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

  1. Turn off and unplug the dryer.
  2. Clean the lint filter and exhaust vent thoroughly to ensure airflow is not restricted.
  3. Inspect the moisture sensor bars inside the drum for residue — clean them with a soft cloth and mild cleaner if needed.
  4. Restart the dryer and check if E31 reappears.

Technician Only Inspect and test moisture sensor and control circuitry

  1. Test the moisture sensor with a multimeter per service manual specifications.
  2. Check wiring harness connections between the sensor and control board.
  3. Replace the moisture sensor if out of specification.
  4. 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)
