Quick answer: On a Samsung Washer, the tE error code (also shown as tC, tE1, tE2, or tE3 on different models) means the machine has detected a thermistor (temperature sensor) fault. Samsung Washer tE indicates that the water temperature sensor is providing a reading that is outside the expected range — either too high, too low, or a circuit error. In most cases, Samsung Washer tE is caused by a faulty thermistor or a loose wiring connection to the sensor, both of which can be tested and replaced without full machine disassembly.
The Samsung Washer tE error code specifically identifies a temperature sensing fault, separate from a heating element failure. The thermistor is a variable-resistance component whose electrical resistance changes predictably as water temperature rises. The Samsung Washer control board reads this resistance continuously and calculates the actual water temperature from it.
When the Samsung Washer shows tE, the control board has received a resistance reading that is too high, too low, or impossible for the operating conditions. For example, a sensor reading of -40°C or 200°C is clearly outside the drum temperature range during normal washing and indicates a sensor fault rather than actual temperature.
The thermistor itself can fail by developing an open circuit (infinite resistance) or a short circuit (zero resistance), both of which send readings to the Samsung Washer control board that are immediately recognized as invalid. A failed thermistor must be replaced to clear tE.
The wiring connector to the thermistor can come loose from machine vibration. An intermittent open connection produces the same signal as a failed sensor — the control board sees no reading — and the Samsung Washer displays tE. Reseating the connector may resolve the error without replacing the sensor.
If the wiring between the thermistor and the control board is pinched, burned, or corroded, the resistance reading reaching the board is corrupted. Samsung Washer tE can result from wiring damage that is not visually obvious without careful inspection.
If water from a leak inside the Samsung Washer reaches the thermistor connector or the sensor element itself, corrosion can develop and cause an open or short circuit. Inspect for water damage if the Samsung Washer has previously shown LE (leak) errors.
If the control board’s thermistor input circuit is damaged, it may interpret a normal sensor signal as a fault and display tE. This is uncommon and should only be considered after the sensor and wiring have been confirmed to be in good condition.
Follow the steps below one at a time — many error codes can be fixed faster than they look.
Unplug the Samsung Washer for 5 minutes and restart. A one-time tE error that does not repeat after reset is usually a transient fault and does not require further action.
With the Samsung Washer unplugged, remove the back panel. Locate the thermistor — it is a small component typically mounted into the heating element body or the lower tub wall. Inspect the wiring connector for looseness, bent pins, or corrosion. Disconnect and firmly reseat the connector.
Disconnect the thermistor connector and measure resistance across the thermistor terminals with a multimeter set to ohms. At room temperature (approximately 20–25°C), most Samsung Washer thermistors read between 10,000–15,000 ohms. Check your model’s service data for the exact specification. Open circuit or short circuit readings confirm sensor failure.
If the thermistor measures out of specification, replace it. Samsung Washer thermistors are small, inexpensive components that are often integrated with the heating element assembly or sold separately. Use the model number from your Samsung Washer door frame or back panel to find the correct part number.
If the thermistor resistance is normal, trace the full wiring path from the sensor to the control board. Look for wire insulation that is melted, chafed through, or pinched by a panel. Repair or replace damaged wiring sections as needed.
If the thermistor and wiring are both confirmed good but Samsung Washer tE continues, have the control board evaluated by an appliance technician. Board-level diagnosis requires specialized test equipment.
They are related but distinct. Samsung Washer HE indicates a heating element or overall heating circuit fault. Samsung Washer tE specifically points to the thermistor (temperature sensor). Both errors should be diagnosed carefully since the components are located in the same area.
Yes. Samsung Washer tE is a sensor signal fault, not necessarily a temperature fault. The water can be at a normal temperature while the sensor is sending an incorrect reading. The Samsung Washer cannot confirm temperature without a working sensor, so it stops the cycle.
Samsung Washer tE is a thermistor fault that prevents the machine from confirming water temperature during heated cycles. Start with a power reset, then check and reseat the thermistor connector. Test the thermistor resistance and replace it if out of specification. Most Samsung Washer tE errors are resolved by replacing the thermistor or repairing a loose wiring connection near the heating element.
