Leak my dehumidifier has a pump and the hose connection seems fine. there is a leak coming out of the bottom that i can't figure out. i have the pump on. there is no water in the big bucket however there is a tiny bucket in the large one that has water in it. the leak is not coming from the side with the bucket.

Hey friend, thanks for your post!

It sounds like your dehumidifier needs to be professionally cleaned. What could be causing the problem is a buildup on the inside of your dehumidifier where the water drains out and it is causing the water to not drain properly. Additionally, I would check to verify that the drain hole is tightly secured with the plug. I know you stated that the bucket is not leaking but have you removed it to verify? Please comment back if further assist is needed. -Matt

The classic model drains thru the clear hose using gravity. The drip pan in that unit is about 1/2 way up in the cabinet. Make sure the drain hose exits the unit and runs flat or downhill. If the drain hose is coiled vertically or run up hill causing water to trap within the hose it can cause water to back up in the dehumidifier drip pan and overflow causing your problem. If your drain is higher than the base of the dehumidifier, you can raise the dehumidifier or you can purchase a condensate pump kit that will allow the drain water to be pumped up to 15 feet above the dehumidifier.

The drain hose may have become disconnected from the drip pan as well. To check, turn off the humidistat to stop the dehumidifier from running. Next disconnect the cord from the power supply. Remove the six screws holding the cabinet side (with the label) from the cabinet and remove the cabinet side. The drain hose connects to a nipple on the bottom of the drip pan.

First, the hose should not exceed 5 feet in length. There is no pump in that model dehumidifier. It relies totally on gravity to drain through the hose.

If all of the above is as stated above, I suspect that hose or the tubing inside the hose connecting is clogged. Which forces the water into the bucket rather than the hose.

To remove the clog in the unit, you will need an 18" long plastic Zip Tie or something similar, that is appropriately sized to fit into the hose connection/drain hole. NO wire coat hangers though.

Carefully feed the Zip Tie in to the hose connection. About 6" in the tubing will bend. You need to gingerly work the Zip Tie past this bend, until the Zip Tie bottoms out or you run out of Zip Tie to work with. The slowly remove the Zip Tie while rotating it. This will breakup clog. As you near the end of the Zip Tie coming out, be prepared for some water to follow. DO NOT perform any of this while the unit is plugged in to the wall outlet.

Hope this helped you solve the problem, Robert. Please let me know. Thanks.

Your pump hose may be damaged or the adapter that connects the small hose to the pump may be loose. The pump itself may be damaged as well. Unfortunately this means that the unit must be partially disassembled in order to access the pump and associated tubing. The pump is located on the bottom of the dehumidifier next to the fan.

You can call Therma-stor service at 1-800-533-7533 for specific advice on your dehumidifier.

If you look above the tubing, there's a little gray nub/cone thing. Slide the tube onto that and it should fix the problem. If you're trying to use the pump instead of the collection bucket, there are good directions in the manual.

I think that I am having the same problem, but I'm not sure that this tube needs to be plugging into anything. However, my humidifier seems to be draining out of this tube rather than from the tray into the bucket.

Find where the leak is coming from. Is it coming from the connection where the tube goes into the dehumidifier or where the garden hose screws on? If it is where the garden hose screws on make sure it is screwed on all the way. If it is you may just need to replace the rubber washer in the garden hose.

Hey ya! To fix this u need to block that hose connection under the Dehumidifier. This will then re direct the flow to the Bucket collection mode. I have the same problem and resolved it this way after pullng mine apart. It looks like by default that hose connection at the bottom should have a plug/cap on it and after turning on ur dehumidifier this fills up then once full it starts to over flow into the bucket... Seems a strange design but thats how they have done it.

Hope this helps others.

I was under the impression that the drain hose connected to the bucket with a screw on connection such as with a garden type hose.

let me know if you still have this
