External water tank

Just recently my air conditioner will not fill the external water tank. This means that it fills up faster. This unit has also started to leak slightly from the bottom (I have had to put a tray under the unit). Can anyone tell me why it would do this? Is there anyway to fix this problem? Thanks in advance

Re: external water tank

Dear ziba1--posted the same problem two days ago and it doesn't appear to be on the site yet. Anyway, picked away at this again today (literally took the machine apart) and found the problem to be a clog in the drainage system. This explains why your external tank will not fill and why there is a leak--the drip tray under the compressor is not draining due to the clog in the drainage system. I fixed this simply by taking a narrow device and gently scraping out the drain hole of the drip tray (which is located just below the compressor...the compressor is located on the same side as your air filter). After successfully cleaning out this drain, I proceeded to flush the water out thoroughly with water. Give it a try--worked for me. I had all but given up and had already set up an appointment to have it serviced. Cheers

Do I have to fill the tank under my mobile aircon CEG Model 8000R/C before I start the unit or is a catchment tank ?? Thanks in anticipation

Air conditioners unit produce moisture, if it is not drained to outside it will spill over to floor. CHECK FOR A drain line to outside.

Air conditioner will run for about 3 hours then stops because its full - it seems to fill constantly fast??

Hello my name is Heath it will be my pleasure to assist you. This is normal depending on the amount of humididty in the air the faster it will fill. What you could do is run an external drain line to drain the water while its filling so you don't have to keep dumping the fill pan.

I have the same model and if you have been running the dehumidifier the internal water tank will fill with condensate water. You will need to unplug the black plug (in back of unit) to release the pints of water it has accumulated in the tank. Be sure to have a pan under the plug as it will drain immediately. Do not tip the portable unit if you need to put in a shower stall to drain, as water will leak out of the internal water tank into your unit. Hope this helps.

First time start up

The external tank is to collect humidity (condensate) from the coil as it cools the room. You need to empty the tank when it is full, not fill the tank yourself. Hope this helps.

My danby air conditioner/dehumidifier model dpac 8399-4 leaks water all over the floor and never fills the holding tanks what can I do to fix this problem?

Probably needs cleaning. I assume it is on a level surface. Water drips from the evaporator coil into a collection tray of some type and then drains into the holding tank, this tray is either broken or the outlet is plugged.
Good Luck,

External tank not filling

I recently encountered the same issue. First off, with the external tank installed is there an icon on the display panel indicating the tank is installed?

No? Then the two sensors are not picking up the magnets in the the "arms" on the back of the tank. It's a poor design for sure, on my unit the tank does not sit flush enough to the back of the AC, if I held the tank firmly to the back the icon would come on. I just used a bit of cardboard at the bottom of the support tray to press the tank firmly to the back of the AC.

Theory is as the external tank fills up, water will run into the "arms" and raise the magnets tripping the switch which tells the unit it needs emptying. But the magnets in the arms are not strong enough if they are not close enough to the sensors. So my cardboard solution lasted only one tank.

I ended up getting some flat neodymium magnets (that I scavenged out of a hard drive), and taped to the sensor that had the gap. I wouldn't recommend doing this to both sensors since it would eventually overfill, only one sensor needs to "trip" for the compressor to turn off.

If you answered yes to the first question (the bucket icon is there), then it's most likely the pump not working on the internal reservoir, or something related to that. Can't help you there...

Water tank fills up every 3hrs

The amount of water that is getting extracted from the air in the room is based on how humid the air is. The good news is your unit is really getting quite a bit of moisture out of the air and as such, is working well to cool your room.

It is working as designed. You may want to see if you can connect a hose to a drain port (if yours has that included) to let the unit room longer without the need to drain the condensate (water) every 3 or so hours.

Hope this helps and best regards!
