Error E38 in Electrolux washing machine

Description of error E38

Error E38 appears when the appliance does not detect a change in pressure or water level within a expected period. On Electrolux washing machines this usually means the pressure switch signal is not varying (often due to a blocked or damaged pressure tube). On some Electrolux dryers or washer‑dryers the same code can point to a water‑level / sensor or airflow/rotation related fault depending on model.

Possible causes

• Blocked, crushed or disconnected pressure tube leading to the pressure switch.
• Faulty pressure switch (membrane/diaphragm) or its electrical connections.
• Obstructed drain, vents or ducts preventing normal water/air movement.
• Worn or broken drum belt (in drum models) preventing rotation or proper sensor readings.
• Faulty motor, tachometer or related connections affecting rotation detection.
• Faults in the electronic control board or its connectors.

Recommended solutions

Follow these checks in order. Always disconnect the appliance from mains power before inspecting internal components.

1. Inspect and clean the pressure tube

• Locate the small rubber tube that runs from the tub to the pressure switch. If it is blocked, kinked or filled with detergent residue, air/pressure signals won’t reach the switch.
• Remove and clean the tube with warm water; replace it if cracked or hardened.
• Reattach securely and test the machine.

2. Check the pressure switch and membrane

• Verify the pressure switch connections are clean and tight.
• If possible, test the switch operation (manual vacuum or multimeter) or replace the switch/membrane if suspected faulty.

3. Clear ducts, drains and filters

• Clean the drain pump filter and any inlet/outlet hoses to ensure proper water flow.
• For condenser or vented dryers, ensure vents and ducts are free of lint and blockages that could affect sensors.

4. Check drum belt, motor and rotation sensors

• Inspect the drum belt for wear or breakage; replace if necessary.
• Check motor connections and any rotor/tachometer sensors that detect rotation.

5. Inspect electronic control board and wiring

• Examine wiring harnesses and connectors for corrosion or loose pins.
• If other checks fail and electrical faults are suspected, the control board or related components may require professional diagnosis.

Step‑by‑step quick troubleshooting

1. Turn off and unplug the appliance.
2. Visually inspect the pressure tube for blockages or damage; clean or replace it.
3. Clean drain pump filter and hoses.
4. Check drum belt and motor connections (if accessible).
5. Reconnect and run a short test cycle. If the code persists, proceed to test the pressure switch and electronics or contact service.

When to contact technical service

If you have performed the basic checks (tube cleaning/replacement, filters and hoses cleared, belt and connections inspected) and the error continues, contact Electrolux technical service or a qualified technician. Professional diagnosis is recommended when the fault involves the pressure switch internals, motor electronics, or the main control board to avoid further damage.

Notes for dryer or washer‑dryer models

Although this article is focused on the washing machine, some Electrolux dryers and washer‑dryers display E38 for related sensor or water/air movement problems. For those models apply the same basic checks: clean tubes/ducts, inspect drum belt and motor connections, and verify pressure/level sensors and control board connections.
