Common questions
What does E30 or E31 mean on a EdgeStar laundry center?+
a door lock failure.
Is the door stuck shut?+
It may be, but do not force it with water inside, since that can break the latch.
Can I fix it myself?+
Checking the harness is a home job, and a lock replacement is a modest repair for a confident owner.
Is the lock an expensive part?+
A door lock assembly is not among the dearer parts of a washer.
Why will the door not open right after a cycle?+
The lock stays engaged until the drum has stopped and the water has drained, so give it a few minutes and check that the drain hose is not kinked. A door that is still locked well after that, with no water in the drum, is the fault the code describes.
