The loose door latch is not a product defect or malfunction.
To support the easy opening/closing of the door, the door latch (lever) is designed to be slightly loose.
You can check the small device on the other side of the door handle.
For safety purposes
If the door of your washing machine closes easily, it will pose a hazardous risk to children, infants or pets due to a lack of air inside the drum.
For user convenience purposes
To ventilate the drum after using your washing machine the door latch is intentionally designed to keep the door slightly open.
(Do not close the door entirely)
