Inside part of ac unit is filling up with water and also filling up the catch pan. I have already cleaned the drain tube and it is flowing good. What could be causing my problem?

No other trash in the line? Is there a condensate pump or just gravity?

It had a condensate pump but it works and I can't find any other trash in the line. I cleaned the trench that is suppose to send the water to the drain.

Could be a cracked or rusted drain pan under the evaporator coil. Could also be as simple as a plugged drain at the point where the pipe or tube connects to the unit.
