What Does Error Code E31 Mean on a Electrolux Washing Machine?

Pressure sensor not communicating with the control board.

E31 fires when the control board reads the electronic pressure sensor's signal as out of range or absent, meaning it can no longer verify tub water level. This is a communication/signal-integrity fault at the sensor input, usually from a bad sensor, a blocked or kinked air-bell hose, or a corroded connector. It differs from related level codes like E35 (overfill/high level) and E13 (leak or drain-related), which reflect specific water conditions rather than a lost sensor signal.

Models affected: Electrolux front-load washers with an electronic pressure (water-level) sensor, including models such as EFLS627UTT and ELFW7637AT
What owners report: Owners commonly report E31 appearing mid-cycle with the door staying locked and water left in the tub. A quick unplug-and-wait reset sometimes clears a transient glitch, but if it returns, checking the clear air-bell hose for kinks or debris is often the easy win before replacing the sensor.

What Causes Error Code E31?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Pressure sensor fault 45% of cases
  2. 2
    Pressure (air-bell) hose blocked or kinked 25% of cases
  3. 3
    Wiring/connector to sensor faulty 20% of cases
  4. 4
    Control board fault 10% of cases

How to Fix Electrolux Washing Machine Error Code E31

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Reset the washer

    Unplug for one minute to clear a transient fault.

  2. 2

    Inspect the pressure hose

    Check the clear hose between the sump air-bell and the sensor for blockage or kinks.

  3. 3

    Check sensor wiring

    Reseat the connector at the pressure sensor and inspect for corrosion.

    ⚠️ Unplug before inspecting.
  4. 4

    Replace the pressure sensor

    If the hose and wiring are good, replace the sensor.

Frequently Asked Questions

Can I keep using my Electrolux Washing Machine when error E31 appears? +
It is not advisable. The washing machine may still power on, but running it while E31 is active can worsen the sensor fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes E31 on a Electrolux Washing Machine? +
Across reported Electrolux washing machine repairs, the most frequent is pressure sensor fault (45% of cases), pressure (air-bell) hose blocked or kinked (25%), then wiring/connector to sensor faulty (20%). Check them in that order before replacing any parts.
E31 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E31 fault; if it returns, the sensor problem is still present. Move on to the physical checks — reset the washer, then inspect the pressure hose — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Electrolux Washing Machine error E31? +
A DIY repair typically runs $35–$80 in parts, versus $150–$300 for a professional service call, so handling it yourself saves around $115. Expect the work to take roughly 30–60 minutes.
Which Electrolux Washing Machine models show error E31? +
E31 is documented on Electrolux front-load washers with an electronic pressure (water-level) sensor, including models such as EFLS627UTT and ELFW7637AT. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
