Safety first: Disconnect power before adjusting hinges or latch components.

- Step 3 – Inspect latch bracket (qualified persons): Remove the control panel to view the latch receptacle inside the cabinet. Ensure it is not bent or cracked.
- Step 4 – Replace worn parts: Replace the door latch hooks or complete door assembly if they are worn. Replace springs if present and weak.
- Step 5 – Test operation: Close the door and start a short cycle to confirm it remains latched.
