    I am having the same exact error message. E3. There must be some kind of reset for this somewhere.

    IT stopped working with E3 - I am returning it to get a quality product that's dependable

  • speedywheel Sep 29, 2008

    Yep I have the exact same problem ---- E3.

    Found the manual on-line and it asks to contact customer service. From their website I got the number 1-800-322-3848. Will call tomorrow and hopefully it is not serious (but I don't think it will be an easy fix ---- otherwise it would not ask us to call them!)

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.

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!.

Should have a working humidifier!

An E 3 error code comes up and I don't have a manual to determine what the codes mean.


An E3 error code is a Sensor Shutdown Failure. You will need to contact Haier Customer Support for an explanation on which sensor it is and how to solve the problem.

The e3 is displayed and beeps ran only a month or two


The E3 Code, indicates that the air intake filter needs to be removed and cleaned. Be sure the unit is OFF and unplugged before removing the filter. Filter cleaning should be performed at least once every two weeks, as part of Routine Maintenance.

Hope this helped you.

Our delonghi de400p dehumidifier shows an E3 error message. Customer Service says its a sensor but can't tell us what sensor. Any help would be appreciated.


I have a 40 pint and a 50 pint that are very similar. The 40 pint has the e3 error. Experimenting with the 50 pint, I found if I disconnected a particular sensor I got the e3 error. That sensor is a little can with two black wires (smaller than a AAA battery but shaped like that). It is attached to the cooling coils so must be a temperature sensor. This is not the little circuit board sensor mounted in the middle of the radiator in a plastic box/clip thing.

I am now about to see that part to see if I can replace it.

Delonghi Dehumidifier DE500P - Code E3


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!

E3 is flashing on display panel


Calling two service centers, they both indicated that the main circuit board needed replacing. This would need shipping the unit!!, part and then labor. I figured over $120 - not reasonable. I then took the unit apart and followed the wires from the compressor to the back of the unit. This is where the moisture sensor was located - upper left. You'll see this when you take the filter off. Anyway, I cleaned the face of this part with a old toothbrush, used some compressed air to remove any dust. I then followed the wires with the black sleeve that went to what I think is a temperature sensor - also on the left. The wires go to a sensor that is pushed into a copper tube that is part of the cooling tubing. Gently pull this out, wipe it down and re-install. I then plugged the unit in, set the humidity level and it now works. I just put the unit back together and the compressor is turning on and collecting moisture! I will run it a few days and keep checking on it to make sure it doesn't go into the 'E3' Mode. By the way, the repair shops I called really didn't have a clue what the E3 code was. Dennis
