E40
Electrolux Washing Machine
Severity: ModerateWhat Does This Error Mean?
Electrolux E40 indicates a door lock fault — the machine cannot confirm that the door is properly locked before starting or during a cycle. The fix is usually clearing an obstruction from the door seal or resetting the machine.
Affected Models
- Electrolux EWF series
- Electrolux EWS series
- Electrolux EWT series
- Electrolux front-load washing machines
Common Causes
- Door not closed fully — laundry caught in the door seal
- Door lock mechanism (latch) worn or faulty
- Door hinge broken or door misaligned
- Washing machine control board error — temporary glitch
- Child lock activated — machine ignores door close signal
- Electrical fault in the door interlock circuit
How to Fix It
-
Open and firmly reclose the door.
Open the door fully and check that no clothing is trapped in the rubber door seal or between the door and the drum. Close the door firmly — it should click into place. Do not slam — apply steady pressure until you hear the latch click.
-
Check the door seal for trapped items.
Run your finger around the inside of the rubber door gasket. Small socks, bra underwires, and other small items frequently get trapped between the seal and the door, preventing a proper close. Remove any obstructions and try closing again.
-
Reset the machine.
Turn the programme dial to Off or press and hold the Start/Pause button for 5 seconds. Unplug the machine from the wall. Wait 60 seconds. Plug back in and restart with a new programme. This clears temporary control board faults that can trigger E40.
-
Check whether child lock is active.
Most Electrolux washers display a key or padlock icon when child lock is active. Child lock disables all button inputs including the door unlock signal. Deactivate by holding the designated button combination (check your model's manual — usually two buttons held for 3–5 seconds).
-
Inspect and replace the door latch if worn.
If the door closes but E40 persists, the door latch mechanism may be worn and not triggering the interlock sensor fully. Inspect the latch hook on the door and the strike plate on the drum opening for wear or damage. A replacement door latch (interlock) costs £15–£40 and is a straightforward repair.
Frequently Asked Questions
Can I reset an Electrolux E40 error myself?
Yes — an E40 error caused by a temporary control board glitch or a door that wasn't fully closed can be reset simply by unplugging the machine for 60 seconds and then restarting. If the error returns repeatedly, the door latch mechanism or the door interlock switch needs replacement — a repair a competent DIYer can do with a screwdriver and a £20–£40 part.
