It was working then it stopped working; but the motor still runs. And the tank was low. Sounds to me like it has sucked in some debris which has stopped the pump working ie stopped the valves working properly. I would take it out and service it by giving it a good clean - almost certainly it will revive. If there's debris in the tank then an in-line filter will help, but really you need to clean it/them out as well.
