Error E31 in Electrolux washing machine

Error E31 in Electrolux washing machine

Error: E31

Description: Fault related to the water level system. It commonly indicates a damaged level switch/pressure sensor, incorrect water signalling (overfilling) or problems caused by excess foam.

Causes

• Damaged or faulty level switch / pressure sensor.
• Clogged tubes, ducts or pressure hose (blocked air path).
• Worn or damaged membrane in the pressure chamber.
• Faulty solenoid valve causing incorrect filling.
• Excess foam from too much or wrong detergent affecting sensors.
• Loose or damaged wiring and connectors to the sensor or electronic board.
• Faulty electronic control board.

How to eliminate E31

Checks to perform

1. Disconnect mains power before any inspection.
2. Visually inspect the pressure hose and tubes for kinks, blockages or water ingress. Clean or replace if blocked.
3. Check the membrane and pressure chamber for damage or debris.
4. Test the level switch/pressure sensor: verify continuity or replace if malfunctioning.
5. Inspect wiring and connectors for corrosion, loose contacts or broken wires. Repair or reseat as needed.
6. Check the inlet/solenoid valve operation to ensure proper filling and no continuous flow.
7. Remove excess foam: run a rinse/anti-foam cycle or use less detergent in future cycles.
8. If all above are OK, test or inspect the electronic control board for damaged components or burnt traces.

Repair actions

• Replace the level sensor/pressure switch if tests show it is defective.
• Clean or replace clogged tubes, ducts and the pressure hose.
• Replace a damaged membrane or pressure chamber components.
• Repair or replace faulty wiring and connectors.
• Replace the solenoid valve if it fails to control water inlet correctly.
• Replace the electronic control board only after ruling out sensors, valves and wiring.
• Use recommended detergent amounts to prevent foam-related false signals.

Notes for dryers and combined models

Some Electrolux drying or washer-dryer models may show E31 with similar symptoms (water-level or foam-related alerts). The troubleshooting steps above apply, with emphasis on cleaning ducts, checking pressure hoses/membranes and removing excess foam. Always consult the model-specific manual for differences.
