Sometimes even Samsung washing machines, famous for their technological advancements, may encounter error codes that demand immediate attention for optimal performance. Let’s try to understand the whole specifics of this kind of error.

When does it happen

HOT Error Code:

  1. Occur When: The HOT error code typically occurs when the washing machine detects an issue with excessive water temperature during the wash cycle.
  2. Possible Causes:
    • High water temperature: it may be caused by extremely high temperature of the hot water supplied to the washing machine or a malfunction in the hot water valve may result in continuous hot water flow.
    • Faulty temperature sensor: possible reasons for this are inability of the temperature sensor to accurately detect water temperature or poor electrical connections affecting sensor performance.
    • Control board issues: it may be caused by short circuits or other electrical issues affecting the control board’s performance.
    • Water Inlet Filter Obstruction: potential reason of this is buildup of debris or foreign particles in the water inlet filters.
  3. What parts of the washing machine are responsible for this error code?
Error Code Responsible Components
HOT Temperature sensor.
HOT Control board.
HOT Water inlet filter.

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

Inspect Temperature Sensor:

  • Examine 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 observe if the machine operates without triggering the HOT error.
  • This helps determine if the issue is specific to hot water-related components.

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 temperature sensor.

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 HOT error code.

Professional Assistance:

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


The HOT error code in Samsung washing machines signals potential issues with water temperature, the temperature sensor, or the control board: this guide was made for solving this. Regular maintenance practices and prompt attention to error codes contribute to the longevity and reliable performance of the washing machine.
