Usually that's a signal that the filter is not getting enough water going through it. Make sure you squeeze all the air out of the sponge before you slide it on the intake and if that doesn't work, try taking it off and see if that solves the problem. If it does, I would not use the sponge anymore unless you want to have to replace your filter sooner than normal due to overheating the motor.
Hope this helps
