Question about Hartell Condensate Pump

Open Question

My Hartell condensation pump makes a loud, thumping noise when it is not pumping water out to the sink. The noise speeds up before eventually stopping, and then a few seconds later the pump turns on. It appears that the noise is coming from the check valve, and as the pump is drawing water from the humidifier it is also sucking air back from the tubing that runs to the sink. The HVAC company has said this is what is happening and I believe they are correct. When I cover the end of the tubing, within a few seconds the noise stops and when I pull my finger from the tubing I can feel a small vacuum has been created. I actually changed the check valve once and it didn't make a difference. The HVAC company has suggested that I pay them to install a second check valve along the line to stop the air intake, but I really don't want to pay them more money for this after I already paid a few hundred dollars to have this installed. Any thoughts?

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)

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..

Condensate pump buzzes but does not remove water. have blown out discharge hose and clean check valve with changing symptons. Should I give up and put it on a box and buy a separate condensate pump or...

Edwin, according to the Owner's Manual, when this happens the drain hose is not connected properly. Turn the unit OFF and unplug it, then disconnect the hose and reconnect it. Plug the unit back in, Turn the Master ON/OFF Switch to ON and press the pump button. If the hose is connected properly, the pump should tunr on and pump the water out.

To help you further, I have included a link to the Owner's Manual for a Delonghi model like yours. Once you go to that page, click on the Acrobat Reader Icon and download the Owner's Manual. You may print it is you like.

Hope this helped you. Please let me know. Thanks.

Attached a pump to drain collected water. The

the water should still collect into the tank. the dehumidifier had a float switch that shut the unit off when the tank is full. In turn it should have a second switch, probably a float switch that turns the pump on and off so that the pump doesnt continue to run when there is no moisture in the tank

I wish to purchase DDR606 dehumidifier. Will need to place a pump into bucket to send water up basement wall and out thru window. Will this work with this model? Thanx!

This will work for all models. You just need to get a condensate pump. Hook drain from dehumidifier to the condensate pump. the dehumidifier will need to be higher than the pump so it can drain.

Dehumidifiers and how they work
Heat pump dehumidifiers

Dehumidifiers use a heat pump (similar to an air conditioner's heat pump) or chemical adsorbents to remove moisture from the air without cooling the air.

A heat pump dehumidifier uses a fan to draw indoor air over a heat exchange coil. The coil is almost freezing. The water in the air condenses on the coil and is drained. A second heat exchange coil reheats the air, which the dehumidifier exhausts into the room.

A heat pump dehumidifier dumps heat lost from the compressor and fan motors into the air. It returns to the indoor air the heat generated by the dehumidifier turning water vapour to liquid. I got this off the internet

Vertical draining

Water only runs down hill. To accomplish your task you would need a small condensate pump to get the vertical lift to transfer to your sump. as an example ",,CLI1_DIV32_ETI3740,00.html"
