Understanding the Samsung Dishwasher “tE” Error
What it means: On many Samsung dishwashers the tE error code indicates a temperature-related fault — typically a problem with the temperature sensor (NTC thermistor) or the related heating circuit. The control board uses the sensor to monitor water and cycle temperatures; if the sensor reports an impossible value, is open/shorted, or communication is lost, the dishwasher will display tE and may halt the cycle or run improperly.
Why it occurs: Common causes include a failed thermistor, damaged wiring or connectors, a faulty heating element that affects temperature reading, or a defective main control board. Environmental factors (excessive moisture, corrosion, or physical impact) and occasional software/controller glitches can also trigger the code.
User impact: A tE error can lead to poor cleaning performance, longer or stalled cycles, incomplete drying, persistent error displays, or the dishwasher refusing to heat water. In some scenarios a malfunctioning temperature circuit could allow overheating (rare) or prevent sanitizing cycles from reaching necessary temperatures, which is a hygiene concern. Repeated attempts to run the dishwasher with a temperature fault can stress the heating element and electronics.
Common Causes
- Defective NTC temperature sensor (thermistor)
- Open or shorted wiring harness to the temperature sensor
- Loose, corroded, or water-damaged sensor connector
- Faulty heating element affecting temperature readings
- Malfunctioning main control board (PCB) or temperature input circuit
- Software or firmware glitch in rare cases
- Physical damage or moisture intrusion in the control compartment
Troubleshooting Steps
- Reset the dishwasher: Turn off power at the circuit breaker or unplug for 2–5 minutes, then restore power to see if the error clears.
- Run diagnostics (if available): Some Samsung models include service test modes; consult your manual to enter diagnostics and read temperature sensor codes.
- Inspect visible wiring and connectors: Pull out the unit (if comfortable) and check the harness running to the heater/sensor for loose plugs, corrosion, or broken wires.
- Check the sensor resistance: With the unit powered off and unplugged, locate the NTC thermistor and measure resistance with a multimeter. Typical resistances vary by model and temperature (consult service data), but an open circuit or extreme reading indicates a bad sensor.
- Test the heating element: Measure continuity of the heater; a shorted or open element can affect temperature readings and may cause the control to show tE.
- Swap or reseat connectors: Disconnect and reconnect sensor connectors to clear corrosion. Clean contacts carefully with a contact cleaner if needed.
- Inspect the control board: Look for burnt components, swollen capacitors, or water damage near the PCB. If the temperature input circuit is suspect, the board may need replacement.
- Replace the failed component: If diagnostics indicate the sensor or heater is faulty, replace that part and retest the dishwasher.
- After repair, run a short cycle: Confirm the tE code no longer appears and that the dishwasher reaches expected temperatures and completes cycles.
- Call a professional if uncertain: If you cannot safely access parts, if the PCB appears damaged, or if the error persists after replacing obvious parts, contact an authorized Samsung technician.
Maintenance / Prevention Tips
- Run the dishwasher on a regular cycle to discourage moisture buildup in the control area.
- Avoid over-sudsing by using recommended detergents and amounts — excess foam can penetrate gaskets and electronics.
- Keep the dishwasher door seals clean and dry to reduce moisture intrusion into the console and electronics.
- Inspect the wiring harness during annual maintenance for chafing, pinches, or rodent damage.
- Check and clean sensor connectors if you notice corrosion or discoloration.
- Use soft water or a water softener if your area has very hard water — mineral buildup can affect sensors and the heater.
- Replace worn or brittle cables and connectors rather than patching them temporarily.
- Avoid using high-pressure water jets near the control panel when cleaning the exterior.
- Ensure the dishwasher is level — excessive vibration can loosen connectors over time.
- Keep the dishwasher’s interior and spray arms free from large debris that could mask heating problems.
- Periodically run a sanitize or high-temp cycle (if available) to verify the heater reaches operating temperature.
- When you notice intermittent errors, document when they occur to help technicians diagnose environmental causes.
Frequently Asked Questions (FAQs)
Q: Is tE dangerous?
A: The tE code itself signals a sensor or temperature-circuit issue and is not typically an immediate safety hazard. However, because temperature control affects sanitization and drying, prolonged operation with a tE error can reduce cleaning effectiveness and, in rare cases, stress other components. If you smell burning or see smoke, cut power immediately and call a technician.
Q: Can I keep using the dishwasher with the tE error?
A: It’s not recommended to repeatedly run cycles while the error is present. You may experience poor cleaning, longer cycles, or no heating. Also, running with a known fault can cause further damage to the heater or electronics.
Q: How much does it cost to fix a tE error?
A: Costs vary: replacing a temperature sensor typically is a lower-cost repair (parts + labor), while a heating element or control board replacement is more expensive. Labor rates and part availability differ by region and model.
Q: Can a software update fix tE?
A: Occasionally, control glitches can be resolved by a firmware update or a power-cycle reset. If the error is hardware-related (sensor, wiring, heater, PCB), software updates won’t fix the root cause.
Q: How do I identify the temperature sensor location?
A: On many Samsung dishwashers the temperature sensor (NTC) is mounted near the tub or attached to the heater assembly. Consult your model’s service manual for exact location and resistance specifications.
Conclusion / Safety Notice
Temperature-related errors like tE should be addressed promptly to restore cleaning performance and avoid further damage. Always disconnect power before inspecting internal components and use proper tools. If you are not comfortable working with electrical components, or if diagnostics point to a damaged PCB or heating element, stop and contact a certified appliance repair technician. Faulty electrical repairs can create fire or electric shock risks.
If you have relevant model and serial numbers, provide them to the technician — that helps ensure quick, accurate part replacement. When in doubt, call a professional to ensure safe and lasting repair.
