The valve with the black handle in your prior post is the selector for where the water goes. Turn off pump when changing the selector. Put it on rinse and turn on pump for a minute or two and it will back wash the filter grids helping to clean out any debris stuck in the fabric. You will then put back on filter setting and turn on pump and add DE to the skimmer.
You also want to make sure you turn the handle the same way each time. Always go clockwise or counter clockwise. Doesn't matter which you choose but choose one and stick to it. The rubber gasket inside can get caught and ripped.
This might help. The multiport handle says it's used with a "Pro-Grid" DE filter. These are instructions for a Pro-Grid. Not sure if it's exactly the same as yours but it's some place to start to understand how it works and what you should do to clean and maintain it. :lookhere: https://www.hayward-pool.com/pdf/manuals/ProGrid-DExx20.pdf

With a DE filter you will need a bigger box of DE. Make sure it's for pool use.
