Greetings LilN,
Check the door latch and hinges, and confirm the door is securely attached to the dishwasher for smooth operation and to prevent any potential issues. Let me know if you need further assistance!
After installing the dishwasher inside the cabinet, check if the door opens and closes freely with no interruption with the cabinet.
Please see page 28 under "Securing the dishwasher" on the notes section on the 2nd bullet and page 37 under "STEP 13 Completing the installation" on the caution section. Of the manual.
