From the sound of your question, you need to get a pool man to
check it out. It may or may not have been ruined. Most likely
you developed an air leak and air in the pump stopped it from
pumping, but if it ran long enough it may have damaged things
inside.

Have you tried filling the basket with water and restarting it?

I've had it happen, what everyone has referred to as air locked. The only
remedy was to unplug pump, set to backwash, let the water start to flow on
gravity alone. Start pump, allow to run on backwash, then reset it to
filter. No matter what I tried I could never get it to restart pumping
without this ritual. Hope this helps.

Thanks for all the info folks. I had the pool guy come out this
morning. Turns out the impeller is broken. The bad news is that the
pump is attached to the housing with four bolts and one of those bolts
just spins. Meaning that the threaded insert in the housing is junk.
The pool is 20-yrs old and I don't know how old this pump is so I am
getting a new pump & housing assembly and keeping everything else as
spare parts.
Thanks again for your input.

That was the right thing to do IMO, and at 20 years it's probably
the second or third pump if all went normally so it's likely time
for another motor at least if you're north, for sure if you're
south. BTW, it's HayWard, not Hayard. One thing though:

The bolts that fasten the pump to the impeller part (motor) are
not threaded in Haywards: They are, in my experience, bolts with
a nut on the other side. So I wonder if you misunderstood
something, or ... .
