The FL error usually means that there is excess water in the drain pan. Look for the drain plug cap at the bottom of the back of the air conditioner. Remove the cap and tilt the air conditioner so that any water in the drain pan will run out. If the room is extremely humid and the air conditioner is set to Cool, this is normal. To reduce the water level issue, set the fan speed to Low. If the air conditioner is in the Dry (dehumidifying) mode, try setting it to Cool. Alternatively, consider using a hose if your unit allows for a continuous drain.
Unplug the air conditioner for at least 10 seconds to reset the unit if the error persists. If the drain pan is dry or the error recurs before more water fills the drain pan after the reset, then the air conditioner needs service.
Please add a comment with the model number of the unit if you need help finding the drain pan cap. I hope this helps.

If the drain pan appears empty, try tilting the air conditioner in several directions to see if there is a blockage preventing the water from reaching pan. If this is the case, the problem is with the evaporator, that isn't a consumer level repair. Otherwise the problem is with the sensor. Cindy Wells

The 'water ?' rule usually indicates a problem with drainage. To fix this, you can check the drain pan under the evaporator coils, remove any obstructions on the drain pipe, and make sure the unit is level. Cleaning or changing the air filter can also help. If you can't find your manual, you can usually download it from the official LG website using your air conditioner model number. For additional help AC repair service

Some days ago my air conditioners showed me the same problem and I checked it but everything was perfect and I didn't know what to do. I thought that there are some problems with mechanisms and I called the socool.sg. They came and in 20 min repaired it and they told me that the problem was in the drain pan because it wasn't put in the right mode. Now it works perfectly.
