Quick answer
A Samsung dishwasher tE error code means the control is reading a temperature sensor value out of range, most often from a failed thermistor, a loose sensor harness, or a heating element that has shorted. Unplug the dishwasher for 5 minutes first. If tE returns, test the thermistor for roughly 10 to 12 kilohms at room temperature and the heater for continuity. A replacement thermistor costs $20 to $50.
Samsung dishwasher code tE concerns temperature sensing or excess heat on the setup covered here. The thermistor, heater, wiring, and control can affect that system in different ways, so their tests should be interpreted separately. This guide moves from a power reset to sensor and heater checks, helping identify the fault before a replacement is selected.

What Does the Samsung Dishwasher tE Error Code Mean?
The Samsung dishwasher tE error code concerns temperature sensing or excess heat on the covered setup; the sensor, heater, wiring, and control can be involved.
Keep these points in mind.
- The control reads a temperature sensor value out of range or an interior that got too hot
- Which Samsung DW80 and DW50 families show it
A symptom points toward a system, but several parts in that system may cause it; the useful question is which observation separates those parts. Visible damage gives stronger evidence than a guess from age alone. An electrical fault needs a reading made at the right points.
What Causes a Samsung Dishwasher to Show tE?
The thermistor reports water temperature through a changing resistance; the heater provides heat under control of the board. An open sensor and a heater that stays on can both disturb the temperature system, but their electrical tests are different. A stuck button code belongs to a separate path.
The following details help narrow the decision.
| Condition or Detail | Meaning or Next Consideration |
| failed thermistor | Judge the sensor signal under the correct temperature and test conditions. |
| loose or corroded sensor harness | An interrupted connection can prevent a sound part from working. |
| heating element shorted or stuck on | Separate heat production from the temperature signal and wiring. |
| control panel glitch | Consider this after the related parts and wiring have been ruled out. |
| main PCB | Use this observation to narrow the fault before choosing a replacement. |

What would make this part a poor choice? A sound test result means you need to consider the other causes before ordering it.
How Do I Reset the tE Code on a Samsung Dishwasher?
Follow these steps to check this part of the fault.
Check the Reset and Response
- Power off.
- Disconnect power or breaker off 5 minutes.
- Restore power.
- Run a short cycle.
- The code returning means a hardware fault.
A reset can clear a temporary control state; it cannot remove a physical blockage or repair a broken wire. What happens after the reset matters more than a for a moment normal display. A returning fault suggests that the control is detecting the same condition again.
How to Fix the tE Code on a Samsung Dishwasher Step by Step
Follow these steps to complete the covered procedure for Samsung dishwasher tE error code.
Phase 1: Reset the Dishwasher
- Disconnect power for five minutes.
- Restore power and run a short cycle.
- Check whether tE returns.
Phase 2: Inspect and Test the Temperature Sensor
- Disconnect power.
- Locate the sensor at the heater base on the applicable model.
- Inspect it for damage.
- Test its resistance against the model range.
- Inspect its wires.
- Replace a sensor that fails the test.
Phase 3: Inspect and Test the Heating Element
- Inspect the heater for damage.
- Disconnect its terminals with power off.
- Measure resistance across the heater.
- Treat OL as an open heater.
- Inspect heater wires.
- Brush away residue.
Phase 4: Verify Wiring and Connections and Retest
- Disconnect power before opening the control area.
- Inspect wires for damage and loose plugs.
- Secure loose connections and replace damaged wires.
- Refit panels.
- Restore power and check the code.
How Do I Test the Thermistor on a Samsung Dishwasher With a Multimeter?
Use the stated test condition as well as the reading; a normal value at the wrong temperature or terminals can lead to the wrong conclusion.
Keep these points in mind.
- Unplug the sensor
- Expect roughly 10 to 12 kilohms at room temperature and a falling reading when warmed by hand
- OL means open
- Near zero means shorted
- Heating element should read roughly 10 to 30 ohms
- Not OL
Resistance is measured in ohms with the part disconnected from power; a kilohm is 1,000 ohms. Continuity means there is an electrical path through the tested part. OL usually means that path is open or beyond the meter range.
What Does the bE Error Code Mean on a Samsung Dishwasher?
These signs need to be read together; a single symptom can point to more than one cause, so the condition of the related parts matters too.
Keep these points in mind.
- A button on the control panel is stuck or shorted
- Clean the panel
- Power cycle
- Replace the panel if it persists
- How bE differs from tE
A symptom points toward a system, but several parts in that system may cause it; the useful question is which observation separates those parts. Visible damage gives stronger evidence than a guess from age alone. An electrical fault needs a reading made at the right points.
Should You Replace the Thermistor, the Heater, or Call a Technician?
Choose the repair that matches the confirmed fault; a cheaper part will not help if it belongs to a different part of the system.
Keep these points in mind.
- Reset free
- Thermistor $20 to $50 and 45 minutes
- Heating element $40 to $90
- Main PCB $120 to $250 last
- Call a technician when both parts test good
- The tub shows heat damage
- Or the unit is under warranty
A low-cost part is a good choice only when it corrects the confirmed fault; cleaning can solve a blockage, but it cannot repair a cracked housing or an open winding. A control board should come later in the diagnosis because a bad connection can create the same symptom. Parts cost is only part of the decision.
FAQ
Can the Dishwasher Run With tE Showing?
Normal temperature control is uncertain with tE active. A repeated fault or heat damage needs diagnosis before continued use.
Why Does tE Appear Only During the Dry Phase?
The fault may become visible only when the system heats or dries. The timing does not by itself prove the sensor is bad.
Does Hot Inlet Water Cause tE?
Water that is hotter than the model allows can affect temperature control. A returning tE also calls for sensor, heater, and wiring checks.
Clearing tE With One Resistance Reading
You have a clearer path when the symptoms, model, and test results agree; focus on the failed part and keep the nearby wiring, mounts, and seals in view. A sound diagnosis helps the repair solve the original problem.
Check the full model number, then choose the compatible thermistor or heating element so the tE code stays gone.
