Front panel removal

Unit malfunction. Dehumidifiers are designed to function within specific temperate ranges, usually between 50 and 80 degrees. Make sure that the ambient temperature of the room is within the range of your dehumidifier. Try not to run it continuously.

Pull the humidistat dial off. Remove two screws on the bottom of the front panel. Pull the panel off from the bottom. There are two tabs on the top that will come out when the panel is rotated approximately 45 degrees. There are two oil ports on the top of the motor. Reverse the process to rerassemble the dehumidifier.

Remove water collection bucket. Remove two screws now visible (previously covered by top edge of bucket). Front panel now has to be flexed a bit on the side to release it from the metal side panels, near the lower portion of the front panel, then panel swings up and un-hooks from top.

Push down on top of panel and pull out at bottom

Take the bucket out and remove the two (black colored phillips head) screws at the bottom of the front panel, just above where the bucket was. Push the bottom of the panel to the side a bit to release the retaining tabs from the metal side panels and pull the bottom of the panel forward to remove the panel from the top tabs, leaving wires attached. Put the bucket back in place and observe the coils while compressor and fan run for several minutes (5 to 10 minutes will do). If coils do not get cold, or only get cold over a small area, you have a refrigerant leak. A refrigerant leak is not economical to repair. Most dehumidifiers have a 5 year sealed system warranty, so round up your receipt and call LG with the model and serial number (located on a sicker behind the bucket) to get an exchange unit. Going from memory here, but I think you can reach LG at 1-800-256-0000.

After you remove the two screws, you just have to pull up on the front panel (gently). Use the vent slots for finger holds. I just did it 10 minutes ago.

It sounds like you need to check the drain under the cooling section. It can fill with dust, lint, cat hair, spiders, etc. and prevent water from draining into the bucket. First, unplug the unit. Don't do anything with AC power present. Then, remove the 2 screws under the front panel where the air filter slides up in and pull off the control panel. There are "snap" latches in the plastic near the top that can be (are) hard to undo, so be careful. You might want to have work gloves on because of sharp edges. Prying with a screw driver will cause permanent dents in the plastic. Also, there is a small, sleeved bunch of wires that goes up the left side to the operator buttons and display. Be careful not to damage it and the circuit board it goes to. Set the front panel aside, wire attached. There is no need to disassemble any of that. The drain is a small 3/8" hole in the black plastic floor of the cooling area at the front, right side. It seems to have a fitting for a hose that feeds through to the back of the unit. Clean any foreign material from it and everything else. Test it, with the bucket in place, by pouring some water in, if you want to. Then clean the dust off of everything so it looks new. Don't get the circuit board wet. Re-assemble, being careful with the front panel wire so it is not pinched and does not prevent easy removal/installation of the filter, and it should be OK.

I had the same problem (minus the cover issue) . To get the cover off, take off all visible screws. Slide a small screwdriver into the space between the back and the side cover. You will see a slight opening where the tabs fit in, you will need to carefully pry the tabs out. However, most likely your problem is with the front panel. You take the front panel off much the same way. 2 screws are concealed by the bucket. I had the same beep no display, thought it was the main pcb, which I ordered and installed. That did not fix it. I cleaned the display pcb, and jiggled the buttons, that seemed to fix it. I think the button to increase the humidity was stuck closed, as I could replicate the problem by holding that button down and then plugging in the dehumidifier. I would start by cleaning or replacing the front panel pcb, which is about $14.

The fall may have knocked out some wiring -- open the unit (remove back panel, then remove front by taking out screws inside) and see if any of the cables to the front panel or control board came out.

I dropped the water bucket by accident on the dehumidifier, and I have the same problem. Here what I found :
First, remove the water bucket and find the circuit diagram, it is very useful.

E1 code is related to the room humidity sensor, E2 code is related to the room temperature sensor and E3 code is related to the safety thermistor sensor. If you have one of these error code displayed, you will probably have to replace the sensor.

The humidity and temp sensors are located on the same board. To access it, remove the water bucket and you will see the 2 screws holding the front panel. Remove the screws, then gently prayed the front panel. Be careful, there is two plastic clip on the top of the panel and they are really easy to break. The board is located at the top right, under the cover. The safety thermistor is located on a pipe on the right side of the dehumidifier.
