). The causes of this situation could be incorrectly connected or kinked drainage hose or leaks or disconnections in the drainage system.
   • Sensor or Circuit Issues (malfunctions in the water level sensor or related circuits can also contribute to the E4 (E1) error code). Potential causes of this are sensor failure to accurately detect water levels or issues with the communication circuit between the sensor and the control board.

• 3. What parts of the washing machine are responsible for this error code?

Understanding the specific components tied to the error code is crucial for effective diagnosis and resolution.

Verify the Drainage System:

• Ensure the drainage hose is properly connected and not kinked.
• Check for any leaks or disconnections in the drainage system.

Run a Test Cycle:

• After clearing obstructions and ensuring proper drainage, run a test cycle to confirm issue resolution.
• Monitor the washing machine during the test cycle for any abnormal behavior.

Conclusion

The E4 (E1) error code in Samsung washing machines is typically associated with drainage issues, potentially caused by obstructions in the drainage system or pump failure, or may be caused by sensor troubles. By following the outlined troubleshooting steps, you can address these issues effectively and restore the optimal functionality of their washing machines. Regular maintenance, including periodic checks of the drainage system, contributes to the longevity and reliable performance of the appliance.
