20 Most Recent DeLonghi DE500 Dehumidifier Questions & Answers


I think this means your pump is not working, and therefore the tank is full. The pump could just be switched off, could have failed, or could be clogged. See the other messages regarding this model, for an excellent description of how to clean out a clogged pump.

I agree with Mike Kolbay's earlier very complete answer. The water intake to the pump is quite narrow, and clogs easily with accumulated lint and bacterial muck. While the covers are off the machine, thoroughly clean the drip tray and all the water passages. A piece of crud the size of your smallest fingernail can cause water to overflow onto the floor, rather than going into the tank.

I have the same problem. Very annoying. My suggestion is to go to your nearest dealer and throw the unit through their front window.

If it is showing E1, E2 or E3, contact the service center. The manual can be gotten at:

Again!!!! Unplug machine X 15 minutes. Then fill with water. Then plug back in! If still lit, you have a water scale (mineral build up) issue that needs cleaning according to owners manual

I got mine fixed tonight! It was not that easy but can be done.
After my last post, I called the customer service of DeLonghi. The agent can only refer me to the authorized repair shops but she does not know what “E3” meant. There is no shop in NJ where I live, and the closest one is in CT! One of the two shops there knows right away the E3 is the fault of a condenser sensor. He mailed me the part ($25) and I took the covers off (be very careful to record where the screws are from ---- they are not all the same size/shape, and also there are two small tabs on the top holding two cover pieces together, so don’t force it to open or you will break it). There is only one part looks like the same as the replacement part I newly obtained and it has a metal clip attached on the copper coils. Carefully replace the sensor on the coil as you find previously and plug the other end to the control board. It sounds lengthy but once you open the cover it will all become clear to you. Be patient and this can be done. Very glad to see/hear it is working now again!

p.s., the store first mailed me the wrong part (on the plug-in end it has two ridges rather than one) so I have to call them again to explain and they mailed me a different one with a single ridge. Apparently there are two types (old and new model) for this model.

these humidifiers are total junk. The sensors are cheap and get stuck or broken so easily. for your problem tho, you can either find the sensor by taking off the cover and use your hands to break free any stuff causing it to get stuck or you can drill a hole in the water tank and insert some fish tank tubing and let the water drain out as it collects.

Hi Thomast5263,
I live in NJ and the nearest center is in CT. So you can imagine that I am not gonna to ship my unit! :-)
The one I got is from Hartford, CT Utility Electric Service: 860-246-7271; talk to Dana and he is very helpful. They charged me $25 and shipped me the part and it now works fine.
When I talked to Dana he sounded pretty sure it was the condensor sensor. Simply call Dana and tell him that you have an "E3" code. I do NOT know the part number or ID.
Don't open the unit until you get the new part ---- it will help you to identify the part to be replaced. After you get the part, make sure you mark down all the screws (they are not the same! so pay attention which one is where). There are two tabs on the top so be careful when get them separate apart ---- don't force it or you might break it. The sensor itself is attached/stuck in between the copper coils under a black cover. Plug another end to the control board and you are done. Apparently there are two kinds of plug-in end ---- the first part Dana shipped to me did not match the old part so he has to send me another one which worked.
The whole procedure is not that difficult, but when you are doing this the first time you just need to be patient to locate all the screws and sparate the covers. From my experience you do need to take all covers off, otherwise you can not see the part and the wire.
Good luck to you and let me know the good news!

Condensation sensor was tripped...needs to be dried/cleaned/repaired (on lint screen side remove plastic panel. The sensor is clipped to radiator fins.

Be Safe or don't do it....

On the side with the lint screen, remove the five screws holding the top panel in place. The sensor that needs to be checked in mounted on the radiator fins. Remove the sensor and 4 pin connector. With a pin, remove the loose fitting housing the "sensor"...a circuit board that "shorts" with condensation...check corrosion and look for component damage on the oft chance the circuit board was damaged by some inappropriate poking or mechanical failure. Reassemble and replace sensor...

For a short life span...or out of warranty and only at your risk (IF have significant other or kids or pets or human DNA... don't do this...) .. guide wire through screen notch and attach to outer screen. Build fortress around exposed sensor and talk to insurance agent for a special rider...seriously be careful.



Did you? Clean screen and GENTLY clean fins of lint, etc....(vacuum's brush head should do the trick...)

Taking all appropriate safety precautions.

...


Here's the 100,000 (yen) tip....with humidifier unplugged, hold down the power button (green button in lower center) and plug in the appliance.

Watch the LCD screen as it conducts a self test...and wha...lah!.

There are 4 basic, yet solvable reasons for what you have described.

1. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

2. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

3. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

4. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder
level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

I hope this helps you troubleshoot & solve the problem. Thanks for choosing FixYa.
