Question about DeLonghi De'Longhi Energy Star174; Approved 40 Pint Dehumidifier - DE400P Dehumidifier

Open Question

The pump is no longer working on my DP400 40 Pint dehumidifier. What should I do?

For 2 blissful months my DeLonghi DP400 40-Pint dehumidifier faithfully pumped the water into the drain.  Then about 2 weeks ago, I started to hear this beeping sound.  I discovered that the bucket was full, so I emptied it.  In 2days  it was full and beeping again.  I've searched high and low and cannot locate my owner's manual to determine how to get the pump working again.  I've searched on-line for a manual without success.  Can anyone help me figure out how to get the pump working and where to locate a manual on-line, so that I can return to that blissful state again?

Thank you!

    My pump worked fine for about 2 years then stopped and makes a very loud grinding noise if I try to turn it on. I also cannot find my manual. Anyone have any suggestions?

    I have a DeLonghi Dehumidifer CF80M. I was putting the tray back in after emptying and it got stuck! When I tried to put it back in again it was with some difficulty. It seems a small silver piece may be bent? Although it's working i.e. has power - there's no longer any water collecting.

    Can you advise?

SOURCE: water bucket

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

It's for when you dump the bucket. You put the cup in to catch the drips while you're dumping it.

SOURCE: 50 pint dehumidifier has drain hose connected but

safety switch is turning off the dehumidifier....you need to drain out the bucket more often....or put the drain hose into an actual drain....ive seen some people run a small plastic hose from the dehumidifier to the sump pump hole in their basement.

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)

Why is my Kenmore Energy Star 50 pint model 251-50501012 dehumidifier leaking water after I disconnected the drain hose


If you reconnect the drain hose, make sure that it lays flat from the dehumidifier and into the sump pump hole. I did that and it solved my problem of water leaking onto the floor.

Need for a home dehumidifier for a 120 square meters space


normall you will need one pint of water for each 1,000 cubic feed of space in your . . example. 2,000 square foot with 8 foot ceiling would contain some 16,000 cubic feet. = 16 pint per day capcity to dehumidify the area.

God bless you

Kenmore 407 50 pint dehumidifier won't drain through hose


Did you punch out (or cut) the plug that the hose connects to? If not, its blocking the water from draining to the hose.

Also, make sure the unit is higher than the drain and that the hose is not kinked or clogged.

Please rate 4 stars if this is helpful. Thanks and good luck!

What should I set it at


If there is actual water in the basement, any setting will probably cause the unit to run. I would suggest setting it around 60%, and turn it up as you feel necessary. Hope this helps
