What Does Error E31 Mean?
The Westinghouse Dryer error E31 points to a malfunction in the moisture sensor, which may cause the dryer to stop mid-cycle or fail to complete the drying process. This error often arises from abnormal feedback detected by the moisture sensor, leading to incorrect moisture readings.
Common Symptoms:
- Dryer stops mid‑cycle with E31 displayed
- Drying cycle fails to complete normally
- Potential incorrect moisture detection
Possible Causes
- Moisture sensor detecting abnormal feedback frequency (sensor or circuit issue) (medium)
How to Fix Error E31
DIY Fix Basic moisture sensor and lint system check
- Turn off and unplug the dryer.
- Clean the lint filter and exhaust vent thoroughly to ensure airflow is not restricted.
- Inspect the moisture sensor bars inside the drum for residue — clean them with a soft cloth and mild cleaner if needed.
- Restart the dryer and check if E31 reappears.
Technician Only Inspect and test moisture sensor and control circuitry
- Test the moisture sensor with a multimeter per service manual specifications.
- Check wiring harness connections between the sensor and control board.
- Replace the moisture sensor if out of specification.
- Verify control board inputs/outputs related to the moisture sensor circuit.
Parts needed: Moisture sensor assembly, Wiring harness/connectors, Control board (if sensor circuit faults persist)
- If cleaning and basic checks do not clear E31
- If internal wiring or sensor tests show faults
- If other error codes appear concurrently
