The Samsung washing machine TE2 error is a specific fault code that indicates a malfunction in the temperature sensing system of your appliance. While often grouped with general “tE” codes, the TE2 designation typically points to a more specific issue with the fan housing duct sensor (on washer-dryer combos) or the water temperature thermistor, depending on your specific model.
When this error appears, your washer will stop mid-cycle or fail to start, as the control board cannot verify that the water or drying air is at a safe and correct temperature. This guide provides a professional, step-by-step approach to diagnosing and fixing this issue using standard tools like a multimeter.

What Does the TE2 Error Code Mean?
In the world of Samsung appliances, “tE” stands for “Temperature Error.” The number following it (1, 2, or 3) often helps pinpoint the exact component failing.

- Standard Front Load Washer: The TE2 error usually relates to the NTC sensor (Negative Temperature Coefficient sensor) inside the heating element assembly. This sensor monitors water temperature.
- Washer-Dryer Combos: If your machine also dries clothes, TE2 is frequently caused by a faulty temperature sensor in the fan housing duct. This sensor monitors the air temperature during the drying cycle.
Regardless of the location, the control board has detected an open circuit, a short circuit, or resistance readings that are out of the expected range.
Samsung Washing Machine TE2 Error Troubleshooting Steps
To resolve the Samsung washing machine TE2 error, follow these diagnostic steps in order. Always prioritize safety by unplugging the machine before removing any panels.
1. Perform a Hard Reset (Error Code Reset)
Before opening the machine, attempt to clear a temporary glitch in the control board.
- Unplug the washing machine from the power outlet.
- Press and hold the Power button for 60 seconds to discharge any residual electricity.
- Wait at least 5 minutes before plugging it back in.
- Run a short “Rinse + Spin” cycle to see if the error returns.
2. Enter Diagnostic Mode
Entering diagnostic mode can help you confirm the error without running a full cycle. While the button combination varies by model, a common method for a front load washer is:
- Turn the washer on.
- Press and hold Delay Start (or Soil Level) and Temp buttons simultaneously for 3-5 seconds.
- Or: Press Spin + Soil Level + Power simultaneously.
- Once in test mode, the display may show saved error codes. Use the dial to toggle through tests. This mode allows you to check if the sensor is sending live data to the board.
3. Inspect the Wiring Harness
Vibration during high-spin cycles can cause connections to loosen or wires to chafe.
- Remove the top or back panel of the washer.
- Locate the thermistor connections. For the water heater, this is usually at the bottom of the tub near the heating element. For the duct sensor (combos), look near the fan housing at the top.
- Check the wiring harness for any signs of corrosion, breaks, or burn marks.
- Ensure the plastic connector is firmly seated. A loose plug is a very common cause of the TE2 error.
4. Test the Thermistor Resistance
If the wiring looks good, the temperature sensor itself is likely the culprit. You will need a multimeter to test its internal resistance.

How to Test:
- Disconnect the thermistor wire connector.
- Set your multimeter to the Ohms (Ω) or Resistance setting (20k or 200k scale).
- Place the probes on the two metal pins inside the sensor’s connector.
Expected Values:
- Water NTC Sensor: At room temperature (approx. 77°F / 25°C), the resistance should typically be between 10kΩ and 15kΩ or 35kΩ and 45kΩ, depending on the model generation. Consult your specific tech sheet (usually found taped inside the machine).
- Duct Sensor (Dryer Combo): These often read differently. If you read 0Ω (continuity), the sensor is shorted. If you read Infinity (OL), the sensor is open (broken). Both indicate a bad sensor.
If your meter reads “OL” (Open Loop) or “0.0” (Short), the sensor is defective and must be replaced.
5. Check the Heating Element
While less common for the TE2 code specifically, a compromised heating element can sometimes trigger temperature errors if it is leaking voltage to the ground.
- Switch your multimeter to continuity mode.
- Test between the heating element terminal and the metal casing of the element (ground).
- There should be no continuity (no beep). If there is continuity, the element is grounded and needs replacement.
6. Main Control Board Inspection
If the sensor, wiring, and heating element all test fine, the issue may lie with the control board (PCB).
- Trace the wires from the sensor back to the main PCB.
- Inspect the board for “blown” capacitors or burn marks near the sensor connector.
- If the board is not reading the sensor despite a good connection and a functioning part, the board likely requires replacement.
Summary of Repair
The Samsung washing machine TE2 error is rarely a fatal issue for the appliance. In 90% of cases, it is resolved by replacing the inexpensive thermistor or repairing a damaged wire in the harness.
| Component | Likely Fault | Solution |
|---|---|---|
| Thermistor (NTC) | Open or Short Circuit | Replace Sensor |
| Wiring Harness | Broken/Corroded Wire | Repair or Replace Wiring |
| Control Board | Logic Failure | Replace PCB |
By systematically checking the resistance with a multimeter and inspecting the physical condition of the wiring, you can accurately diagnose the problem and restore your washer to working order. Remember to always clear the error code by running a short test cycle after completing your repairs.
Frequently Asked Questions
What is the difference between a tE error and a TE2 error?
While both indicate a temperature-related malfunction, a standard “tE” code is a general warning, whereas “TE2” is more specific. On standard front-load washers, TE2 usually points to the water temperature NTC sensor. On washer-dryer combo units, it almost always refers to a fault with the fan housing duct sensor used during the drying cycle.
Can I continue to wash clothes while the TE2 error is active?
No. When the control board detects a TE2 error, it enters a safety mode and halts operation. This is because the machine cannot accurately determine if the water or air is reaching dangerous temperatures, which could lead to overheating or damage to your clothing.
How do I know if the thermistor needs to be replaced?
The most reliable way to confirm a faulty thermistor is by using a multimeter to check its resistance. If the meter displays “OL” (Open Loop) or “0.0” (Short Circuit), the internal components of the sensor have failed. You should also replace it if the resistance reading is significantly outside the manufacturer’s specified range (typically 10kΩ to 45kΩ at room temperature).
Will a hard reset permanently fix the TE2 error code?
A hard reset will only fix the issue if the error was caused by a temporary communication glitch in the control board. If the error returns shortly after the reset or during a specific part of the cycle, it indicates a physical hardware failure—such as a broken wire or a dead sensor—that must be repaired manually.
