How to Fix It
-
Open and close the door firmly to check the physical latch.
Push the door until you hear a solid click. Feel for resistance in the latch.
-
Check the door seal (gasket) for any clothing trapped inside.
Even a sock caught in the seal can prevent the door from fully closing.
-
Unplug the washer for 60 seconds and plug back in.
A power reset can clear electronic glitches in the door lock circuit.
-
Restart the cycle and listen for the lock engaging.
You should hear a click followed by the lock light (if equipped) turning on.

If dE3 persists, the door lock assembly likely needs replacement.
A technician can replace it in about 30–60 minutes.
