Whirlpool Washer - F24 Error Code

Water temperature sensor error.

Meaning

Water temperature sensor error.

The F24 error indicates that the washer’s water temperature sensor (NTC thermistor) is reading values outside the expected range. Whirlpool Duet washers rely on this sensor to regulate water temperature during wash cycles. If the sensor is open, shorted, or providing erratic readings, the washer triggers F24 to prevent incorrect temperature control.

Symptoms

  • Washer stops early in the cycle
  • Water temperature seems incorrect
  • F24 appears shortly after filling
  • Washer refuses to start certain cycles

Causes

  • Faulty NTC temperature sensor
  • Loose or corroded wiring harness
  • Moisture intrusion in the sensor area
  • Control board misreading sensor values
🔧

Step-by-Step Fixes

  • Inspect the temperature sensor wiring.
  • Test the sensor with a multimeter (typically 10–12kΩ at room temperature).
  • Replace the sensor if readings are out of range.
  • Inspect the control board if the sensor tests good.
⚠️

Safety Notes

  • Disconnect power before accessing the heater or sensor.
