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

An E3 error code is a Sensor Shutdown Failure. You will need to contact Haier Customer Support for an explanation on which sensor it is and how to solve the problem.

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 on panel, dehumidifier will not start

DE500P does not run and shows error code E3. What part do I need to replace and where can I get it?

I am searching for a resolution to the E3 code (same init) and happened upon this request. The manual can be downloaded from DeLonghi.com but that advises you to call the service center.

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
