See: "If your Mac doesn't go to sleep when you expect" here > If your Mac doesn't sleep or wake when expected - Apple Support

I've looked over the "If your Mac wakes unexpectedly", "If your Mac doesn't go to sleep when you expect" and the "If the previous steps don't work" sections and tried all the items without any result.
What does Wake reason: EC mean?

offer resolution to your issue; if nothing else, a re-install of OS X may help.
MacBook Pro keeps waking up from sleep - see entire two page thread
and note the methods suggested by contributor Linc Davis. Unfortunately
few are around to decipher results he suggests, but check into it anyway.
{The plain Wake Reason EC does not show a contributing factor, though in
some instances, there would be additional coded info there, on that cause.}
Had you checked any other contributing factors in the system settings; such
as 'wake for Bluetooth' that may get external signal from ?? to keep it awake?
Also it would not hurt to try those 'other' items in the cited Support article
more than once; the NVRAM reset should make the Mac chime 2 or 3 times.
And the System Management Controller SMC won't hurt to try it again, again.
And if nothing else, start in OS X Recovery, & download then reinstall the OS X.
If you have a backup and time machine archive, you could restore the computer
but be wary of using a backup or migrate what may be damaged goods into a
fully new system installation; as a migration can bring in old issues.
In any event...
Good luck!
