I have a LG dehumidifier, Model LD450EAL (similar/replacement for LHD45EL). This model has electronic controls (touch panel on/off and settings and digital humidity display) Recently it has started overflowing -- it does not shut off soon enough and the bucket gets too full. It does eventually shut off when the water is right at the top of the bucket. When I pull the bucket out I get a lot of water sloshing and falling on the floor (carpet).

There is a red switch behind the bucket that senses that the bucket is in and turns the unit on. It seems to be working and turning the unit on/off. There is also a float mechanism in the bucket which I assume activates the red switch when the bucket is full. However, there seems to be no way to adjust anything to ensure it turns off at the right water level.

Also, I've heard some of these units have an electronic water level sensor, but I can't see anything readily.

Does anyone know if this unit has a sensor or is it just a float activated switch? And how does one adjust it to shut off sooner?


Thanks.

Can you add a small piece of styrofoam under the float?

Thanks, I guess I can try that. I suppose you mean glue it to the bottom of the float?

1.6.3 MICRO SWITCH
The micro switch assembly, which is located on the drain pan of inside unit, automatically shuts off the dehumidifier when the
bucket is full (note, the Auto Shut Off lights, to indicate bucket must be emptied). The bucket replaces in its place, the unit again
turns itself on.


The diagram indicates that the only shutoff is the microswitch behind the bucket. This implies to me that the weight of a full bucket may cause the bucket to tilt sightly and close the switch.
Check that the unit is on level ground (you don't live on a leaning mountain do you?) , check that there is nothing obstructing the bucket from rocking into the switch.

That is all I got. Good luck

if that's the case... you could add some weight to the Bucket (internal or external)

If that is the case, why is there a float?
First, do no harm.
