How do istop the tcl portable air con leaking water

As you probably know, Air conditioners condense the moisture out of the occupied space, as the room air passes over the colder coils.
That water has to drain away into a drain, or a bucket -- or something!

So-- How is the water designed to drain away?
and what is interfering with that path?

There are the obvious causes, like mold, or a bug, or dirt, etc-- blocking the drain hole-
Or possibly sediment filing the condensate line trap--
Are you sure these are all clear, and open?

But one that is often overlooked, is the fact that a fan might be creating a slight vacuum in the area where the drain line exits the rain pan--- and the water can actually be prevented from draining, until the fan shuts off (removing the slight vacuum)-- is that possible in this machine?

Or when you open up the machine, is the drain pan still filled to over flowing?
Can you use a mini Toilet plunger on the drain, to help unblock it?

Give me some more clues, and I'll try to help you trouble shoot deeper into the problem.
