What does an E3 reading mean? - DeLonghi DDE40E Dehumidifier

E3 is a sensor error and some say cleaning the air intake filter can help. Others say the humidity sensor needs to be replaced.

What E3 Means? This is simply an error code with your dehumidifier please.

It s not clear whether you can attempt to reset your unit or fix it on yoir own. So sorry about this.

It appears yoir unit requires repair by a qualified dehumidifier service technician.

You can exploit the warranty if this is still valid. Simply return to point of purchase with your original receipt

I'll need a make and model number for that.

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.

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.

DE500P does not run and shows error code E3. What part do I need to replace and where can I get it?

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!
