Check your levels and make sure it isn't already full. If it's not full try reducing the water pressure of the hose you're using. There is a vent next to the fill hole in the gravity fill. Normally the water would flow into the tank and when it is full it comes back at you out of the smaller vent hole. When things are working normally you should feel/hear air coming from the vent hole.
If you do find the tank full and you didn't fill it I would drain it and flush with a little bleach and water then drain that and re-fill.
