I have a goldstar dehumidifier and it is leaking behind the control panel. It runs fine. Because of this leak it fills the bucket (instead of running out the drain tube to the floor drain). Trying to dump the water from the bucket leaves me with water still in the machine behind the front cover.

Your bucket full switch may be defective. If you are capable, bypass it since you are draining to another place other than the bucket.

If yours has a button/switch to turn on a pump, that will redirect the water to the drain. Sllee

We came home to this problem the other day, water all over the basement, leaking out the bottom left side, nothing in the collection basin but plenty would spill out if I tipped the unit forward. After searching the web and these forums I theorized that the coils were frozen. I let the unit thaw. No luck. I removed the faceplate and discovered thick, wet silt had filled the internal collection plate and was clogging the drain. I stuck a pipe-cleaner through the drain and the problem was fixed. Took some paper towels and cleaned the whole thing. Works like new. I assume the unit will need to be cleaned regularly to keep it going. To remove the faceplate, unscrew the two phillips' head screws under the faceplate along the sides, then take a flat head screwdriver and pop the tabs holding the face on, one tabe along each side. There are also two tabs on top, but you don't need to mess with those, as they simply act against gravity. Whole thing just clips back together after cleaning. I have no idea if this voids the warranty.

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.

Take cover off. First check the fuse on the circuit board. If it's blown replace it. That should get the motor running, the motor might be or is going out. If the motor is bad you'll have to replace the motor. If the fuse is good and the motor is good, unhook the wires on circuit board that go to the humidity control switch. If the unit comes on with the humidity control switch unhooked, you'll have to replace the humidity control switch. Sears has them for about $11.50. Hope this helps.
