Although Apple is about to release the next version of the newly renamed macOS in the coming days/weeks, I expect this posting will be useful not only for OS X El Capitan or Yosemite, but also likely for the next version of macOS Sierra (10.12).
If you are already running OS X El Capitan (10.11) and need to reinstall the OS or install a fresh installation to a new hard drive (or partition), you may find as I did that downloading the OS X El Capitan (10.11) from the Mac App Store is simply not working. What I experienced after clicking the Download button was a busy indicator spinning indefinitely and the download never happening. I tried this on several different Macs with the same result. Of course, all my Macs were already running OS X El Capitan (10.11) so my attempts failed consistently on all three.

After contacting Apple Support, my first call ever by the way, apparently Apple now only allows each Mac to download the OS X El Capitan/Yosemite installation file one time per machine. This is what I was told by Apple Support. Also, when looking at my Purchased apps in the Mac App Store the OS X El Capitan did not allow me to download it and showed disabled “Downloaded” button instead, even though the OS install file already on my Mac was unusable. Delete this file had no affect on the ability to re-download the OS installation file.
However, Apple Support instructed me how to accomplish this another way – a legal and supported option. And that is by booting your Mac into Recovery Mode (or OS X Utilities) menu. Here are the steps.
