20 Most Recent DeLonghi DD50P Dehumidifier Questions & Answers


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)

The reason this happened may be two fold. Either the hose is clogged or the length of hose is to long and then has to go up hill into the slop sink. The owner's Manual says the pump is rated for an 8 foot lift. However, what I have discovered is that rating, does not take friction loss in to account.

Try moving the unit closer to the sink and shorten the hose about a foot or two. Actually, a floor drain would be perfect, if you have one in your basement.

You really answered your own question. The pump in the dehumidifier only has so much water lift capacity. By trying to run it up and out, you have exceeded the maximum lift capacity. Using a floor drain or even a bathtub drain in the basement will probably work, as long as the hose is not to long.*
However, if you can use a floor drain, there's no need to use the pump function. You can use the continuous drain on the back of the unit. using the drain hose provided for that application.

*The 13 ft lift capacity noted in the Owner's Manual includes whatever length of hose you're using to get to the window. As there is some friction loss involved. But, they fail to point that out.

Hope this helps you and thanks for choosing FixYa.
