Chances are you have a torn grid inside, sometimes debris will cover the tear while it's running, then when the pump shuts off the debris settles to the bottom of the tank. Then when the pump turns back on, it shoots DE and debris through the tear until something else plugs it. Tear the filter down and inspect the grids, replace as necessary.

I'm getting DE back in my pool from the 4820 filter


One of two things can cause this. Either the spider gasket is bad or there is a rip or tear in one or more of the filter grids.
P.S.
(the spider gasket is inside the valve you turn to backwash filter)

De powder coming back into pool water from filter


make sure your grids are properly seated and if you have a multiport valve, take it apart and make certain your spider gasket is in place and not distorted. That is the only other reason DE would return into the pool. If you have a slide valve, make sure your o-rings inside are in good condition and properly lubed.

Need to reassemble the D.E. filter


All D.E. filters are basically the same. There are two plastic manifolds. One attaches to the bottom of tank by threads or bolts. The other plastic manifold goes on top, and ussually has small holes in this manifold for stainless rods to run through.All fabic looking materials(grids) run between bottom manifold, and top manifold.All grids must be washed free ofD.E.(diatomacus earth). Place bottom manifold on solid ground and begin plugging grids into large holes in manifold so they form a circle, this sometimes takes two people. Place top manifold on other end of grids in a simular fashion.Gently turn assembled filter to its side while holding together, and run ss rods through small
holes in bottom manifold, i n between grids , and through small holes in top manifold. Secure rods with ss washer and nuts, until snug but not overtightened.
