Whirlpool Washer F24 Error Code: Water Temperature Sensor Fault

Quick Answer

Whirlpool F24 is a legacy error code from older Duet front-load models that predates the F/E dual-code system. F24 means the water temperature sensor (NTC thermistor) is reading outside its expected range. On these older Duets, the thermistor is mounted on the outer tub near the heating element.

Whirlpool F24 is a legacy error code from older Duet front-load models that predates the F/E dual-code system. F24 means the water temperature sensor (NTC thermistor) is reading outside its expected range. On these older Duets, the thermistor is mounted on the outer tub near the heating element. The sensor is a 2-wire device that should read approximately 10,000 ohms at room temperature (77F). If it reads open circuit (infinity), the sensor wire is broken. If it reads near zero, the sensor is shorted. The most common cause on vintage Duets is corrosion at the sensor connector from years of exposure to humidity inside the washer cabinet. Clean the connector pins with contact cleaner before replacing the sensor.

What Does the F24 Code Mean?

F24 = temperature sensor fault on pre-2010 Duet models. Same as F3 E1/E2 on newer models. Sensor should read 10K ohms at room temp. Check connector corrosion first.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

NTC thermistor open or shorted40%
Connector pins corroded from age24%
Sensor wire insulation degraded14%
Heating element proximity causing sensor aging12%
Moisture damage to sensor10%

Symptoms You May Notice

  • F24 on display
  • Water temperature incorrect
  • Washer may skip heating phase
  • Error appears during fill
  • Washer runs cold on all settings

Can you reset a Whirlpool washer to clear the F24 code?

Unplug 60 seconds. F24 clears when sensor reads within normal range.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Unplug

Unplug. Access the sensor through the rear panel. Disconnect the 2-wire connector. Before testing the sensor, inspect the connector pins for green or white corrosion. Clean with contact cleaner and a small brush or pencil eraser.

2

Measure sensor resistance with multimeter set to 20K ohm range

3

Install new sensor, route wire carefully, reconnect

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

My washer shows F24 but newer guides show F3 E1. Are they the same?
Yes. F24 is the legacy code format used on pre-2010 Whirlpool Duet models. F3 E1 (open) and F3 E2 (short) are the equivalent codes on newer models. The sensor, testing procedure, and replacement part are identical.
How old is my Duet if it shows F24 instead of F3 E1?
F24-format codes were used on Duet models manufactured approximately 2005-2010. After 2010, Whirlpool transitioned to the F/E dual-code system. If your Duet shows F24, it is at least 15 years old.
Is it worth replacing a sensor on a 15-year-old Duet?
A $10-20 sensor is worth replacing regardless of age if the rest of the washer is working. The bigger question is whether other components are likely to fail soon. If this is the first repair, go ahead. If you have had multiple repairs recently, the washer may be approaching end of life.
