AEG washer E40: door not locked
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
E40 means the door/lid was not confirmed closed and locked. Preserve the full display and model, then use a trapped garment, overload, mechanical child lock and the audible latch click to choose the next branch before any part or paid repair.
Safety first
Stop and check this first
- Stop immediately for water near electricity, smoke, burning smell, abnormal heat, damaged cable or repeated breaker trips. Close the water tap when a leak is possible; sealed water, heat and mains circuits are professional-only.
Safe checks you can perform
- Capture the decision evidence
- Run the one discriminating check

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Evidence-led AEG handoff for E40
What they doA qualified technician should test load obstruction, door alignment, latch, mechanical child lock, harness or control, using the exact model/PNC and the recorded result for a trapped garment, overload, mechanical child lock and the audible latch click.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

Capture the decision evidence
No special tools
Procedure
Photograph E40, the complete message and model/PNC. Record the failed programme stage and a trapped garment, overload, mechanical child lock and the audible latch click. Do not clear the history repeatedly.
Stop immediately for water near electricity, smoke, burning smell, abnormal heat, damaged cable or repeated breaker trips. Close the water tap when a leak is possible; sealed water, heat and mains circuits are professional-only.

Run the one discriminating check
No special tools
Procedure
Remove trapped laundry, reduce the load and close the door normally until it clicks. Check only the manual-described child lock; never force the latch or bypass its switch.
Stop immediately for water near electricity, smoke, burning smell, abnormal heat, damaged cable or repeated breaker trips. Close the water tap when a leak is possible; sealed water, heat and mains circuits are professional-only.

Stop at the result boundary
No special tools
Procedure
A trapped item or overload resolves externally. Correct closure without a lock indication selects the latch/alignment branch; a locked door that still reports E40 selects wiring/control service. If the same result returns after this one controlled pass, stop rather than chaining resets or cycles.
Stop immediately for water near electricity, smoke, burning smell, abnormal heat, damaged cable or repeated breaker trips. Close the water tap when a leak is possible; sealed water, heat and mains circuits are professional-only.
