How to fix Electrolux dryer error E31

Start with the safest checks and work from simple to technical.

  1. 1

    Step 1

    1. Unplug the dryer from the power outlet.

  2. 2

    Step 2

    2. Open the dryer door and locate the two metal moisture sensor bars (Part 134786110) inside the drum, usually near the lint filter housing.

  3. 3

    Step 3

    3. Clean the surfaces of the sensor bars thoroughly with a cotton ball or soft cloth dampened with rubbing alcohol. This removes any film from fabric softener sheets or detergents.

    6. Access and replace the main control board, carefully transferring all wire connections to the new board.

If the code comes back

Do not keep replacing parts based only on the code. Repeat the safe checks above. If the fault remains, stop and arrange qualified service rather than ordering from the code alone.

What may be causing it?

  • Dirty or coated moisture sensor bars
  • Faulty moisture sensor
  • Damaged wiring to the moisture sensor

These are possibilities to investigate, not proof that one part has failed.
