Whirlpool Washer Error Code F/24

F/24 indicates a water temperature sensor error. The NTC thermistor, which monitors water temperature during the wash cycle, is sending a reading outside the valid range of 23°F to 217°F (-5°C to 103°C). The washer stops operation when this fault is detected to prevent improper heating. The cause is typically a failed sensor or a wiring connection problem.

You should not continue running the washer while this error is active. The fault occurs during the water-heating step, and if the sensor is not accurately reporting temperature, the water could be heated improperly. This can affect wash performance and, in a worst case, could create a safety concern. Resolve the error before resuming normal use.

If only the wiring connector needs reseating, there is no parts cost involved. A replacement NTC water temperature sensor typically costs in the range of $15 to $50 for the part. If the control board has failed, parts alone can run $100 to $300 or more. Professional labor charges will add to these figures depending on your location and the time required for diagnosis and repair.

Some steps are DIY-friendly, particularly checking and reseating the wiring connector to the temperature sensor after unplugging the washer. If the connector looks secure, testing the thermistor with a multimeter requires moderate technical skill but is manageable for experienced DIYers. Replacing a confirmed bad sensor is generally straightforward. Control board replacement is more involved and may warrant professional service.

Disconnecting power can temporarily clear the error code, but if the underlying sensor or wiring problem still exists, the code will return once the washer reaches the water-heating step of the wash cycle. A reset is useful for confirming whether the fault is intermittent, but it does not fix a failed thermistor or a damaged wiring connection.
