Samsung HC Error Code: High Temperature Problem
Updated: February 2026
The Samsung HC error code appears when your washing machine detects that water temperature has exceeded safe limits. This error protects both the washer components and your laundry from damage due to excessively hot water, which can shrink clothes, damage fabrics, and harm washer parts.
Causes of Overheating
Excessive water temperature typically results from a stuck heating element that won't turn off, a faulty thermistor providing incorrect temperature readings, control board problems that don't shut off heating properly, or incoming hot water that's hotter than expected from your home's water heater.
Immediate Action
- Stop the cycle immediately and unplug the washer
- Turn off the hot water supply valve behind the washer
- Allow the washer to cool for at least 30 minutes before opening
- Once cool, open the door and remove any laundry inside
- Check your home water heater temperature setting (should be 120°F maximum)
Testing Water Heater
An excessively hot home water heater can trigger HC errors. Check your water heater thermostat - it should be set to 120°F (49°C) maximum. If it's set higher, reduce the temperature and wait several hours for the water to cool before testing the washer again.
Thermistor Issues
If home water temperature is normal but HC persists, the washer's thermistor may be reading incorrectly, causing the control board to think water needs more heating when it's already hot. The thermistor could also be faulty and not signaling when temperature is too high.
Heating Element Problems
A heating element that's stuck on or a control board that won't shut off the heating circuit will cause dangerous overheating. The element should only activate when needed and shut off once target temperature is reached. If it stays on continuously, it must be replaced.
Diagnosing whether the thermistor, heating element, or control board is causing HC errors requires testing with specialized equipment. Professional service is essential for this error as it involves safety concerns related to high temperatures and electrical components that control heating systems.
