Here is a manual for your machine, in case you don't have one:

Here's what one person said about the code on

Unit keeps saying bucket full with nothing in it and it will have a CH 01 code come up on the display. NO reference to it in manual. Call customer NO service and they say to take it to a repair shop 1 1/2 hour drive away. I would not recomend this unit to anyone unless you like to keep buying new ones every year or so.
Not good news, but someone said the unit has a 5 year warranty, so you might check into that.
Another person said check the sensors:
--Shoddy craftsmanship:
1. The sensor that stops the unit when the water reservoir is removed is flimsy, often it does not detect that the reservoir is inserted back, one has to fiddle with the reservoir till the sensor finally "catches on", but then every now and then the mechanism will lock and will be unable to detect that the reservoir is full, resulting in a water spill.

It doesn't seem like anyone has figured out this code, but it has to be a sensor, or bad part, if you can just figure it out.
Good luck, hope some of this helps, and thanks for using FixYa.

LHD45EL Dehumidifier won't run

This will need to be serviced. LG has a 5 year warranty on these models. They usually will tell you of a service center nearby which will service it free of charge since it is under warranty. If you do not live near a service center they may ship you a replacement and you send your old dehumidifier back to them. Make sure you have your reciept when you contact them so they can verify it is 1 year old.
