Electrolux Washer E31 — What It Means & How to Fix It
E31 points to the electronic pressure switch — the part that tells the washer how full the tub is — and the control board is rejecting its signal.
What this code means
E31 means the electronic pressure switch that reads tub water level is returning a signal the control board considers out of limits, so the washer can't trust its water-level reading.
Documented for Electrolux front-load washers (EIFLW/EFL/ELFW series with an electronic pressure switch); on washer-dryer combos the meaning can differ, so confirm your model family in the manual.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Faulty electronic pressure switch | Common | No — technician job |
| Loose or damaged wiring between switch and control board | Occasional | No — technician job |
| Clogged or pinched pressure hose or air trap | Occasional | Yes — inspect the small hose |
| Main control board fault | Less common | No — technician job |
What you can try yourself
- Unplug the washer, wait a couple of minutes, then restart a short cycle to see if the code was a one-off.
- Check the small pressure hose running from the tub area to the pressure switch for kinks, cracks or water inside.
- If the hose looks fine and the code returns, a technician should meter-test the switch and its wiring before any part is replaced.
- Don't keep running cycles to test E31 — a bad level reading can let the tub overfill.
When to call a technician
- If water keeps running into the tub, unplug the washer immediately.
- If the code returns after a reset, stop and call for service.
- Don't run repeated cycles just to watch the code — it won't clear a failing part and can risk overfill.
Typical professional repair cost: $150–$350 typical including the part and labor
Frequently asked questions
Will a reset clear E31?
Sometimes for a one-off fault. If it returns, the switch, wiring or board needs a technician — a reset won't fix a failing part.
What does the pressure switch normally do?
It senses the air pressure in the tub and reports the water level to the control board, so the washer fills the right amount.
Can I test the pressure switch myself?
Testing it properly usually means removing panels and reading resistance with a multimeter — a job for someone with the manual for your model.
