After running for awhile the pump light starts blinking and the drain tube is not bent ?

For the others who follow

I have the same model, same problem on a 2 year old purchase made in 2014. This unit has a pump (and a hose) to drain the condensate.

The pump light started blinking about a week ago, turning cycling power worked for a while, until pumping stopped altogether.

After investigating:
-the hoses are not blocked but there was some algal growth in the tray which I cleaned
-the pump no longer pumps.
-my favorite parts suppliers and other on-line sources have no record of the model/parts etc.
-Called "whirlpool" consumer line in manual
-Whirlpool has been purchased by Garrison and that company has no parts for this discontinued model but did provide a phone number for the pump 800-799-0991. Unfortunately the cost of this small solenoid pump is $74.

I will drain the condensate via gravity to a floor drain as I don't see spending that much for something that broke so quickly and appeared poorly made..

Clogged sensor with a mud. Clean it

The hose or the hose connection and internal tubing may be clogged. To solve this problem, turn the unit OFF & unplug it.

The hose is easy to check, by disconnecting it and blowing thru it. If it checks out OK, then the clog is in the hose connection on the unit or it's internal tubing.

Using an appropriately sized, 18" long, plastic Zip Tie, carefully insert the tip of Zip Tie into the hole and tubing. Continue to push it in until you reach a bend in the tubing. You will need to gingerly work the Zip Tie past this bend, until it either bottoms out or you run out of usable Zip Tie. Then slowly pull the Zip Tie back out while rotating (twisting) it. This will breakup any clogs. As you reach the inserted end of the Zip Tie, be prepared, as some water may follow. Reconnect the hose, plug the unit in and turn the Master ON/OFF Switch to ON. Set the humidity extraction level to 35% or Maximum if you have a manually controlled unit. Allow the unit to run, while you monitor the hose for water flow.

NOTE: If you don't have a Zip Tie, you may use something similar ( i.e.a long pipe cleaner), but NO wire coat hangers.

Think the problem is with a clogged tube running to the drain, rather than a faulty pump.

To test this theory, first turn the unit OFF & unplug it. Using an 18" long, appropriately sized, plastic Zip Tie. Carefully insert it into the drain hole tubing and continue to push it in unitil you reach a bend in the tubing. Gingerly work it past this bend until the Zip Tie bottoms out or your run out of usable Zip Tie. Then slowly pull it back out while rotating (twisting) it. This will help break up any clogs. As you reach the tip of the Zip Tie, be prepared as some water may follow. Plug the unit back in and turn the unit ON. Set the control to Pump Mode and monitor the drain for water flow.

I hope this helped you and thanks for choosing FixYa.

The drain tube of hole inside the unit may be clogged. Unplug the unit and remove the water container. With a flashlight look up and into the unit to locate the tube or drain hole. Using a 12' long Zip Tie, carefully run the Zip Tie up into the tube or hole, as far as you can. Gently turn it and with draw the Zip Tie slowly. This should remove any clogs.

Hope this helps to solve your problem.

It may be gathering water, but the tubing to the drain bucket may be clogged. Turn the unit off, unplug it and remove the drain bucket. With a flashlight, look up into the interior of the cabinet and you will see a small tube or water outlet. Using a flexible Zip Tie (at least 6' long), carefully insert it into the drain tubing or hole. And carefully move it back and forth. This should remove any clogs.

Also, check the filter on the unit, as it to may need cleaning, too.

If you've had this unit for a number of years and the above trouble shooting doesn't solve the problem, it may be time to replace the unit.

Also, if you continually have "a lot of water" in your basement, you might want to install a sump pump. In the long run, it's a better solution and will pay for itself in a couple of years.

If the unit is titled forward at all, the "full bucket" "trip switch" will not trigger off as it should. Be sure the unit is on a flat, level surface, or leaning backward slightly--this also aids drainage through the drain tube, if that's your set-up.

same thing happend to me. I wasnt sure if it was the settings or me. I unplugged it for awhile, read thru the instructions turned it back on setting it according to the instructions and it began to work again. Not sure if it had to do with the unit being off for awhile or I entered the correct settings. Im just happy it began to run again

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.
