SOURCE: Drain problem

I have the same problem and after talking (mostly waiting) with Fedders repair, I have been told how to solve the problem. Plug up the drain hole on the right side (the one not connected to the drain hose). The drain hole extends down about 5mm, outside measures 10mm and interior measures 7mm. They do come with a drain hold cover. Not a replaceable part with a number. Off to the hardware store.

SOURCE: Problem with draining water through hose

I raised mine up on a platform about 6 inches, and now mine works fine. Don't know why this is necessary, but atleast it works now.

SOURCE: Pump not pumping

It's not a one way valve, it's a water strainer. It has a barrel with a fitting on each end, the upper leads into the barrel, the lower has a strainer tube attached. When it's plugging up, it seems like a one-way valve because when you try to force water into the top, it pushes the lint and junk against the strainer screen, blocking it. When you try to force water in from the bottom, the water pushes the lint away from the screen, allowing a reduced flow. Some have an arrow; it's to indicate flow direction to keep the lint on the outside of the screen; the inside, being mush smaller than the barrel, would plug up much sooner. Before you replace the strainer, clean the lint & stuff out of the small pump reservoir (above the pump). If you don't, the strainer will plug up quickly again, if it can even get water to it.

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.

Is there a special code to direct water to pump, dump bucket or drain


That would be the "Pump" button on the control panel. When you press it, your dehumidifier display should indicate "PUMP", and the unit should start pumping water out that little port at the center rear of the dehumidifier.

Alternatively, you could stand the dehumidifier on a counter and direct your waste water out the larger hose connection into a sink.

I personally carry it (more than five gallons per day) upstairs to the laundry, because it's distilled water - the softest water you can get. Works GREAT in the washing machine. 8) 8) 8)

Pump not working


If you've checked power to the pump and it isn't working, it needs replacing, unless it's blocked with slimy deposits. Try a vacuum cleaner on the drain hose outlet

Dehumidifier isn't not removing humidity. Fan and lights are working, but the water container remains empty. It is not pulling water from air. I think that the heating element may not be working.

My dehumidifier keeps beeping??????


The water tank is either full or not positioned correctly. Empty the tank and/or make sure it is positioned correctly (should fit perfectly and not bump out from rest of unit).

If you have it connected to the drain directly, your tank may still be filling up unless you have the PUMP button pressed (and PUMP is showing in the LED screen).

Good luck and please rate me.

Hose not draining, bucket only fills


The easiest way to unstop the hose is to blow air through the end enough to clear the clumped up dust at the other end using air compressor or air pump.

DeLonghi dehumidifier hose by drain tray leaking


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.

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

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

Leak


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.
