Kenmore Washer Error Code E42

E42 means the washer detected that the door is still locked after the wash cycle finished. The control board expected the door lock to release but received a signal indicating it remained engaged. This can be caused by a failed door lock assembly, a faulty lock switch, wiring issues, or a control board fault.

Forcing the door open is not recommended, as you can damage the latch, the door strike, and the door lock assembly itself, potentially making the repair more expensive. Always start by removing power for at least one minute to allow the lock to release naturally. If the door still will not open, a technician can manually release the lock using the correct access procedure.

If the door unlocks and the error clears after a power reset, you can attempt to run another cycle, but monitor the washer closely. An intermittent E42 that returns repeatedly is a sign that the door lock assembly or wiring is degrading and will need attention before it fails completely and leaves the door stuck locked again.

Unplugging the washer and waiting one minute is the recommended first step for E42, and it does resolve the issue in some cases involving temporary glitches. After restoring power, try opening the door again. If the door remains locked or the error returns on the next cycle, a component like the door lock assembly or wiring will need to be inspected and tested.

If the fault requires replacing the door lock assembly, parts typically range from $25 to $80 depending on the specific model, with professional labor adding $75 to $150 or more. If the issue is a wiring connection or a simple reset, costs can be minimal. A control board replacement, if needed, is the most expensive outcome and can range from $150 to $300 or more for parts alone.
