Error code E3 on delonghi dehumidifier DH400P

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.

T Decker - Thanks so much. I tried it and now our dehumidifier is working.
