Hi, When I tried to start my dehumidifier, it won't work and indicate CH 01. The bucket is totally empty and in good place. What this CH 01 means?

Your model is no longer in manufacture or available. However, I was able to locate the Owners Manual for you. It does not list a CH 01 Error Code, but does list other reasons why your unit want turn ON.

http://www.lg.com/us/support/product/support-product-profile.jsp?customerModelCode=LHD45EL&matchedModelCode=1000001989&searchEngineModelCode=LHD45EL&targetPage=support-product-profile&initialTab=documents#

In the past, I have recommended turning the Master ON/OFF Switch to OFF and unplugging the unit for 12-15 minutes. This will give the unit time to hopefully, reset itself. Then Plug the unit back in and turn the Master ON/OFF Switch to ON. Set the humidity control as you normally would. If it successfully reset itself, it should operate normally.

If you continue to have problems, contact LG Customer Support at 800-243-0000.

Hope this helped you to solve the problem.

Air con indoor unit is flashing 6 times out door is off

Please specify the make and model of your unit.
If this is a LG inverter model.
The six flashes of the indoor unit light indicates a CH 06 alarm.
This alarm state indicates that the indoor unit pipe temperature sensor has measured a temperature out of range or the unit is protecting itself from this low temp state. Indoor unit coil temperature to low. Should it have reached a temperature of -5°C for longer that 30sec it will switch the machine off.

It could indicate that the unit refrigerant charge is too low or the sensor has gone out of calibration.

It should measure 5kΩ @ 25°C
