Model-Specific Repair Notes

FAQ
Can the lock problem be just the door strike?
Yes. The strike can wear out or misalign and keep the lock from engaging.
Why is the washer dead even though power is on?
If the lock system does not confirm closure, the cycle may not begin.
Should I replace the lock or the board?
Start with the lock and latch system unless multiple electronic symptoms suggest the board.
Can I force the door open?
It is better to follow the model’s safe release method rather than forcing the door.
