Delonghi Dehumidifier DE500P - Code E3

Hi Speedy,
I'm having the code E3 on my dehumidifier. I have called customer service and they adviced me to ship the unit to a service center which is about more than 3 hours drive from my house and the shipping cost was more than $100. The service center would not tell me what the code E3 means so I figured if I can just fix it myself.
Can you please tell me where you order the part and the part id so that I can just order and have the unit working agains. Thanks

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!

    Am I going to get the same wrong part first? How do I get away from this?

  • Susan Hutt Aug 11, 2011

    You may as well take your help ad out speedywheel, as I called today to get the part and they cannot do it any more, by law. I feel so bad, here I have a beautiful machine that is too heavy for me to even take to the dump - I can just see it now, mile after mile of Delohghi dehumidifiers that have parts that someone may be able to use. Too bad!!! Personally, I'm sick about it.

EC appears and it doesn't draw water

I contacted CE North America customer service regarding this issue for same unit. They suggested disconnecting for 10 minutes, then reconnecting, turning unit on, and changing settings and run fan on HIGH or TURBO until the EC code goes away. This didn't help with my unit. If this doesn't work, there is no repair provided. Customer Service recommended returning unit to purchase location if under warranty (1 year), however a copy of the original purchase receipt is required. Suggest a call to Customer Service Center at 866-915-1212.

I have Delonghi DE500P dehumidifier was running but doesn't pump water. how can i fix it.


First, make sure the humidistat isn't set too high by adjusting it to the lowest humidity setting and running it again. Next, test the dehumidifier by placing it in a closed bathroom with a hot shower running. If you don't see water collecting in the unit after several minutes, turn the unit off and clean all dehumidifier filters and coils. If, after adjusting the settings and cleaning the unit, you still don't see water collecting, you may have a refrigeration issue. This situation will have to be addressed by a qualified technician.

Good luck

Unit wont poker on.

Here is a bit of info:

No one is authorized to service the unit. From thier FAQ's::

Does the Bionaire® brand have walk-in repair service centers?
No service center is authorized to handle claims on our bealf. Please contact our Consumer Services department at 1-800-253-2764 to speak with a trained specialist and receive appropriate shipping information.

In other words.... BIONAIRE is the sole distributor and servicing point for this unit.

Contact data

3. Should your dehumidifier require service, please call
1-800-253-2764 in North America for further assistance.
4. ? If you have any other questions or comments,
feel free to write to us or visit our website
The Holmes Group, Inc.
Consumer Service Department
13052 Jurupa Avenue
Fontana, CA 9233

There are probably parts you could replace but without any service manual data or replacement parts data it really is difficult for us to help you.

Your unit has
1. a Humidistat
2. a Fan
3. a Compressor and all of its' start run components consisting of a start relay thermal overload and a run capacitor.
Obviously there is a problem with one of those components. It will be a matter of isolating which one and then going to your local appliance parts center (WITH defective part in hand) to purchase the parts. (IF they have them...)

Thanks for using FixYa.

What does P1 mean on display?

Danby's Consumer Help Line (1-800-263-2629) is always busy. So, I called their General number: 419-425-8627. The receptionist transferred my call to their Service dept. My call was answered in 2 minutes.

The Service Rep. described the following code for my dehumidifier model (DDR657EE):
P1 = Defrosting: the unit will go into Defrost mode periodically to ensure that the parts are working at the right operating temperature. It should be in Defrost (P1) mode for only a brief period of time. If the unit is in Defrost (P1) mode continuously for a couple of hours (or more), then you should call Danby Service for further assistance.

He had no documentation of a P2 code for my model.

He also described other General Codes (applicable to most Dehumidifier/Humidifier models):
E1 = Not enough water
E2 = Not draining
E3 = Water temperature too cool
E4 = Overflow Switch activated
E6 / E7 = Problem with Temperature Sensor

I hope that helps.
