Whirlpool Washer Error Code WATER TEMPERATURE SENSOR ERROR

This error means the water temperature sensor (NTC thermistor) is sending a reading outside the accepted range of 23°F to 217°F (-5°C to 103°C) during the heating phase of the wash cycle. The washer stops the heating process and displays this code to alert you to a problem with the temperature sensing circuit. The issue most often involves the sensor itself or the wiring connected to it.

When this error is active, the washer has already stopped the water-heating function, which reduces the risk of overheating. However, continuing to run the machine without resolving the fault means the water will not reach the correct temperature for your selected cycle, and the underlying wiring or component issue should be addressed before regular use resumes.

If only the NTC temperature sensor needs replacement, parts typically range from $15 to $50 depending on the specific model, making it one of the less expensive washer repairs. If the main control board is the cause, parts alone can range from $100 to $300 or more, and professional labor will add to that total. Getting an accurate diagnosis before purchasing parts will help avoid unnecessary expense.

Many DIYers can address this error by first unplugging the washer and inspecting the sensor connector for loose or corroded terminals. If the wiring checks out, testing the NTC sensor with a multimeter to verify its resistance is within specification is the next step. Replacing the sensor is a straightforward repair for someone comfortable with basic appliance disassembly, but if the control board is at fault, that repair is more involved.

Unplugging the washer for a few minutes and restoring power may temporarily clear the error code, but if the NTC sensor or its wiring is defective, the fault will return as soon as the machine reaches the heating step of the wash cycle. A reset alone does not resolve the underlying hardware problem and should not be treated as a fix.
