DE Filter no filtration

Hayward Micro-Clear DE 4800 filter
Replaced manifold, pads, upper O ring and cleaned the whole thing but it’s not filtering. Backwashed a bunch. We have very little pressure at the return.
Pump pressure is normal when it’s re-circulating but not when going through the filter.
Im not sure if it’s worth replacing the rest of the guts of the filter or if there’s something else we should do.

Little pressure back at the return jets could indicate a restriction in the filter itself. Perhaps overloaded with organics. Your PoolMath logs haven't been updated for a while. Can you post a full set of test results? It's best to rule-out chemistry right off the bat before you go nuts tearing apart the filter any further.

We haven’t balanced anything yet because we’ve had one problem after another since we opened this summer.
First we couldn’t get someone to power vac, then we had to wait to have the filter cleaned, then replaced the filter manifold l, then ordered a new valve. Tried to see if it was the pump but the one we had was the wrong size.
I will test when I get home later.
