My only guess is that there must be a relay inside the control panel that (like many relays) arced ar one time and partially welded itself in the on position. Good quality relays are plated with a high temperature melting point metal to prevent this. Being LG is Goldstar (a Korean company) they most likely use the cheapest relays. To solve this issue the relay needs a hard knock to it. (Don't hit it so hard as to break the circuit-board) :)
Mine did manage to change from full-time running to shut off at a percentage but that doesn"t respond to set it and only shows the humidity present level. I am replacing and I will take it apart once I have a replacement. But knocking it does not help 1%

SOURCE: Runs all the time, not collecting water
I don't know your particular unit, but my guess is that the compressor is bad. If it is old, it may not be worth fixing.
SOURCE: Dehumidifier
Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.
Thank you for your allowing me to advise you on this issue.

SOURCE: Unit runs but water collects on the floor
The drain hole within the unit is most likely plugged up with an accumulation of crud. (Common problem). Depending on the make/model, you may be able to access that drain hole by simply removing the collection bucket. If not, then unplug the unit and remove the housing to gain access to the internal drain.
SOURCE: No water collecting, unit running
the collector base under the tubes just collects water and drips it through a hole into the water bucket. there must be a loose hose(if it has one) or the base collector or bucket has a crack, as they usually are plastic. also if the unit is sitting on a very uneven floor this will happen
SOURCE: Won't collect water
Hi,
There are many reasons for a dehumidifier
to not work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier.
Dehumidifier is running but no water is in bucket
