Whirlpool Washer Error Code F3 E2 — Temperature Sensor Fault
What this means
The F3 E2 error code on Whirlpool washers indicates the water temperature sensor (NTC thermistor) is sending an incorrect or out-of-range signal to the control board. This can be caused by a faulty thermistor, damaged wiring between the sensor and control board, or a failed main control board. The washer may stop mid-cycle or refuse to start when this code appears.
Alternate codes: F3E2
Step-by-step fix
4 stepsUnplug the washer and locate the sensor
Disconnect power from the washer. The temperature sensor is located at the bottom of the outer tub, accessible by removing the lower front access panel. Look for a small probe inserted into the tub with a two-wire connector.
Have a towel ready — a small amount of water may drain when you access the bottom of the tub.
Test the temperature sensor
Disconnect the wire connector from the thermistor. Set your multimeter to ohms and measure the resistance across the sensor's two terminals. At room temperature (about 77°F), the sensor should read approximately 50,000 ohms (50K).
If the reading is 0 ohms (shorted) or infinite (open), the sensor is defective and needs replacement.
Inspect the wiring harness
Follow the wires from the sensor connector back toward the main control board. Check for any damaged, pinched, or corroded wires. Secure any loose connections.
Vibration during wash cycles can loosen wire connectors over time — push each connector firmly to reseat it.
Replace the temperature sensor
If the sensor is faulty, twist it counterclockwise to release it from the tub housing. Install the new sensor with a new O-ring gasket, reconnect the wiring, and reassemble the access panel.
Apply a thin layer of silicone lubricant to the new O-ring to ensure a watertight seal.
When to call a professional
If replacing the temperature sensor and checking the wiring does not clear the error, the main control board may need replacement, which is best handled by a certified technician.
