DIY Fix Check and reset basic conditions

  1. Ensure the door is fully closed and latched.
  2. Unplug the washer from power for a few minutes and then reconnect to reset the control board.
  3. Check if any water remains in the drum; if so, run a drain/spin cycle or manually drain via the pump filter access.
  4. Try opening the door only after power reset and ensuring the cycle has fully stopped.

Technician Only Inspect and replace door lock assembly

  1. Disconnect the washing machine from power.
  2. Access and test the door lock assembly for mechanical or electrical failure.
