Dehumidifier 53550 says bucket full and it is brand new. By manually pushing the indicator behind the bucket I can get the unit to start, but soon after it says the bucket is full again. After manually pushing the indicator, I put the bucket back in but I want to run it with a hose

SOURCE: runs for a couple of minutes and then stops

Try cleaning out the air filter using cold water. I did not even know the unit had one until I had the same problem. Pull out the bucket. The filter is located where the front top edge of the bucket would be located if it were in the instrument. Remove it by pulling straight down. It may be taped to the instrument for shipping purposes. According to the manual, this should be done every month. I have had the machine since Katrina and this is the first time I have had a problem. Hope this helps.

SOURCE: dehumidifier won't turn on

Make sure the buicket is seated all the way. Sometimes it doesnt fully engage on the left side. If it is then it may need to be serviced. LG has a 5 year warranty on these models. They usually will tell you of a service center nearby which will service it free of charge since it is under warranty. If you do not live near a service center they may ship you a replacement and you send your old dehumidifier back to them. Make sure you have your reciept when you contact them so they can verify it is under 5 years old.

Many just attach the hose at the reservoir; from your description, Haier apparently has a separate location. Check that the point that the hose attaches has an opening (many don't, they expect you to drill it). It should then drain through gravity. Check to make sure that no part of the drain hose is higher than the bottom of the reservoir, otherwise it can't drain. It won't siphon because each time the the tank empties, the suction is broken and the siphoning can't continue.

Same problem with Goldstar model DH404EY7 -- stop code 01 on startup, bucket full light blinks (drains to floor).

Replaced the main controller board to fix it.

For my model dehumidifer the part # is 6871A20888A, and cost $77.44 (not counting shipping) from Appliance Factory Parts. The Appliance Factory Parts web site also provides parts breakdown (exploded parts diagram) diagrams and service manuals in PDF form.

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:
