My dehumidifier is only about a year old and the bucket full light keeps blinking. i turn it on, it sounds like its going to kick on but shuts off a second later.

the float switch above the tank might be stuck. or broken

I had the very same problem with my Zenith ZD300 dehumidifier. After getting no help from the manufacturer and realizing that it was going to cost $45 just to figure out what was wrong with it, I dismantled the dehumidifier myself in search of a solution. I suspected it was the humidity sensor, so I ordered the part off Repair Clinic website (repairclinic.com). It cost $18.20 plus shipping. AND IT WORKED!! I was so relieved that I wouldn't have to buy a new dehumidifier. It's been running for a day now, so we will see. Here's the website link:

Hi, Sounds like the circuit board...they often will just do that...IF you can get one it will be half the cost of a new unit...
There are many reasons why a dehumidifier willnot work or collect water.

lcd reads ch 1 shuts down bucket full light blinks red

Try re-seating the bucket. I have found some LG models that if not seated all of the way will sometimes keep running and think the bucket is not full even when it is. On the models that I have seen do it the problem is usually the left side of the bucket not engaging all of the way. When you reseat the bucket, feel where the bucket meets the dehumidifier on each side and make sure they are even. If one feels like it is sticking out further than the other and you cannot push it in any more pull the bucket out and try and reseat it again until both sides are flush with the dehumidifier. If you found this solution helpful please rate it.

Thanks - Tech101
