Many units have a clear plastic hose from near the top of tank, terminating near the water fill. This hose can become kinked, filled with water, or simply collapse from age. If yours is like this, use compressed air to blow into the hose, towards the tank,and clear the hose. If that fails, then the hose must be replaced or straightened to remove the kink.
