What Does Error E31 Mean?

The AEG washing machine error E31 indicates an issue with the water level detection system. This error typically arises when the machine detects an insufficient or excessive water level in the drum. Common causes include a faulty water level (pressure) sensor or a blocked pressure hose/air chamber. Symptoms may include the machine stopping mid-cycle, refusing to continue washing, or failing to fill correctly.

Common Symptoms:

  • Machine stops mid-cycle and shows E31
  • Unit refuses to continue wash due to water level mismatch
  • May not fill correctly or detect incorrect fill level

Possible Causes

  • Faulty water level (pressure) sensor (medium)
  • Blocked or obstructed pressure hose/air chamber (medium)

How to Fix Error E31

DIY Fix Check basic water level related components

  1. Turn off and unplug the washing machine.
  2. Check that the inlet water supply is operating normally and tap is open.
  3. Inspect visible hoses for kinks or blockages.
  4. Access and inspect the pressure hose running from drum area to sensor — blow gently to clear any debris (if safe to do so).
  5. Ensure all external hoses/connectors are seated correctly.

Technician Only Inspect and replace faulty pressure sensor

  1. Disconnect power and water supply.
  2. Remove top or rear access panel to locate the pressure sensor.
  3. Inspect wiring harness, connectors, and pressure hose for damage.
  4. Test pressure sensor with multimeter to verify functionality.
  5. Replace pressure sensor if testing confirms failure.
  6. Verify operation by running a test cycle after reassembly.

Parts needed: Pressure (water level) sensor, Pressure hose / air chamber components

🛑 When to Call a Pro:
  • If error persists after checking and clearing blockages
  • If the pressure sensor or wiring appears damaged
  • If there are water leaks when accessing internal components
  • If you are not comfortable performing internal diagnostics safely
