Delonghi 500P has stopped working completely (no fan, no controls) and displays error code E-3. Delonghi tech says this is a sensor failure but not which one. I have tried removing and cleaning the sensor clipped on the right condensation coils (on 4 pin connector), but no luck. Any other suggestions. I also get E3 error and was told to ship the product to a dealer in CT.
It will cost more than the unit is worth to ship and repair this, I am looking for the quick fix or its the scrap heap!

Re: Error Code E-3
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
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...)
I don't know if this will help i have a delonghi portable ac and the e3 means not enough voltage to run properly. but it was doing the same thing as yours. i plugged it in where i knew there was good enough voltage and it works fine now

id be inclined to think that for some reason the pump is taking too long to pump tank out (or it thinks it is ) this would cause the fault you describe and the safety control shuts pump off for fear of a problem
Good Morning friend, thank you for your inquiry!
I see that you are having trouble with your Frigidaire dehumidifier displaying an error code of "F2". Typically, an "F2" error code stands for a miscommunication error. This could be a possible problem with a sensor or control panel. I would suggest performing a reset and that can be completed by disconnecting the power from your dehumidifier for roughly ten minutes. If you are still under warranty I would recommend contacting your manufacturer to see if any additional assistance can be provided. Hopefully this is helpful. -Matt
You can try cleaning the humidity sensor, which is on a circuit board housed in a nylon clip attached to the cooling coils. The sensor is in a plastic clip, which can be opened up and cleaned. Some report success. Didn't work for me.
I ended up rewiring the unit so that a 5v control line from the lower relay board goes through the SPDT bucket full switch, turning on the control board when full (so it beeps), but otherwise enabling the compressor and fan. The fan and compressor are controlled by relays, which are driven by a ULN2003AN relay driver. I fed the empty side of the full bucket switch back into the relay driver to turn on the compress and the fan on high. I plan to put a dehumidistat in series with this control line; now it just runs till the bucket is full. A Broan DH100W dehumidistat is 20 bucks. Could also put in a rotary switch to control the fan speed, but for me high is enough.
I think this machine is made by Goldstar for Kenmore and Delonghi. Stuff is just made to break and through away these days, which is a shame.
If you have the fan icon selected, it is supposed to run continuously. If you use the mode button (not the fan button) to change to relative humidity (the water drop icon), the fan should only run with the dehumidifier.
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.
