Model compatibility: Electrolux reuses codes across series and control generations, so E31 may mean something different on another appliance or platform. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
An Electrolux washer displaying E31 is reporting electronic pressure sensor error. Start with the simple checks that are safe to do from outside the appliance, then stop if the code returns. Do not replace parts from the code alone; use the full model number and the observed symptoms to confirm the cause.
Read this display narrowly on the documented control platform: electronic pressure sensor error. A symptom such as incorrect water-level behavior can fit more than one cause, including pressure sensor problem or air-tube or air-trap restriction.
This record is based on the Electrolux technical/service documentation for the EFLS617SIW, EFLS517SIW, and EFLS417SIW control generation. The same display code can have a different meaning on another Electrolux platform, so confirm the full model number before applying this diagnostic path.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Turn the washer off and disconnect power for several minutes.
Check that the drain hose installation is correct and that the washer is not siphoning.
Look for obvious overfilling or water remaining in the drum.
Do not open the cabinet or disconnect the pressure hose unless you are trained to service appliances.
Important safety warning. Stop user-level troubleshooting if the code returns after one safe reset/check cycle or if the washer shows leaking, overheating, electrical, or mechanical symptoms.

When to call a technician
If E31 returns after the safe checks, schedule repair. A technician can follow the model-specific diagnostic path and test the components associated with electronic pressure sensor error.
If one safe retest does not clear E31, keep the displayed code and model information for the service visit. Mention whether incorrect water-level behavior, because it is relevant when checking pressure sensor problem.

It indicates electronic pressure sensor error. Confirm the full washer model because diagnostic meanings can vary between control platforms.
You can try the safe external checks listed above and one power reset where appropriate. If the code returns, repeated resets are not a substitute for diagnosis.
Avoid continued use if there is leaking, overheating, an electrical symptom, a locked door, or abnormal drum movement. Otherwise, correct any simple installation or load issue and test once.
