Question about DeLonghi DH40P Dehumidifier

Open Question

Working The unit works OK...every couple of days I have to drain the holding tank. However, when I go to empty it, there is ice formed in the housing that prevents me from removing the tank, so I have to wait for it to melt. Also, the pump works, but is that the only way to use this unit without the holding tank? It does not seem to drain from the hose outlet unless the pump is on. Is there a passive way to use the hose (non-tank) method?

Does not shut off when tank full, water leaks all over the floor if I don't watch it constantly


Sounds like the float valve inside tank may be stuck in closed position. Calcium buildup is very common. Good luck Juliana. Unplug and empty tank of any water and look for the float valve it should be near top of tank. Use a small bucket and mix vinegar and water and brush. Scrub that valve. Clean it up

I own a Whirlpool Dehumidifer Model Number AD 70USS1. I have a drain hose connected to the unit, however, recently the unit's internal collection bucket fills with water to the point that the...


superstee - You're having to empty it because either the drain hose you have connected to the unit is clogged or the drain hole a the hose connection is clogged. Therefor, the water is drained into the tank, rather than the drain hose. Also, the drain hose would not be any longer than 5' and must drain down, as the dehumidifier does not have a pump. It relies totally on gravity.

Remove the hose and check it for clogs. If clear check the drain hose connection, using an 18" long appropriately sized Zip Tie. Carefully insert the Zip Tie and continue to push it in until you reach the bend in the tubing. Gingerly work past this bend, until the Zip Tie bottoms out or you run out of usable Zip Tie. The while slowly pulling it out, rotate the Zip Tie. This will dislodge the clog. As you reach the end of the Zip Tie removal, be prepared for some water to follow. CAUTION: BEFORE DOING ANY OF THE ABOVE TURN THE MASTER ON/OFF SWITCH TO OFF AND UNPLUG THE UNIT.

The above should solve the problem for you. Please let me know. Thanks.

Dehumidifer "froze" Turned unit off removed ice and left for a couple of months. Turned unit on motor works but does not remove moisture.


timer is not working, or thermocouple is defective.
unit must cycle forward-reverse to remove ice, thisis how it works, by melting the ice that forms.

Does not generate water. The fan keeps on running. Forms ice on coils


If the room temperature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

My dehumidifier runs, but no water is collecting. Humidity in the house is about 57%. The unit is only 3 months old.

Ge dehumidifier ahh50lmg1 unit does not automatically turn off when full


There is something holding your tank in the "empty" position. Look into the tank bay carefully for debris or packing that may be obstructing the auto shut off feature.

Can you drain your tank to a sewer or sump?

My Goldstar dehumidifier is still draining water, but is forming snow/ice out the top of it. I've had a couple of years and has worked beautifully. Any suggestions?


Your unit has a sealed system leak. The sealed system is warrantied for five years. Find your receipt and call an authorized LG dealer to initiate an exchange.

Will not turn on


Boys and girls, I hate to tell you this -- but those units are DEAD. I had the same problems as being discussed here (not turning on, electronic chirp, bucket full signals), but with one other important feature -- the unit became so hot that I couldn't touch the top. At first it sounded and smelled like the fan was jammed, and later it sounded like the compressor wasn't working.

Anyway, after two weeks of dealing with LG (1-800-243-0000, and be prepared to call back several times as they have a phone problem), they have finally decided to refund me the money on my unit. Give them a call and speak to them. Also, as my unit was intermittently working, I would recommend that you unplug your malfunctioning unit if you are having these problems. A dead dehumidifier is one thing, a house fire is quite another thing.
