What Does Error Code E40 Mean on a Electrolux Washing Machine?

Door not closed or door lock failure.

E40 fires when the control board never receives confirmation from the door interlock that the door is both shut and locked before a cycle begins. The board waits for the lock switch to close its circuit; without that signal it halts to prevent a wet start. This differs from E41, which points more specifically to a wiring or lock-circuit fault, whereas E40 most often means the door simply isn't latched or laundry is bridging the seal.

Models affected: Front-load Electrolux washers with an electronic door interlock, including models such as EFLS627UTT and ELFW7637AT
What owners report: Owners commonly report E40 appearing right at cycle start, often after overloading when a sock or shirt corner keeps the door from seating fully. A firmer push until a solid click resolves it in many cases; if it persists with a clean, empty gasket, the lock assembly is the usual next suspect.

Frequently Asked Questions

Can I keep using my Electrolux Washing Machine when error E40 appears? +
You often can for a cycle or two, but the door issue behind E40 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.

E40 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E40 fault; if it returns, the door problem is still present.

This is a moderate job — a multimeter and some disassembly are usually involved.
