Usually, this one has a simple answer:
The flap at the bottom of the tank isn’t sealing properly. Simply, remove the top of the tank and flush the toilet, keeping an eye on the rubber flap. If it doesn’t close completely, the float ball trigger will never be activated since the water won’t reach the fill line. If that is not the issue, a service call is in order.
