E-5 -Comms Error, check your wiring, remove external pumps. Split/Multi - check volts from terminal N to 3 = 0 - 65 Vdc, Multi V - 4 Vdc terminals 3 and 4

- Check your air filter at the indoor if clean.
- Check your evaporator fins if clean.
- Check if no icing in your evaporator and outdoor pipes.
- If your air filter and evaporator fins is clean and icing is present then your unit is under charge.
- When your indoor drips check your drain pipe if there are water comes out. If no water drain from your drain pipes then your drainage is restricted.
- Flush your drainage with water using your garden hose to flush out dirts from your drainage.

SOURCE: LG 18000 ac leaks water in the front of unit.

Hi,

the drain pan is either clogged or the unit is not mounted properly. If the drain pan is clogged simply clean it and the problem goes away. In the case of the unit mounting, check the angle of the unit and the drain pan inside, if it tilted to the front even just a little then water would leak. the drain pan should lean toward the drain and away from the front.

I hope this helps.

Ok. So first things first. LG have a reputation with all their products. THEY ARE ALL BAD! If you remember GoldStar, they are now LG. GoldStar had horrible products. Now this is what LG has. The fact that the filters are cleaned and the units are serviced is an abosulte plus and will provide the units with extra longevity. Now are these drains are they used for water drainage. If so the upstairs units shouldn't need them unless there is some sort of rise in the drain pipe.

Now to the noise. It seems like there is something which is causing the fan to make a noise. It could be loose bearing or a piece of the fan which has broken away causing it to hit the inside of the unit. Since it is on both units, it would be a generic problem with this series and unfortunately is what you are stuck with now.

To combat this problem, I would: ring LG and the company who installed them and demand that they be repaired and have a warranty on the repairs. Just a heads up, LG are really bad to contact should you have a complaint, so keep persisting that they be repaired free of charge since that they are still under warranty.

If you are not happy with LG or your installers response, I would remove the units and have another brand put in. I recommend Mitsubishi Heavy Industries and Panasonic. Both units are whisper quiet. In fact they are quieter that the LG.

Oh and that only reason why LG boast about their "whisper quiet-ness" is because that is probably the only good going for them - and thats' not even right!

I hope that I have helped you in some way. Good Luck!

SOURCE: LG split AC keeps displaying CO and wont't turn off with remote.

The "CO" indicates cleaning operation and can be switched of via remote button under flap, labelled AUTO CLEAN.
