What is a code CH 01 - Comfort-Aire BHD-501 Dehumidifier

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.

CH 01 usually indicates that the filter is dirty and needs to be removed and cleaned. Turn the unit OFF and unplug it, before removing the filter. Never operate the unit without the filter in place.

Thanks for choosing FixYa.

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.

Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Dehumidifier is running but no water is in bucket

Had same problem in 2008. Had to replace Evap Thermister board and sensor. Parts $120 Labor $50.00.
I am not an expert. Good Luck!

Had same problem. Ordered and installed new bucket switch. That solved the problem.

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.

Change the sensor assembly and all will be fine, about $30 from Appliance Factory Parts on line store, about an hour to do, all that is needed is Phillips screw driver to take unit apart.

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.
