I normally clean out the DE cartridge once a month, and after cleaning the psi would be in normal range of 8-9.  Lately, after I clean it, suprime and start pump, psi increases after 30-45 minutes.  

Ininsoecyed cartrdige and they're clean, however are 12 years old and may need replacements.  One of the cartridges had a tiny Year and I found small broken piece when inspected.

It sounds like you need to replace the DE elements. What is the make and model of your DE filter?

Where do I find the info? It's a Hayward and has the 8 fan shaped filaments inside.

i can't find the original papers as the previous home owner had installed the system.
