Step-by-Step DIY Fix Guide
- SAFETY: Disconnect power at the circuit breaker.
- Reset by restoring power after 60 seconds and running a short rinse cycle.
- If tE returns, call Samsung Support at 1-800-726-7864.
If the warning comes back after restart
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
- tE returns after a single 60-second power reset
What This Error Means
Error tE on your Samsung dishwasher means: The dishwasher's temperature sensor (thermistor) is returning readings that are outside the expected range for normal operation. The dishwasher cannot accurately control the water heating cycle and has stopped to prevent operating at an unknown temperature. The dishwasher's self-diagnostic system has flagged this condition and may have paused the current cycle.
The most frequent cause is thermistor failed — sensor resistance has drifted outside calibration range. Work through the causes and steps below before calling a technician.
Samsung's official guidance classifies tE as a technician-only fault. A 60-second power reset is the only DIY step. If the code returns, contact Samsung Support at 1-800-726-7864.
Temperature errors often clear with a power cycle and pre-running the kitchen faucet before starting the dishwasher. This ensures the supply line delivers water at the correct starting temperature rather than cold standing water from overnight. If the error persists after two attempts, a sensor or heating element fault is the cause.
Most Likely Cause by Symptom
The Samsung dishwasher may stop, pause, or refuse to complete the cycle normally.
Likely cause: Thermistor failed — sensor resistance has drifted outside calibration range
Check first: SAFETY: Disconnect power at the circuit breaker.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Wiring fault between the thermistor and the control board — loose or damaged connector
Check first: Reset by restoring power after 60 seconds and running a short rinse cycle.
Common Causes
- Thermistor failed — sensor resistance has drifted outside calibration range
- Wiring fault between the thermistor and the control board — loose or damaged connector
- Control board thermistor input circuit failed
- Thermistor coated with scale or mineral deposits causing thermal insulation and inaccurate readings
What Not to Do
- Do not run the dishwasher when tE is active — the heating element cannot be safely regulated without accurate temperature feedback
Model and Display Variation Notes
Model-family notes
- Samsung dishwasher display wording and code formats can vary by series.
- If your model behaves differently, check the owner manual before trying any deeper maintenance step.
Display and panel differences
- Panel wording can vary by series, so confirm the exact code pattern before buying parts.
Parts, Tools and Service Options
Service option
Samsung service visit if the warning returns after the basic checks are complete.
Manual and model check
Check your exact model and manual before ordering any Samsung dishwasher parts.
Common parts
- Thermistor/temperature sensor ($20–$50)
- Wiring harness section if wiring fault is confirmed ($20–$50)
- Control board if thermistor input circuit on board has failed ($80–$200)
This section stays service-first because the page points more strongly toward support or professional repair than a routine parts purchase.
When Not to Keep Troubleshooting
tE returns after a single 60-second power reset
How to Prevent It Recurring
- Run a dishwasher cleaner tablet cycle monthly — mineral scale buildup on the thermistor is a known cause of tE on older dishwashers in hard-water areas
Related Error Codes
HE
Samsung dishwasher error HE usually means the machine is not heating the wash water correctly.
HC
The dishwasher has detected that the water temperature is too high for the current cycle on rotary spray arm models. The heating element or water supply is delivering water above safe operating limits, and the cycle has been interrupted to prevent damage.
3E
The incoming water supply to the dishwasher exceeds the safe operating temperature limit (above 176°F / 80°C). Samsung dishwashers heat their own water and are designed for a cold or warm supply — not a supply that is already at high temperature.
