On my LG window AC Md. LWHD1009R, I cannot find a drain hole to let the water out. The back bottom of the pan was filled water containing a rusty sludge, but the heat exchanger coils are aluminum, so it must come from another source.( I have a wooden shutter built over my windows because of hurricanes-nails? ) Is this unit supposed to drain, because I bent down one place to let the rusty sludge and water out. Its properly mounted with the back lower than the front, and I've had no problems with water inside the wall in the house or outside, or wet carpet.

Here is the link to the manual:

Here are those particular instructions:

Compressor Indicator

The " " icon will light up on the control panel display when the compressor turns on. The " " icon will turn off when the compressor shuts off.

Emergency Condensate Holding Tank

When the room temperature is low and the indoor humidity is high, the air conditioner may not be able to evaporate some of the moisture fast enough. When this happens, the water will accumulate in an emergency condensate tank inside the unit. Once the emergency condensate tank is full, the unit will automatically shut off and the " " will appear on the control panel display. To empty the condensate tank, unscrew the screw plug at the bottom back of the unit. You will need a small pan, approximately 1" high to catch the water coming out of the condensate tank. Once the condensate tank is drained, the unit will begin working within a few minutes. The emergency condensate tank holds approximate
ly 1.5 Liters of water.

Another option is to purchase a small hose from a hardware store that can fit around the 5/8" drain plug on the back of the unit and drain the unit into a gravity drain or larger pan for continuous drainage.

To resume operation quickly, empty the water container according to the following steps:

1. Turn the unit off. Do not move the unit when the water container is full.

2. Place the drain pan accessory under the drainage port at the back of the unit.

3. Remove the screw plug from the drain hole. The condensate water will drain out automatically. When the drain pan is full, screw the screw plug back onto the drainage hole to stop the water flow. Empty the drain pan. Repeat until all the water is emptied.

Once the water container has been emptied, screw the plug back onto the drain hole. Do not allow the
water to drip continuously into the drain pan, as it might easily overflow.

Hi,

Self-defrosting refrigerators dispose of the water generated during the defrost cycle, usually via a tube or channel that directs the water to a pan at the bottom of the refrigerator. From the pan, the water normally evaporates. .

If the tube or channel is clogged or obstructed, the water backs up and leaks into the inside of the refrigerator compartment. Then the water builds up at the bottom, inside of the refrigerator. When the water has built up for a time it may spill out of the front of the door opening. To fix this problem, clear the drain tube or channel and allow the defrost water to flow down to the drain pan.You can use a hair dryer and remove the ice buildup

Make sure the drain holes in the bottom are clear, clogged drain holes will cause the pan to fill and condensation to be picked up by the fan.

When your refrigerator defrost the water runs into a drain pan in the bottom/underneath the refrigerator, You will need to first unplug and remove contents from freezer and proceed to remove the air tower in the center of the back panel, underneath the evap. coil in the center is a hole that leads to the drain and it is iced over and the water is not able to flow.What i do is get a hair dryer (be careful not to melt the plastic) and defrost/melt the ice. You will need a towel to start and once you think you have the ice removed get some hot water and pour in the trough to make sure it flow's to the drain pan. When the flow is good put the part's back and make sure the refrigerator is level from side to side and slightly tilted towards the back (front to rear)!

I posted the answer as a comment but the problem is the drain pan is under the cold radiator which is on top and it drains over the hot radiator which in turn drains into the pan that will hold water. When the top pan gets jammed up from lent then it drains down the other side of the hot radiator and it goes all over the floor. See the comments I put on the first answer. I posted this because I too bought a brand new Automotive aluminum pan until I figured this out

Here is a thought, received by me from a AC mechanic recently. Window ACs no longer actually drain concensate. Rather, the water is caught in a pan with the idea it will evaporate back into the outside air. The reason for this is the dripping water frequently resulted in the growth of algae below the unit resulting is unsightly stains and sometimes, slippery conditions. Evidently, there were a lot of complaints about being 'dripped on' also. So, AC manufacturers don't put drain holes in the bottom any more. If the pan over fills, it will spill out of many makes. If you want yours to drain, put a hole in the bottom.

Like I said, just a thought.

Thanks for your question @ FixYa.com

Part of the problem may be, that you don't maintain enough tilt down on the back of the unit. 1/4" to 1/2" is generally enough to drain the water to the rear of the drain pan. Some drain pans have a hole near the rear of the drain pan. They can be hard to find, if they're clogged, because the clog blends in with the drain pan. Others may have a **** in the corner of the drain pan, rather that a hole.

If you are unable to find the drain hole to unclog it and you're feeling really lucky, you can always drill a 1/8" hole in the rear corner of the pan and create a new one. However, the unit must be unplugged and the pan must be almost dry, before attempting this. In addition, you must be extremely careful when drilling this hole, so as not to pierce any of the mechanical parts above it. In other words, you must be in total control of the drill.

Hope this helps you troubleshoot and solve the problem.

p2 means the bottom pan is full, you need to drain the bottom, small valve on the back bottom in the middle

you have a blockage in the drain tube, remove panel back of freezer..you will see ice build up...melt ice with hair dryer/heat gun...you will see a pan below evaporator...melt ice in pan...dry water up in pan with paper towel...now you should see a hole in pan that leads to drain tube...pour some hot water in pan..wait a couple minutes..mop up water and repeat this step 2-3 times....once you have done this find some flexible curatain wire or electrical wire..poke down the hole until you see the water drain..now it is clear..put back panel back and you are good to go. the reason you see water in the fridge is because the water has been leaking down the vent instead of the drain hole...If you need any further assistance please feel free to comment again. good luck!

Remove contents of fridge and check the drain line running down the top back of the back of fridge and follow to lower section of fridge (usually a back ledge or under the crisper sections) and locate a small round drain hole. Also, check to see that the drain collector (funnel looking thing at top back of fridge section) is located under the freezer defrost drain opening, to allow water to flow through the fridge into the drain pan under the fridge.

If something has obstructed the drain funnel, path, tube, or lower drain hole, remove the blockage to allow water to drain into underneath of fridge into drain pan for proper evaporation of water produced from the usual daily defrost cycle of fridge/freezer.

If that is not the problem, it could be that you have a leaking water supply line for your ice maker and you'll need to see if the freezer is allowing excessive water to flow out of the ice maker into the fridge section.

Another simple check/solution is that the fridge is not properly leveled, meaning that the front of the fridge should be slightly higher than the rear to allow for proper drainage and self closing of the front doors. This will help keep the water flowing in the built in channels and drains.

A perfectly level fridge isn't the right way to install most moveable refridgerators, while built in fridges (Sub Zero, etc.) are designed for plumb and level installations for proper functioning and use.
