Error code tE
Appliance Dishwasher
Quick answer

tE on Kenmore dishwashers numbered 722.146 reports a failed thermistor (temperature sensor).

Model compatibility

Kenmore reuses codes across series and model years, so tE may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Thermistor (temperature sensor) failure.

tE summary

  • Display: tE
  • Meaning: thermistor (temperature sensor) failure
  • Models: Kenmore dishwashers with model numbers beginning 722.146

Technician checks in the manual

  • Disconnect the dishwasher from power first.
  • Test resistance through the thermistor on the heater; the heater assembly, thermistor included, is replaced if the reading is out of range.
  • Test the thermistor wires that connect to the electronic control board. Correct readings there but a board that cannot sense the thermistor mean a new board.
  • Infinite or near-zero readings through the sensor wires mean a wiring failure to find and repair.
