Troubleshooting the HC error code on your Samsung washing machine

In this guide, we’ll explain the HC error code on a Samsung washing machine (which may also appear as HE, E5, HC1, HE1, E1, Ec, HC2, HE2, HC3, or HE3), what it means, its common causes, and how to fix it.

HC error code on your Samsung washing machine? Here’s How to Fix It

Understanding and Fixing the HC Error on Your Samsung Washer

The HC (Heater Check or Heater Error) code indicates that the washer has detected a problem with the water heating system. Depending on the model, the code may also appear as HE, HE1, Hr, HC1, or 1HC. 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 Codes	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.

3. 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.

4. 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.

Conclusion

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.
