How do I fix leaking dehumidifier?

You need a full strip down, clean and look for holes or failed sealant.

I am also an air conditioning tech, with same problem and same soleus dehumidifier problem. you must remove the plug and install the drain line hose adapter. Hose must lay flat and have no "hills" for water to drain. With this done pull your drain pan out and set aside. look under right side facing the dehumidifier and you will see a small spout. Has a lip like a little tea pot. Plug that spout. I used a foam ear plug used in work shops. Now give the front of dehumidifier a slight rise on front wheels about the thickness of a pies of cardboard 1/8 to 3/16 of an inch. Now put drain pan back in an start up. The problem is the drain pan was made with very little differance in pitch between the the hose drain and the bucket drain. Remember to check your drain hose periodically and the air filter also. Good luck

The drain tube that drains the water into the bucket is clogged and needs to be cleared.

To do this, you will need at least an 18" long plastic Zip Tie or something similar. (But, NO wire coat hangers) that will fit into the drain tube or hole. Carefully work the Zip Tie into the hole or tube and gently push it forward. You will reach a bend in the tubing, but you will have to gingerly work past this bend. Once the Zip Tie bottoms out or you run out of Zip Tie. slowly pull it back out while rotating it. This will help breakup the clog. Once you start reaching the end of the inserted Zip Tie, be prepared for some water to follow.

The above procedure should solve the problem. Please let me know. Thanks.

Sorry, but your Model # doesn't match any Whirlpool Appliance in my data base. However, another company may have bought the rights to use the Whirlpool name on house brand that they sell. But, lets get to a solution to your immediate problem.

First turn OFF the MASTER ON/OFF Switch and unplug the unit from the wall outlet and allow the unit to completely thaw, before removing and cleaning the air filter. As, I suspect, the filter is dirty and may be clogged. Historically, this is one of the things that can cause a dehumidifier to struggle and not be able to keep up.

After you remove and clean the filter, remove the water collection bucket and look for the drain tube or hole that drains the water into the collection bucket. Using an 18" long plastic Zip Tie, that will fit into the drain hole or tube. Carefully insert the tube into the drain hole. Continue to push it in and you'll reach a bend in the tubing. Carefully push it past this bend, as far as you can. Then, while rotating the Zip Tie, pull it back out slowly. Be prepared for some water to follow. One word of caution - DO NOT use a wire coat hanger to clear the drain tube.

Reassemble everything and you should be good to go. If however, the unit freezes up again, the compressor may be low of refrigerant gas and it will need to be recharged.

Hope this helps you continue to troubleshoot and solve the problem.

First, is the unit level? Tipped a bit to one side or the other, or front to back could be the issue.
Next, is the drain hole clear? locate where the water drip from into the bucket and push a wire up there to ensure it is clear. use something like a garbage bag tie.

Hi,
Did the hose twist or run up and down so that it makes a double trap???

I just fixed the same problem on my DE-500P. The pump filter was blocked and there was a layer of scummy lint-like stuff in the bottom of the pump reservoir (not the main - or overflow tank) also blocking flow down through the filter to the pump. Repair steps are as follows:

1. Remove the overflow water tank and the two side covers (five screws in each). Note that as you go through the removal of all the covers and other procedures, there are two lengths of screws; don't switch them. If you lose track, the rule of thumb is use the short screws for going through a single layer of plastic into metal.

2. Remove the rear cover (take out the screws along the bottom and on the sides). It will still be attached to the front top cover at the top with tab fasteners. Gently pull out the bottom of the cover while depressing the top of it on both sides with your thumbs (about an inch and a half inside the trim ridges) to clear the tabs. Ease the top part of the cover back and remove it (it will have to tilt to one side, don't forget this when putting it back on).

3. Remove the top cover, not forgetting the two screws on top by where the back cover attached (go gently, there's a wiring harness) and turn it to the side. There was enough slack to leave the wires connected; just be careful to not damage them.

4. The filter looks like a small transparent in-line gas filter. Remove the pump filter, leaving the short tube attached to the top of it. I quickly atttached a length of tubing to drain the reservoir into a bucket. I couldn't find a replacement filter, so I filed a slot in the side of the bottom half of it to remove the gunk using the wire from a twist tie (the upper half had some tabs inside that would have been in the way). Afterwards, I wrapped it tightly with stretchy electrical tape and put a wire tie over the tape at the slot to keep the tape from being able to creep loose over time. Don't use a fuel filter, the paper element is too fine (you need a screen) and the paper will fall apart in water.

4. Remove the float and bracket from the pump reservoir. The reservoir screws are not all apparent; there's also a screw way over on the left and one coming in from the right. I used a 12 inch #2 phillips screwdriver with a magnetized tip for most of this. Remove the pump reservoir and clean out the scummy stuff in the bottom and where the tubes attach. When removing the reservoir, you'll have to detach the vent line that goes through the bulkhead to where the big tank was and pull the tab above it down slightly while easing the tank out.

5. Clean out any dirty tubes, paying particular attention to the coupling for the drain hose and the long drain hose itself.

6. Put the reservoir back in and hook up all the tubes and filter. It does make a difference in which direction the filter goes back in. You want the water from the reservoir to go through the filter from the outside of the little screen; that leaves the maximum room for crud build-up before it plugs up the screen again.

7. Depending on your confidence level, at this point you may want to plug in the dehumidfier, put the overflow tank in, turn it on, turn on the pump, and fill the pump reservoir to check for functioning and leaks. If you do this, just remember that the circuits are hot and not all are insulated.

8. If all is OK, unplug the dehumidifier and put the covers back on. Total time was about an hour.

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.

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.

check that the removable bucket did not alter a water guide near the cooling fins
