Whirlpool Duet door will not UNlock

Missed the 2 error codes that were flashing when it stopped, but door was locked and door-locked light was flashing. Unplugged machine for a few minutes, then when re-plugged it in, it drained itself with door-locked light still flashing, and door would not unlock. Unplugged again, and now when plugged in, it tries to drain itself (hear pump motor ) with no water remaining in machine. Now, pump will continue to try to drain, but no other lights or buttons work except for the door-locked light flashing and the door remains locked. Can not turn it on or off with power button. UPDATE. Model number is WFW95HEDW0. Took off top of washer and was able to access pull-tab on locking mechanism and opened door. Still sounds like pump continues to run even with the door open, and power-on button still does not turn anything on.
