Samsung Dishwasher tE error code

The temperature sensor (thermistor) is giving bad readings, so the dishwasher cannot verify the water temperature. The cycle stops because heating cannot be controlled safely.

Also shown as: tE, TE, tC

Last updated: October 6, 2026

Quick answer: Samsung dishwasher error code tE: temperature sensor error. The most common cause is failed thermistor. Try this first — run Samsung's empty-cycle test. If that does not clear it, power-cycle at the circuit breaker. If the code persists, call a qualified technician.

What causes the tE error?

  • Failed thermistor
  • Loose or damaged thermistor wiring
  • Corroded sensor connector
  • Scale buildup on the sensor
  • Failed main control board misreading the sensor

How to fix Samsung tE — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Run Samsung's empty-cycle test
    Empty the dishwasher, add detergent, and run a Normal cycle. If tE appears on the empty cycle, the sensor circuit is confirmed faulty.
  2. Power-cycle at the circuit breaker
    Switch the breaker off for 30 seconds and back on, then retry. This resets the temperature-sensing electronics after a transient glitch.
  3. Clean the filter and tub
    Heavy soil and scale around the sensor area can distort readings. Clean the filter and wipe down the tub interior before retesting.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • tE returns on the empty test cycle
  • The thermistor needs multimeter testing or replacement
  • Sensor wiring is damaged or corroded
  • The main control board is misreading the sensor

Frequently asked questions

What is the difference between tE and HE?

tE means the temperature sensor itself is giving bad readings. HE means the heater system is at fault. A bad sensor can cause heater-like symptoms, so technicians test the sensor first.

Will dishes still get clean with tE?

No - the dishwasher stops the cycle because it cannot control heating. Unheated washes leave dishes dirty and unsanitized.

Can I reset tE and keep using it?

A reset only helps if it was a one-time glitch. A returning tE means the sensor or wiring is faulty and needs replacement.
