HC2
Samsung Washing Machine
Severity: ModerateWhat Does This Error Mean?
The HC2 error means your Samsung washer detected water that is too hot during the wash cycle. This usually happens when the hot and cold water supply hoses are swapped, or there is a problem with the temperature sensor. The machine stops to protect your clothes from heat damage.
Affected Models
- WF45R6100AW
- WF50R8500AV
- WF45T6000AW
- WF42H5000AW
- Most Samsung front-load washers
Common Causes
- Hot and cold water inlet hoses are connected in reverse
- Hot water supply is unusually hot (above 122°F / 50°C)
- Faulty water temperature sensor (thermistor)
- Control board sending incorrect signals to the heater
- Steam function malfunction on steam-enabled models
How to Fix It
-
Turn off the washer and unplug it from the wall.
Always disconnect power before checking water connections. Safety first.
-
Check the water supply hoses at the back of the machine.
Hot water should connect to the H (hot) inlet. Cold water connects to the C (cold) inlet. They are often labeled or color-coded.
-
If the hoses are swapped, switch them to the correct inlets.
Turn off your home's water supply valves before disconnecting any hoses to avoid a flood.
-
Check your home's hot water heater temperature setting.
If your water heater is set above 120°F, lower it slightly. Very hot water can trigger this error even with correct hose connections.
-
Plug the washer back in and run a test cycle.
If the HC2 error reappears after fixing the hoses, the temperature sensor likely needs professional replacement.
When to Call a Professional
If your hoses are connected correctly and the error keeps coming back, the temperature sensor or control board may need replacement. A technician can diagnose this with a multimeter. Expect repair costs of $120–$250 depending on the faulty part.
Frequently Asked Questions
Why does my Samsung washer show HC2 but the hoses look fine?
Even if the hoses appear correct, the temperature sensor inside the machine may be faulty. It can give false readings that trigger the HC2 error. Try unplugging the washer for 5 minutes and restarting. If it keeps happening, a technician should test the thermistor.
Can I still use my washer with the HC2 error?
No — the washer stops the cycle to protect your clothes from overheating. You need to fix the root cause before it will complete a wash. Start by checking that your hot and cold hoses are connected correctly.
How do I know which hose is hot and which is cold?
Hot water hoses typically connect to the inlet marked H or HOT, often on the left side. Cold water connects to the C or COLD inlet, usually on the right. You can also feel the hoses briefly after turning on the water — the hot one will be warm.
