My pump goes off every morning at 9:00. I went outside today at 12:30 to find that my water wasn't moving and my sweep was at a stand still. I went and checked my gear and the filter had pressure but the window in the pump was fogged up. I shutdown via the timer then steam blew out of the pump basket housing. I let it sit for a few minutes then put some cool water in the basket and it started back up and flow resumed. Did my pump not prime or something?
