Should be opened once a month

Depending on the machine model, the shape and location of this filter will be in different places. For most front-loading washing machines, the lint filter is located on the outside of the washing machine, making it easy to see. For top-loading washing machines, the lint filter is usually located right inside the washing drum.
Washing machine drums usually have a removable bottom, and you will see a small plastic cover. Pry this plastic cover up. Then you will see a screw in the middle. Now, use a screwdriver to remove the screw and lift the bottom up. Lift the bottom out, pour out the dirt and scrub it clean. For the inner washing drum, use a cloth to wipe it clean. Then you can reassemble it as before.

It is best to clean it once a month. That will help your washing machine clean and the clothes after washing smell good. It is also a way to maintain the washing machine to last longer. Cleaning the washing machine is a way to help your clothes smell good and avoid bacteria. Occasionally you can also use white vinegar in the washing machine and use a light spin to clean the washing machine. Removing the washing machine residue box is often forgotten, especially in families without men, this requirement is often overlooked. Remember to clean it regularly, ensuring that your clothes will smell better.
