What You Need to Know:

The HC error code indicates a problem with your washer’s heating system. This crucial component heats the water for your laundry cycles. The HC or HE code specifically means the water temperature isn’t rising as expected. This could be due to several reasons:

  • Thermistor malfunction: This sensor measures water temperature. If it can’t detect a 1°C/34°F increase within 3 minutes, the HC code triggers.
  • Heater or relay malfunction: The heater might be short-circuited, have a loose wire, or have a stuck relay.
  • Calcium buildup: Mineral deposits on the heater or thermistor can interfere with accurate temperature readings.
  • Water level sensor issue: If the pressure sensor malfunctions, the heater might activate without water, leading to a rapid temperature rise and the HC code.
Variations and their clues:
Related Error CodesThier Meaning
HC, HE, E5, HC1, HE1, E1, Ec:These codes generally point to heater assembly issues like short circuits or loose wires.
HC2, HE2:These codes indicate the drying sensor and drying safety thermostat, also known as the manual reset thermostat (located near the scroll duct heater), detect an overheating issue.
HC3, HE3:These codes are specific to washing machines with steam functions and signal a problem with the steam system.

Resolving the HC Error Code on Your Samsung Washing Machine: Troubleshooting and Fixes

Before you begin:

  • Safety first! Unplug your washer before performing any maintenance.

Troubleshooting Steps:

Basic Checks:
  1. Power Reset: Sometimes a simple power cycle can fix glitches. Unplug the washer for 15 minutes, then plug it back in and restart the cycle.
  2. Visual Inspection: Check for loose wires around the heater assembly, main board, and (in combo models) drying heater. Look for calcium buildup or damage on the heater and temperature sensor.
  3. Water Flow: Ensure both hot and cold water taps are fully open and delivering lukewarm water.
  4. Hose Check: Make sure water hoses are clear, not kinked, and properly connected.

Advanced Troubleshooting (Proceed with Caution!):

Warning: These steps require some technical knowledge. If you are unsure, consult your Samsung technician.

  1. Cleaning: Use a descaling solution (follow manufacturer instructions) to clean mineral buildup on the heater and thermistor.
  2. Troubleshooting HC2 and HE2 Errors (Specific to HC2 and HE2):
    • Safety Thermostat Reset: The HC2 and HE2 errors often trigger due to the safety thermostat detecting overheating. Locate the reset button on the thermostat (usually near the heater housing and fan outlet duct) and gently press it.
      • If the safety thermostat sensing seems unstable, replace the thermostat.
      • If the error persists, the thermostat might need replacement.
    • Heater Fan Motor and Blower Wheel Assembly: Check for any blockages in the fan motor or blower wheel assembly that could restrict airflow and cause overheating. Carefully remove any debris or buildup using a soft brush. Ensure the motor spins freely.
Measuring Resistance of Safety Thermostat to Diagnose Samsung Washer Error Codes HC and HE
Measure the resistance of the safety thermostat to diagnose the HC error code on your Samsung washing machine. This might help identify a faulty thermostat or confirm proper functionality. Use a multimeter and follow safety precautions. Consult the washer manual for specific instructions on locating the thermostat.
  1. Heater Check (using a multimeter): Set your multimeter to ohm mode and measure the heater’s resistance (around 16–28 ohms). Replace if outside this range.
Measuring Resistance of Thermistor & Heater to Diagnose Samsung Washer Error Codes HC and HE
Troubleshooting the HC error code on your Samsung washing machine: Checking Thermistor and Heater Resistance
  1. Thermistor Check (using a multimeter): Set your multimeter to ohm mode and measure the temperature sensor’s resistance (around 52–55 kiloohms at 25°C/77°F).
    • If the resistance is within the specified tolerance range, the thermistor is likely functional.
    • If the resistance deviates significantly, replace it.
  1. Main Board (last resort): If the error persists, replacing the main board might be necessary.


By following these troubleshooting steps, you can effectively address the HC error code on your Samsung washing machine. Remember to check for visible issues, ensure proper water pressure and temperature, clean the heater and thermistor, and test components as necessary.

FAQs about the Samsung Washing Machine HC Error Code:

Don’t worry, these codes all point to the same issue: a problem with your washer’s heater. The specific code might offer additional clues, but the HC error indicates the water isn’t heating properly, leading to a chilly wash cycle. This guide walks you through troubleshooting steps to get your warm water flowing again!

The HC error often arises from calcium buildup or clogged components. To prevent it:

  • Clean your washer regularly.
    • Follow your manual’s cleaning instructions, including descaling the heater and thermistor.
  • Use the correct detergent.
    • Avoid harsh detergents that can contribute to buildup.
  • Don’t overload the washer.
    • Excess laundry can strain the heating system.
  • Check the water pressure.
    • Ensure your water pressure is sufficient for optimal washing.

These codes signal that your appliance’s safety thermostat tripped due to overheating during the drying cycle. Follow these steps to address the issue:

A. Reset the safety thermostat:

  • Look for the reset button on the heater assembly (consult your user manual for its location).
  • Gently press and hold the button for a few seconds.
  • If the error persists, move to step B.

B. Check the heater fan and blower assembly:

  • Note: This involves some disassembly. Unplug your washer and consult your manual for specific instructions.
  • Carefully remove the heater assembly, following your manual’s steps.
  • Inspect the fan and blower wheel for any blockages like dust, lint, or debris.
  • If blocked, carefully clean them with a soft brush.
  • Reassemble the heater assembly, ensuring all connections are secure.
