Here are some steps you can try:

Check the Hose Connection: Since you mentioned that you have a hose connected, ensure that it's securely attached. Sometimes a loose connection can cause the unit to continue running even when the bucket is full.

Inspect the Drain Bucket and Sensor: Make sure the drain bucket is properly positioned and seated. Additionally, check if there's any debris or dirt blocking the sensor that detects the water level. Clean the sensor if needed.
Reset the Unit: Unplug the dehumidifier from the power source for a few minutes, then plug it back in. This can sometimes reset the control board and resolve any glitches.

Check for Error Codes: You mentioned that the digital display reads "CO." Refer to the user manual or Frigidaire's troubleshooting resources to identify what this error code means. It could provide insights into the issue.
Inspect the Control Panel: Look for any buttons or settings related to continuous mode. While some models may not have a specific switch for continuous mode, there might be a combination of buttons (e.g., holding down two buttons simultaneously) that activates or deactivates it.

Review the User Manual: If you still can't find a solution, consult the user manual that came with your dehumidifier. It should provide specific instructions on how to operate and troubleshoot your model.
If none of these steps resolve the issue, consider reaching out to Frigidaire customer support

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

I believe it is a water tank code. Re-seat the tank, unplug wait 15 seconds and replug the power cord and see if this resolves the error.

Background relating to other possibilities.
When the water bucket reaches its capacity, the bucket switch opens to shut off the dehumidifier. If the bucket switch fails while it is open, it will prevent the dehumidifier from running. To determine if the bucket switch is defective, use a multimeter to test it for continuity. If the bucket switch does not have continuity, replace it.

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

Your question needs to be answered in 3 parts:

1) As per the manual for my Danby Dehumidifier (Model DDR657EE), the unit may not turn on immediately when powered On (it may take a several minutes). So, generally, it would be normal in your case.

2) Danby's Consumer Help Line (1-800-263-2629) is always busy. So, I called their General number: 419-425-8627. The receptionist transferred my call to their Service dept. My call was answered in 2 minutes.

The Service Rep. described the following code for my dehumidifier model (DDR657EE):
P1 = Defrosting: the unit will go into Defrost mode periodically to ensure that the parts are working at the right operating temperature. It should be in Defrost (P1) mode for only a brief period of time. If the unit is in Defrost (P1) mode continuously for a couple of hours (or more), then you should call Danby Service for further assistance.

He had no documentation of a P2 code for my model.

He also described other General Codes (applicable to most Dehumidifier/Humidifier models):
E1 = Not enough water
E2 = Not draining
E3 = Water temperature too cool
E4 = Overflow Switch activated
E6 / E7 = Problem with Temperature Sensor

So, generally, if you see P1 periodically (for brief periods), then it would be normal.

3) Since your unit keeps running (continuously) and there is no water in the bucket, then you should call Danby ServiceI for additional assistance - it seems defective for this reason.

I hope that helps.
