Navigating Samsung Washer HE/H1: Reasons and Solutions

Technically Reviewed by Oleg Chudnovski on Jan 21, 2026 | Written by Spark Service PRO Editorial Contributors

Samsung washing machines, renowned for their innovative features, may occasionally display error codes that require prompt attention for optimal performance. Let's start by exploring the intricacies of the HE/H1 error codes to understand when they occur, identify the responsible components, and provide practical solutions to address these issues.

When These Error Codes Occur

HE/H1 Error Codes:

1. Occur When: The HE/H1 error codes typically manifest when there is a problem with the washing machine's heating elements or temperature sensors during the operational cycles.
2. Possible Causes:
   • Malfunctions in the heating element (the HE/H1 error code may occur due to issues with the heating element responsible for warming the water during specific washing cycles). It may be caused by the gradual deterioration of the heating element over time, exposure to moisture that leads to its corrosion, or faults in the electrical components of the heating element.
   • Temperature sensor issues (the temperature sensor monitors the water temperature inside the washing machine). Possible reasons for this include the inability of the temperature sensor to accurately detect water temperature or poor electrical connections affecting sensor performance.
   • Overheating concerns (the washing machine may detect overheating, leading to these codes). It may be caused by overheating due to a malfunction in the heating element or the control board, or by issues with the control board regulating temperature.
3. What parts of the Samsung washing machine are responsible for this error code?

Understanding the specific components tied to the error codes is crucial for effective diagnosis and solution.

How to Solve the Issue

HE/H1 Error Codes:

Pause and Unplug:

• If the HE/H1 error occurs during a cycle, pause the machine and unplug it from the electrical outlet to ensure safety.

Check Heating Element:

• Physically inspect the heating element for visible signs of damage, such as corrosion or breakage.
• Confirm that the heating element is functioning properly.

Inspect Temperature Sensor:

• Inspect the temperature sensor for visible damage or loose connections.
• Measure the sensor's resistance using a multimeter to ensure it is within the specified range.

Run a Cold Water Cycle:

• Initiate a cold-water cycle to see if the machine operates without triggering the HE/H1 error.
• This helps determine whether the issue is specific to hot-water-related components.

Check Wiring Connections:

• Examine the wiring connected to the heating element and temperature sensor for any visible issues.
• Ensure all connections are secure and free from corrosion or damage.

Adjust Water Temperature Setting:

• Ensure that the washing machine's water temperature setting is appropriate for the selected cycle.
• Adjust the temperature setting if necessary.

Clean the Water Inlet Filters:

• Clean the water inlet filters to remove any debris that might hinder water flow to the heating element.

Run a Test Cycle:

• After performing the checks and potential fixes, run a test cycle to observe the machine's performance.
• Monitor for any recurrence of the HE/H1 error code.

Professional Assistance:

• If the error persists or if there are concerns regarding the heating element, temperature sensor, or control board, seek professional assistance.
• Technicians can conduct a thorough diagnosis and address more complex issues.

Final Summary and Key Takeaways for the HE/H1 Error Code

The HE and H1 error codes on Samsung washing machines usually indicate problems with the heating element, temperature sensor, or control board. These components play a crucial role in maintaining proper water temperature during each wash cycle, and any malfunction can lead to poor cleaning performance or interrupted cycles.

This guide walks you through the most common causes of these errors, how to recognize the symptoms, and the practical steps you can take to diagnose and fix the issue safely.
