Question about DeLonghi DE500 Dehumidifier
I got mine fixed tonight! It was not that easy but can be done.
After my last post, I called the customer service of DeLonghi. The agent can only refer me to the authorized repair shops but she does not know what “E3” meant. There is no shop in NJ where I live, and the closest one is in CT! One of the two shops there knows right away the E3 is the fault of a condenser sensor. He mailed me the part ($25) and I took the covers off (be very careful to record where the screws are from ---- they are not all the same size/shape, and also there are two small tabs on the top holding two cover pieces together, so don’t force it to open or you will break it). There is only one part looks like the same as the replacement part I newly obtained and it has a metal clip attached on the copper coils. Carefully replace the sensor on the coil as you find previously and plug the other end to the control board. It sounds lengthy but once you open the cover it will all become clear to you. Be patient and this can be done. Very glad to see/hear it is working now again!
p.s., the store first mailed me the wrong part (on the plug-in end it has two ridges rather than one) so I have to call them again to explain and they mailed me a different one with a single ridge. Apparently there are two types (old and new model) for this model.

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!
