Code CH 01 is showing where the humidity level is suppose to be. The machine turns on & shuts off immediately

CH 01 Indicates that water collection tank is full and needs to be removed & emptied. Turn the unit OFF and unplug it, before removing the bucket.

Actually, it's probably doing what it should. Let me explain: Dehumidifiers run until they have lowered the humidity/moisture level to where you have the humidity extraction level set. At that point, the unit shuts OFF, until senses the humidity level has risen above where you set the level and it turns ON again. That doesn't mean the bucket will always be full when it shuts OFF. It may turn ON & OFF many times before the bucket is full. Watch for the Bucket Full Light to illuminate. That's when the bucket is FULL and needs to be emptied.

Hope this helped you understand how the unit works.

Hi,

Here is a tip that explains what can be happening to make the dehumidifier showthat the bucket is full when it is not.

Depending on which mode you have the unit set on, will determine if it shots OFF entirely or the fan continues to run. In the Constant or Continual mode, the compressor will turn OFF, once the humidity extraction level has been reached. But, the fan will continue to operate, in an effort to keep the air circulating, so that if the humidity level rises, the compressor will turn ON and start extracting again.

In Timed Mode (usually 2 hour or 4 hour) , when the compressor turns OFF the fan does too.

Hope this helped you. Please let me know. Thanks.

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.

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.

In answer to all your questions. If it's working properly, Yes.

I believe it is a water tank code. Re-seat the tank, unplug wait 15 seconds and replug the power cord and see if this resolves the error.

Background relating to other possibilities.
When the water bucket reaches its capacity, the bucket switch opens to shut off the dehumidifier. If the bucket switch fails while it is open, it will prevent the dehumidifier from running. To determine if the bucket switch is defective, use a multimeter to test it for continuity. If the bucket switch does not have continuity, replace it.

I have a Comfortaire BHD501 dehumidifier. A couple weeks ago I noticed ice building up on top of the unit,so I unplugged it to defrost. I plugged it back in and it worked until I noticed the "CH" "01" code. It would run a few seconds then shut off with that code showing. I took off the front of the unit and noticed rust on some of the metal parts. Then I took the cover off the circuit board for the front read out. I noticed corrosion on some of the solder points. When I looked closer at the plastic cover for the circuit board I noticed a small burn mark. The water from the melting ice must have run behind the cover and shorted out the circuitboard. At this point I don't know if new boards are available.

I had the same problem, and I wound up calling LG's customer support line. The rep I spoke with says that the "CH" code means that the internal thermostat is not able to accurately read the air temperature, and the unit will require servicing.

She gave me a couple of numbers for local folks, and I'll call them in the next day or so, but I'm thinking that this may not be worth the repair, unless it's pretty cheap: I bought the unit for under $100 less than 9 months ago, and I'm not eager to shell out a bunch of money to get it repaired.
