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.

Difficulty

Try the basic checks, but the usual fix is a technician's job.

Safety first: unplug the washer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung tC

  1. 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.

  2. 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.
