What Does Error Code E42 Mean on a Electrolux Washing Machine?

Door lock device failure — door will not lock.

E42 fires when the control board commands the door interlock to engage but never receives confirmation that the locked state was reached. The board monitors the PTC/solenoid lock feedback line; if the signal is missing within the expected window, it aborts the cycle before filling. This distinguishes E42 (lock never confirmed) from E41 (door reported open) and E43/E44, which involve unlock or lock-circuit control faults rather than a failed engage confirmation.

Models affected: Front-load Electrolux washers with an electronic door interlock, including models such as EFLS627UTT and ELFW7637AT
What owners report: Owners commonly report E42 appearing right at cycle start, often after the door was closed a bit softly or a laundry item pushed against the seal. A firm re-close plus a brief unplug reset frequently clears it, but if the code keeps returning the lock assembly itself is usually the culprit.
