    My LG LHD45EL has stopped working. The display reads CH 01. The "Bucket Full" light blinks every 3 seconds. The bucket is bone dry. I unplugged it for a few minutes, plugged back in. Fan engaged for about 3 seconds, display read "on", and then it went back to CH 01 and shut down with "Bucket Full" blinking again.

    The bucket is empty. I have also cleaned the filter and CH 01 keeps appearing. I turn it on, it runs for a second or two....and CH 01 keeps showing up.

The temperature sensor on teh suction return line from the coil has drifted out of spec and needs to be replaced. This sensor is part of the sensor assembly which plugs into the control board. I purchased the part from Appliance Factory Parts on line, cost about $30, an hour or 2 to change depending on your mechanical level, it is easy to do. For Goldstar DH404E part # was 6877A30013M, they are same part for many models but if this is not the right # for your model just get the right "sensor assembly" for your model and change it out. It consists of Temp/humidy sensor in coil, temp sensor in suction return line, and plug harness that goes to float switch. My uni is running like new again.

Emptied bucket fine. Went to turn back on starts to work and then shuts down right away

Make sure that the water full detection switch is not stuck in the full position. Its a plastic piece near the top side and when the water level gets high enough it floats the piece up to turn off the unit. It can sometimes get misaligned when changing the bucket and stuck in the off position.

The "bucket full" light blinks even after the

Eddie, turn the unit OFF & unplug it. Then remove the bucket and check the float valve in the top of the bucket. It may be stuck in the 'UP' position or is broken. When reinstalling the the bucket, be sure that it fit's "squarely" from top to bottom in the bucket holder and is making firm contact with the bucket safety removal switch on the rear wall of the bucket holder.

Hope this helped you and thanks for choosing FixYa.

Turn the Master ON/OFF Switch to OFF and unplug the unit from the wall. Remove the bucket and check inside the top of the bucket for a Float Valve (some Haier unit have them) It may be stuck in the UP position. If so, jiggle the arm of the float vale to get it to return to the DOWN position. Reinstall the bucket again. However, leave the unit OFF & unplugged for 10 minutes, before plugging it back in and turning it ON. Whether you have a float valve of not, the 10 minute time out, should have given the unit's electronics time to reset themselves.

Hope this helped you troubleshoot and solve the problem.

Our LG LHD45EL dehumidifier stopped working. The bucket full light flashes, though the bucket is empty and the filters clean. The display shows CH01. The manual does not say what CH01 means. Any...

I don't know what CHO1 is either! My husband and I had the same problem a couple years ago. We just ended up buying a new one.

The bucket full light is on and unit will not run. Unit has hose adapter in use.

Look inside where the bucket goes in at the top right hand side is the bucket switch. Hold it in and start the unit. If it runs the arm on the switch must be bent SLIGHTLY until it makes contact with the button and the lite goes out with the bucket in.

My LG dehumidifier does not turnoff when full and overflows

make sure the float in the bucket isn't binding on something. The float actually activates a button that you can see when you remove the bucket. pull the bucket out and see if the unit cuts off. Maybe the button is stuck.
