Weak Water Flow

[adman]

I have a starbright 50 DE filter. I have clean filter fingers and have put fresh DE back in the filter. When the filter is first turned on the water flow to the pool is good and strong. After 5 minutes of the filter running on high the water flow diminishes to a trickle. When this happens I can shut down the filter, bump it, and then restart and the flow is back to normal for another 5 min. I have new hoses, and have greased up all the rings to the filter. Any insight into what the problem could be?

What does your water look like? Are you putting to much DE powder in? the filter might need to be chemically cleaned.

I have the same problem. Did you find out why this is happening?
