Electrolux Washer Error Code E40

E40 is a door fault code that indicates the washer has detected a problem with the door being open or with the door locking mechanism. It is a parent code that covers sub-faults E41, E42, and E43, each representing a more specific failure within the door lock system. The washer will not operate while this code is active because running with an unsecured door poses a safety risk.

No, you should not attempt to bypass or continue running the washer while E40 is active. The error exists specifically to prevent the machine from operating with an unsecured or unconfirmed door lock, which could allow the door to open during a spin cycle and cause water spillage or injury. Resolve the fault before resuming use.

Repair costs depend on the root cause. A door lock assembly replacement typically ranges from around $80 to $200 in parts and labor combined, depending on labor rates in your area. Wiring harness repairs or connector fixes can be less expensive. A control board replacement represents the higher end of potential costs, often ranging from $150 to $350 or more when including labor. Getting a specific diagnosis before committing to parts is recommended.

Some causes of E40 are DIY-friendly, such as clearing an obstruction from the door gasket or reseating a loose wiring connector at the door lock assembly. However, if the door lock module itself has failed, replacing it requires disassembling the front panel and working with electrical components, which is manageable for experienced DIYers but carries some complexity. If the control board is involved, professional diagnosis is advisable.

A power reset, done by unplugging the washer for a few minutes and restarting, may temporarily clear the code if the fault was caused by a transient signal glitch. However, if the underlying issue is a failed door lock component, damaged wiring, or a physical obstruction, the code will return as soon as the washer attempts to start a cycle and check door status again. A reset alone is not a repair.
