What Does Error F12 Mean?
The Whirlpool Washing Machine error F12 indicates a heating circuit fault, specifically a communication failure between the control board and the motor control unit. This error typically manifests when the washer fails to heat water to the required temperature, causing cycles to stop or not progress. Common causes include a faulty heating element, issues with the wiring or connectors in the heating circuit, a malfunctioning temperature sensor, or a failure in the control board heating relay.
Common Symptoms:
- Washer displays F12 during a wash cycle requiring heated water
- Water does not heat to the selected temperature
- Cycle may stop or fail to progress when heating is required
Possible Causes
- Faulty heating element (heater/TEN) (medium)
- Wiring/connectors in the heating circuit (medium)
- Temperature sensor/thermistor fault (medium)
- Control board heating relay or related component failure (medium)
How to Fix Error F12
DIY Fix Basic checks and resets
- Turn off and unplug the washing machine.
- Wait 1–2 minutes, plug back in, and restart to see if F12 clears.
- Ensure the selected wash cycle actually calls for heated water.
Technician Only Inspect and repair heating circuit
- Disconnect power and access the heater assembly (usually at the bottom front of the washer).
- Test the heating element for continuity with a multimeter; replace if open circuit or out of spec.
- Check all wiring, connectors, and harnesses related to the heater and thermistor; repair any damage.
- Test the temperature sensor/thermistor and replace if faulty.
- Inspect heating relay on the control board; replace board or relay if defective.
Parts needed: Heating element (heater/TEN), Temperature sensor/thermistor, Main control board or heating relay, Wiring harness/connectors
- If you are not comfortable working with electrical components
- If basic checks (power reset) do not clear the code
- If multimeter diagnostics identify complex circuit or control board issues
