I'd wonder if the correct amount was put in after the last backwash or disassembly also. I have to backwash a couple times a year and I have a cover on all the time.

Seeing as the clowns who did the liner (they sucked) did it when they opened the pool during the liner replacement, it is very possible. I suspect I will need to close the pool in 2 weeks or so for the winter, is it ok to do the backwash when I open it? Or is it best I do a backwash before I close it?
I need to start reading up on what is involved with closing the pool, we originally were planning on having someone close it but I want to see if it is something I can do myself.
With my oversized DE filter I don't have to backwash during the swim season (early May to early October). During a typical season filter pressure only increases 1-2 pounds. At closing I break it down and give it a thorough cleaning. At opening I just have to add DE and it's good to go for the season.

I would not let your DE filter sit all winter with dirty DE in it. A coworker of mine did that and she said in the spring it was like trying to clean concrete out of the filter.
As I mentioned above, I'd break it down and thoroughly clean it at closing.
That video pretty much gives a good overview, though some of the specific recommendations are off IMO. For example, she said to open and clean the filter at least once a month. IMO, if you have to break it down that often you should get a bigger filter. Also, the amount of DE she says to use is way more than what is recommended by my filter's manufacturer (Hayward). See if you can find the manual to your filter and see what it recommends.
There are degreasers/scale removers you can use to clean the grids (I saw no mention of this in the video).
This is the lube I use for O rings;
