I think my pool filter system back fired

[solo]

My pool is on a timer ,when my system shut off it blew the lid for the skimmer basket, shot water in the air.
now motor is running but there is no suction, no water moving.
I never heard of anything like that before.

I primed the pump, restarted motor, everything seams ok so far.
still do not know what caused the backfire.
I checked for a clog, found nothing, this was just odd.
