How to stop portable air conditioner leaking water

I heard that some portable air conditioners can leak water from the unit after being operated for about an hour or so if they are not on a level floor.
I solved this with my DeLonghi air con after discovering the floor my unit was on had about 1 - 2 mm difference from one side to the other. By buying a small builder's liquid level (like you use to keep a line of bricks aligned) I used a small piece of wood (ruler thickness) under one side of the air con and no more leaks! Hope this helps someone. Kez, Perth WA

We purchased a Whirlpool portable air conditioner in 2005 from Best Buy. Near the end of last summer the air conditioner started leaking water. We started using it again this season and it is still leaking. When my husband drained the water out of it, the water came out of the upper part of the back side of the air conditioner and no water was coming out of the drain at the bottom. When it appeared to be empty, we plugged it in and used it again and it continued to leak water on our carpet. Do you have some reasons why it would leak and can you offer suggestions to fix this problem?


Check to see if the drain is blocked by particles/debris of any type. Also make sure that the unit is level--as level as possible. I have my Whirlpool Portable AC in 4 inch bed risers so I can drain it really easily. I slip under a small low rise pan and drain it every two days or so when it is running. Mine leaked when I tried to incline it backwards to make it drain faster. As soon as I leveled the unit the leak stopped and water again came out the hose. These units must be kept level to prevent leaks so now I always do that.

Water leaking from portable air conditioner


Sounds like the drain line is blocked you would have to take this unit apart in order to check this. I would use a can of air to blow out the leakage. Also make sure the unit is level

Water leaking from portable air conditioner


First, make sure the unit is level. If so, you have a blockage or kink in the drain tube. Careful inspection should reveal any blockage, & you may be able to poke it thru with a piece of coathanger wire. Don't use excessive force, any block should be easily freed.
