The unit does not remove any water. I took the outside case off and the bottom copper line (just before the end of the tubing to the left of the fins of the coils is freezing up. The coils themselves don't even feel cold.

Hi! My home dry 660 collects water but also has started leaking onto carpet? Is this a big fix? It is probably about 10years old!

not that big of a job ! it just needs a good cleaning out, start by unhooking power and then remove outer case , look inside at area that has lots of fins !! fine aluminum ones !! there should be a water tray just below the fins ! im betting this is well garb'd up with yuk!! take a 50/50 water bleach solution (gloves would be a good idea too) and work some f this around in the tray till it loosens up , remove with old towels or rags (throw em away) and find the drain hole in the tray that allows the water to drain into collection pan and poke down it with the end of a old pencil to clean it out as well (don't use metal) don't forget to clean your fan blades off too before reinstalling cover and leveling unit before reconnection power

Zenith Model ZD300YO 30 pt Dehumidifier Humidity setting panel reads 01/bucket full light flickering on and off- will not run, new unit

Take out bucket. Remove front cover two screws bottom left and right. Just inside lower left is a wiring harness with a clamp. Pry off and clean rust from clamp and tubing it attaches to. (if you put the bucket in and hold sensor between fingers the humidifier will start to work) Reattach clean sensor to clean copper tubing.

I have a Goldstar 305 unit and have been very happy with it for 4 or 5 years. Three days ago I noticed it was running very loudly and for much longer than it usually takes to fill the bucket. The bucket...

The problem you're having sound like the drain tubing to the bucket is partially clogged. But, it is resolvable. Here's what you'll need to do.

Turn the unit OFF & unplug it from the wall. Remove the bucket and at the inside top of the bucket holder, you will see a hole or a tube that drains water into the bucket.

Using an 18" long plastic Zip Tie or something similar (NO wire coat hangers, though) that is appropriately sized to fit in the drain hole or tube. Carefully insert the Zip Tie and work it in, until you reach a bend in the tubing. You will need to gingerly work it past this bend, until it either bottoms out or your run out of usable Zip Tie. Then, slowly remove the Zip Tie while rotating (twisting) it. This will dislodge any clogs. Once you start nearing the end of the inserted tip, be prepared for some water to follow.

After completing the above, reinstall the bucket, making sure that it fits "squarely" from top to bottom into the bucket holder. The bottom should not tilt down at all. Plug the unit in, and turn ON the Master ON/OFF Switch. Lower the humidity extraction level to 32 -35%. If you don't have an LED screen on your control panel, set the manual control to Maximum.

One other thing that you want to do on a regular basis. That's remove and clean the air intake filter, if necessary. Be sure to turn the unit OFF and unplug it, before removing the filter.

Hope this helps you to troubleshoot and solve the problem. Please let me know. Thanks.

I have the 25 pint unit and it leaks underneath the bucket. Water does get pulled into the bucket but when running water leaks out at the bottom and puddles on the floor. The bucket has been checked for...

If the unit is leaking under the bucket and you haven't been able to find a crack or hole in the bucket. The bucket may not be properly inserted in to the dehumidifier. Remove the bucket, empty it and reinsert it into the unit making sure that it fits in squarely (Top to Bottom).

If the above doesn't correct the problem, the drain tube to the bucket may be partially clogged. To check this, you will need an 18" long, plastic Zip Tie or something similar. But NO wire coat hangers. Turn the Master ON/OFF Switch to OFF and unplug the unit. Remove the bucket and you will see a drain hole or tube at the top of bucket cavity. Carefully insert the Zip Tie and continue to push it in unitl you reach the bend in the tubing. You will need to gingerly work it past this bend, until it either bottoms out or you run out of usable Zip Tie. Now, slowly remove the Zip Tie while rotating (twisting) it. As you reach the end of the Zip Tie be prepared for some water to follow.

Hope this helps you troubleshoot and solve the problem. Please let me know. Thanks.

I have just had my second dehumidifier stop working. Both have been used exclusively in my basement from spring through fall. The first one (kenmore) lasted 5 years, and the second one (LG) lasted 2 years....

Brad, you have really hit on something. In fact, it's more common than the manufacturers want the consumers to know. Actually, the corrosion starts after the unit is not used for several months and then put back into service. Is there something that can be done, on the consumers part to help prevent this? Perhaps, but, it would require routine maintenance, which most consumers don't even think about, until they ave a problem. Like cleaning the air intake filter regularly, checking the drain hole or tube for clogs and when not in use, storing the unit in a dry environment. As far as preventing the corrosion is concerned ... Doing what you did, to expose the front coils and in addition, wiping the down the coils and spraying a light coat of WD40 on them, may slow the corrosion process.

The bottom line is this. Until the manufacturers switch from aluminum coils to copper coils, the problem will always be there. But, the downside to the consumer will be, copper is more expensive than aluminum and therefor, the cost of the dehumidifier will be higher.

Again, good job, Brad! Your theory was well thought out.

Dehumidifier ices up on back - Why?

If this is dripping and making a water problem yep it needs some insulation on it as long as everything else is working OK. If it seems short of capacity and or not dehumidifying the problem may be short of refrigerant. You don't mention any of this so I'm thinking its OK and not a problem just how it works in your application.

Hope this helps Please rate me accordingly and good luck.

Mine did this last year. I took the housing off of the left side and found a clear plastic tube had popped off the fitting, I put it back on and it worked fine. The tube was toward the lower front of the unit.

Fault Codes

This is more of a tip since I have not actually fixed anything yet. As a test, remove the upper front cover where the buttons and displays are. (2 screws on the bottom then pull off a the plastic snaps) Inside the case on the far left, there is a piece of crimped copper tubing, open on the top end, welded to the refrigerant line, with a black sleeve covering 2 wires out the bottom end. This is a thermistor. I CAREFULLY applied heat with a butane lighter (the mini torch kind, not the "candle flame" kind), taking care not to burn anything. I applied ONLY enough to make it slightly warm to the touch. Do not think of melting anything, as this is not the purpose. Applying too much heat could damage the thermistor. With the bucket in place, the unit started right up. After I did this, it failed again in a few minutes, so I heated it again, and thus verifying it as the source. I have done it a third time, never getting it much over room temperature, and it is still running after almost an hour after doing nothing else. Since this temperature sensing is an analog function to the microcontroller that runs everything, the fault could be any bad connection or solder joint along the way from this thermister to the controller. But is sure appears something in thermistor. I hope my description is complete and clear. Good luck.
