What Does Error Code TE Mean on a Samsung Washing Machine?
Check and reseat the thermistor's electrical connector at both the sensor end and the control board — a loose or corroded connection is the most common trigger for TE, and reconnecting it firmly often clears the error immediately (takes about 10 minutes).
Fault description
When your Samsung washing machine displays the TE error code, it has detected a problem with the temperature sensor, also known as the thermistor. This small component is responsible for monitoring water temperature throughout the wash cycle and feeding that information back to the control board so the machine can heat water accurately.
When the thermistor sends a reading that falls outside the expected range — or sends no signal at all — the machine interprets this as a fault and halts the programme to prevent overheating or ineffective washing. You may notice the cycle stopping mid-wash, the display freezing on TE, or the machine refusing to start a new programme altogether.
The good news is that TE faults are often caused by a loose electrical connection rather than a failed component, which means a straightforward check can resolve the issue without any replacement parts.
Causes
- Loose or corroded thermistor connector — The wiring connector linking the thermistor to the control board can work loose over time due to vibration during spin cycles. Corrosion on the connector pins can also interrupt the signal, causing the control board to register a fault even if the sensor itself is fine.
- Faulty or failed thermistor — The thermistor itself can fail due to age, heat exposure, or manufacturing defect. When the sensor's internal resistance drifts outside its normal operating range, the control board can no longer trust its readings and triggers the TE error.
- Broken or damaged wiring harness — The wires running between the thermistor and the control board can become pinched, chafed, or broken — particularly where they pass through the drum housing or cabinet panels. A break anywhere in this circuit will produce the same TE fault as a failed sensor.
- Water or moisture ingress at the sensor — If water has reached the thermistor connector or the sensor housing, it can cause a short circuit or intermittent signal loss. This is more likely in machines that have experienced a leak or have been used in a very humid environment.
- Defective main control board — In a small number of cases, the control board itself is unable to correctly interpret the thermistor signal, even when the sensor and wiring are in good condition. This is the least common cause and is usually only confirmed after all other components have been tested and found to be working.
Step-by-Step Fix
- 1
Power cycle the machine
Switch the washing machine off at the mains socket and leave it unplugged for at least five minutes. This allows the control board to fully reset. Plug it back in, select a programme, and check whether the TE error returns before proceeding further.
- 2
Locate the thermistor
The thermistor on most Samsung washing machines is mounted on or near the heater assembly at the bottom of the drum housing. You will need to remove the rear panel of the machine to access it — unscrew the panel fixings and set the panel aside safely. Always ensure the machine is unplugged before opening the cabinet.
- 3
Inspect and reseat the electrical connector
Trace the wiring from the thermistor back towards the control board and check the connector at each end. Press each connector firmly until you feel or hear it click into place. Look for any signs of corrosion, burning, or bent pins. If the connector pins look corroded, gently clean them with a dry cotton swab or fine-grit sandpaper before reconnecting.
- 4
Inspect the wiring harness for damage
Run your fingers along the full length of the wiring between the thermistor and the control board, feeling for any pinched, frayed, or broken sections. Pay particular attention to areas where the wire passes through a panel edge or is held by a cable clip. Any damaged section of wire will need to be repaired or the harness replaced.
- 5
Test the thermistor with a multimeter
Disconnect the thermistor connector and set your multimeter to measure resistance (Ohms). Place the probes on the two thermistor terminals. At room temperature (around 20°C), a healthy Samsung thermistor typically reads between 4,000 and 6,000 Ohms. A reading of zero, infinity, or wildly outside this range indicates the sensor has failed and needs replacing.

Replace the thermistor if it has failed
If your multimeter test confirms the thermistor is faulty, fit a compatible replacement part for your specific model number. Disconnect the old sensor, noting how it is mounted and which way the connector faces, then fit the new one in the same orientation. Reconnect the wiring, refit the rear panel, and run a short test cycle to confirm the error has cleared.
- 7
Clear the error code and run a test cycle
After completing any repair, power the machine on and run a 40°C cotton cycle to confirm the machine heats water correctly and the TE code does not reappear. If the error returns despite a new thermistor and sound wiring, the fault is likely within the control board itself.

When to call a service technician
If you have replaced the thermistor, confirmed the wiring harness is intact, and reseated all connectors — but the TE error code continues to appear — the fault is most likely within the main control board. Diagnosing and replacing a control board requires specialist equipment and a good understanding of circuit board testing, and an incorrect diagnosis at this stage can be costly.
You should also contact a service technician if you find burnt or melted wiring, signs of water damage inside the machine's electrical housing, or if the machine is still under warranty and you do not want to risk voiding it by opening the cabinet yourself.

Frequently Asked Questions
Can I still use my Samsung washing machine while it shows the TE error?
It is not advisable to continue using the machine with a TE fault active. Without a working temperature sensor, the control board cannot regulate water heating safely, which could result in water that is too hot or a cycle that does not clean effectively. Resolve the fault before running further programmes.
How do I know if my Samsung thermistor is the right resistance?
At room temperature (approximately 20°C), most Samsung washing machine thermistors should read between 4,000 and 6,000 Ohms on a multimeter set to resistance mode. This value decreases as temperature rises. If your reading is zero, open circuit (OL), or far outside this range at room temperature, the thermistor should be replaced.
Will a power reset fix the TE error code on a Samsung washing machine?
A power reset can clear a TE error if it was triggered by a temporary signal glitch rather than a genuine component fault. Unplug the machine for five minutes, then restart it. If the error returns within the same or the next cycle, a physical inspection of the thermistor and its wiring is needed.
How long does it take to replace a thermistor on a Samsung washing machine?
For someone comfortable with basic appliance repair, replacing a thermistor typically takes between 30 and 60 minutes. The majority of that time is spent removing the rear panel and accessing the sensor. The sensor itself usually clips or screws into place and takes only a few minutes to swap out once you have access.
Is the TE error the same as the tE or tE1 error on Samsung machines?
Yes — on different Samsung washing machine models and display types, the temperature sensor fault may appear as TE, tE, tE1, or tE2. All of these relate to the thermistor circuit. The tE2 variant can sometimes indicate a specific issue with a secondary sensor used in certain drum-heating models, so always cross-reference with your model's manual if you see a numbered variant.
