Samsung Washer tC Error Code
Water temperature sensor error. Here is what it means and how to clear it, easiest fix first.
The washer's temperature sensor is giving a reading that is out of the expected range, or no reading at all. This usually means a failed temperature sensor (thermistor) or a loose wire to it, though very hot or very cold incoming water can occasionally trigger it.
Also shown as tE or tE1 depending on the model.
How to fix Samsung tC
Reset the power
Turn the washer off, then unplug it or switch off its circuit breaker for about 2 to 3 minutes. Restore power and start a new cycle. A one-time glitch often clears this way, so note whether the code comes back.
Confirm hose connections
Make sure the hot and cold hoses go to the correct inlets and both faucets are fully open, since reversed or restricted supply can cause unusual temperature readings.
When to call a technician
If the code returns after a reset, the temperature sensor or its wiring needs testing and likely replacement by a technician.
Parts that commonly cause tC
- Temperature sensor (thermistor)
- Wire harness
Order parts by your exact model number so they fit.

Can I fix Samsung tC myself?
Only the basic checks. You can safely try the steps above, but tC usually points to a part or fault that needs a technician.
What if tC keeps coming back?
