tE
Samsung Washing Machine
Severity: ModerateWhat Does This Error Mean?
The tE error means the temperature sensor in your washer is not working. The washer can't measure the water temperature correctly. Cycles that need hot or warm water will not work properly.
Affected Models
- WF45R6100AW
- WF50R8500AV
- WF42H5000AW
- Most Samsung front-load and top-load washers
Common Causes
- The temperature sensor (thermistor) has failed
- The wiring between the thermistor and the control board is loose or damaged
- The heating element has a short circuit
- The main control board is not reading the sensor correctly
- A power surge damaged the sensor or its circuit
How to Fix It
-
Unplug the washer from the wall and wait 2 minutes.
This performs a full reset of the control board and sensors.
-
Plug the washer back in and try running a cold water cycle.
Cold cycles don't rely on the temperature sensor as much. If it works, the sensor is likely the issue.
-
Check your home's hot water supply by running hot water at a nearby faucet.
Make sure hot water is actually reaching the washer's location.
-
Inspect the hot water inlet hose connection at the back of the washer.
Make sure the hot water hose is connected to the hot water valve and not crossed with cold.
-
If the error persists, the thermistor or heating element needs professional replacement.
The thermistor is a small sensor inside the tub — not a DIY repair for most people.
When to Call a Professional
If a reset doesn't fix the tE error, you'll likely need a technician. The thermistor is inexpensive but located inside the machine. Heating element issues also require professional diagnosis. Expect repair costs of $120–$280 including parts and labor.
Frequently Asked Questions
Can I still wash clothes with the tE error?
You may be able to run cold water cycles. But warm and hot cycles will not heat water correctly. It's best to get the sensor fixed to avoid washing at the wrong temperature.
What is a thermistor in a washing machine?
A thermistor is a small temperature sensor inside the wash tub. It tells the control board how hot or cold the water is. The board uses this info to heat water to the right temperature.
How much does a Samsung washer thermistor cost?
The part itself is quite cheap — usually $10–$30. Professional installation adds $100–$200 for labor. Total repair cost is typically $120–$280.
