What a technician must be able to justify
Technician visit
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.
Door lock check
What they doThe technician checks the lock and, with the washer unplugged and a multimeter, its connection and wiring against Zanussi's specification.
They must show youthe measured lock value against the specification or the visible fault.
In writingthe failing part, its part number if replaced and the reason.
Door test wash
What they doAfter the repair, the technician closes the door, runs a programme and checks it locks, washes and unlocks without E40.
They must show youthe full programme without E40.
In writingthe test carried out, the result and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Door closing
- Who:
- you.
- How:
- open the door, make sure no laundry is caught between the seal and the glass, and close it firmly until it clicks.
- Result that matters:
- whether the washer starts with the door properly closed.
- If it starts without E40:
- it was the door or trapped laundry.
- If E40 continues:
- check the load.
- Evidence to keep:
- note of what you found.

Amount of laundry
- Who:
- you.
- How:
- if the drum is very full, take some laundry out and close the door again.
- Result that matters:
- ruling out the load pushing the door.
- If with less laundry it closes and starts:
- it was overloading.
- If with a normal load E40 continues:
- check the child lock.
- Evidence to keep:
- note of the load.

Door child lock
- Who:
- you, with your model's manual.
- How:
- if your washer has a door child lock, turn it off with a coin or similar object as the manual shows.
- Result that matters:
- ruling out the lock stopping the door closing.
- If it was on:
- once off, close the door and try again.
- If it was off and E40 continues:
- call the service; the lock may need replacing.
- Evidence to keep:
- photo of the lock before and after.

What it means
Zanussi says E40 and E41 indicate that the washing machine door or lid is not properly closed or detected. The washer will not start washing until it confirms the door is shut; trapped laundry, overloading or the child lock can prevent it. If none of these explains it, Zanussi says the door lock may be faulty and need replacing. E40 alone does not confirm the lock is broken.

- Overloaded drumPossible
A drum that is too full pushes the door; with less laundry it closes easily.

- Faulty door lockPossible
If it clicks shut, with no laundry in the way, no overload and no child lock, and E40 persists, the lock may be faulty.
