Just called Frigidaire Dehumidifier product support 1-800-374-4432 (by electrolux), 'EC' means "sealed system fault" and basically unrepairable. If your unit still under Frigidaire 5 year warranty, they ask you cut the cord, send a photo of the cut cord and the unit, plus serial number tag photo by email to verify you have the unit. They'll send you a new one once they received the email with all proper identifications

This is more of a tip since I have not actually fixed anything yet. As a test, remove the upper front cover where the buttons and displays are. (2 screws on the bottom then pull off a the plastic snaps) Inside the case on the far left, there is a piece of crimped copper tubing, open on the top end, welded to the refrigerant line, with a black sleeve covering 2 wires out the bottom end. This is a thermistor. I CAREFULLY applied heat with a butane lighter (the mini torch kind, not the "candle flame" kind), taking care not to burn anything. I applied ONLY enough to make it slightly warm to the touch. Do not think of melting anything, as this is not the purpose. Applying too much heat could damage the thermistor. With the bucket in place, the unit started right up. After I did this, it failed again in a few minutes, so I heated it again, and thus verifying it as the source. I have done it a third time, never getting it much over room temperature, and it is still running after almost an hour after doing nothing else. Since this temperature sensing is an analog function to the microcontroller that runs everything, the fault could be any bad connection or solder joint along the way from this thermister to the controller. But is sure appears something in thermistor. I hope my description is complete and clear. Good luck.

Hi
The
tank may be full. Your dehumidifier has a safety device that turns off
the dehumidifier when the water tank is full. Usually the tank itself
either presses against a switch or there's a device connected to the
tank that triggers a switch when the tank is in place and full.
If
you've emptied the tank and the unit doesn't run, inspect the place
where the tank rests to see if there's a switch or mechanism that's not
being activated. You may be able to turn it on with a simple flick of
your finger.
Take care.

That depends on the manufacturer and in what mode you are operating it. If it's Continuous Mode. Yes, the fan will continue to run, as it's recirculating the air, in an effort to determine if and when the humidity level rises. Then the compressor will turn ON to extract the humidity.
Also, most units will do this if they are running thru the Defrost Cycle. This happens when the cooling coils frost over. It to, is a normal cycle.
So, if you are operating the dehumidifier in Continuous Mode, it's acceptable.

Hope this helped you. Please let me know. Thanks.
Good Morning Mark, thank you for your post!
I see that your Frigidaire dehumidifier is displaying an error code of "ES" and you would like to the meaning of that error code. The "ES" error code stands for evaporator thermistor error. This could be a possible problem with your control panel, thermistor, or a wiring harness. I would recommend contacting your manufacturer for further assistance with your dehumidifier. Best of luck! -Matt
Hey Art Miner, thank you for your post!
I understand that your dehumidifier is not operating properly. You should put it on a continuous drain mode to see if it will continue to pull moisture. Could you please provide feedback to what your appliance is doing once set to a continuous drain? -Matt
Hello Diane Weber, thank you for your inquiry!
I see that you have recently purchased a Frigidaire dehumidifier and the display is not working properly. When you returned the original appliance did they test it in store to see if it worked? Are you using any type of extension cord or surge protector on the appliance? With this additional information I can better assist you. -Matt
