Thank y'all soo much. Still haven't found a manual crank BUT I figured out the problem. Sigh. I kept hearing a faint clicking from the panel box-so of course I was convinced that was the problem but everything checked out. For whatever reason though I opened the tiny cupbard next to it where the water pump is & I could hear the clicking real good....I started wiggling wires around, got mad again (lol), hit the switch as I was walking out & Viola...it worked. Apparently when we replaced the water pump a couple days ago we must have moved/tapped the wires. but what's weird is that the wires seem to be running along with the wires to water pump wires along 1 of the water hoses so neither of would have ever guessed they didn't go to the pump.
Problem mostly solved....I still have to locate the manual crank for slide.
Again, thank y'all soooo much & I'm sure I'll be back for more advice.
