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!

(your welcome).

no really..."de nada". :"don't touch your moustache" "Doye toche moche"(?), "prego".

I called Delonghi on this issue and they said it was a problem with part NE1509 known as "sensor". I sent for the part though from a dealer and it did not fix the issue.

    I'll update this commen. It only worked for about 3 hours. Tried it again, nothing. So, off to the dump it goes. The dehumidifier did work well for 4 years (maybe 5) which seems to be longer than most these days.

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

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.

E3 code...what to do? on dehumidifier


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.

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.

Dehumidier Delonghi DH400P not removing any water from the air


Only thing I can tell you to do is to make sure that the evaporator in the back is ice and cold. If the evaporator is not cold the unit will never remove moisture from the air. And if that is the case you have a sealed system problem. The unit may have a leak so there is no gas in it. The compressor may not be working or the humidstat my not be working properly. So check those thigs out or if its under warrenty call for service.
