I have 2 problems and I think problem #1 caused problem #2....but need your professional opinion.
Problem #1 diagnosed by pool repair co.
My Jandy electrical panel/board/relay/electrical failure caused the filter pump motor (2HP challenger motor) to receive only 120v instead of the needed 220v. this caused the motor to flicker on and off randomly every 45-90 seconds for 4 hours during programed run time. Since this happened during the day when I wasn't home, I was unaware of the problem and am not sure how long this went on. After a long weekend away, I came home to DE covering the bottom of the pool.
Problem #2 MYSTERY: DE blown back into the pool, covering bottom of the pool.
Is it possible with problem #1 the pool filter system could not filter properly and the DE built up in inside the filter and it accumulated on top of the manifold and the top of the filter screens, crushing the screen edges from the weight of the DE build-up causing gaps, and the increased pressure inside caused hairline fractures in the manifold and these two things caused DE to be blown back into the pool?
Your expertise is important as the insurance company will only cover problem #2 if it is related to problem #1. Why would there be DE on pool bottom??
