I have a Blyss WDH316DC dehumidifier with E3 in display. What does this mean?


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

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.

Unfortunately, Delongi doesn't list an Owner's/Operational Manual for your model dehumidifier. However, you can contact their Customer Support Dept at 800-322-3848. They can provide you with the Error Code solution, as well as email you an Owners Manual. Be sure you have the correct model number for your unit, before calling.

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!

Lost owners guide to delonghi dehumidifier de400p showing code of e3


I am searching for a resolution to the E3 code (same init) and happened upon this request. The manual can be downloaded from DeLonghi.com but that advises you to call the service center.

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
