Error Code E-3

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!

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.

DeLonghi DD70PE Dehumidifier. Why does pump often stop working and F/P shows an error code until reset?


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

The F2 code is on in the humidity window of my Frigidaire dehumidifier? Not in manual. What does this mean?


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

Den 500p dehumidifier fan works but compressor does no activate


Phil, it may simply be a case that you have the humidity extraction level set to high. Try lowering it to 32 - 35%. If your unit is not equipped with an LED Screen, set the manual control to Maximum.

Also, remove and check the air intake filter, to see if it needs cleaning. And maintain at least a minimum of 12 - 18" of clear air space around the entire unit, while in operation.

Hope this helped you. Please let me know. Thanks.

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.

DE 500P - Fan will not shut off


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.

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
