DE Filter Problem

What would cause a DE filter to quickly lose suction power? Normal right after regenerating/pumping as well as right after adding new DE then loses suction. Pump seems to be working fine. Any thoughts??? It always works perfectly:(.

Unfortunately, yes. Bump every ten minutes, replace DE every hour or so when a bump only lasts 2 or 3 minutes.
Probably want to open it up and thoroughly wash the fingers after the pool is clear.

I hope you are performing the SLAM Process as written, so as to speed things up as much as possible.
