Pump worked then stopped?

[prizepoet]

I started my pump for the first time this yr, it was fine, I added DE, it went in fine, then I noticed the return valve was turned on its side, water was coming out OK, but I shut the pump to fix it, turned pump back on and now it just hums, no other action is taking place, what does that mean? Is it burned out?

Sounds like the pump is locked up. You may be able to free it up by turn the armature over by hand and then powering the pump back up.
