wow I get this question A lot ... things to ck first
1- control setting = less than room measurement for humidity , if your unit does not tell you rooms rh% consider buying a external %rh meter that you can place elsewhere in room there not that expensive to buy
2 unit working properly ? look for bucket full lights (it doesn't allways mean bucket is full) fault light or codes ? filters clean and new looking ?
3 if unit sounds if its running did you know that most dehumidifiers nowdays have two fans in them , could be you hear one running and not the other , this will prevent the unit from working correctly and some units don't let you know theres a fault with it (poorly designed my opinion ) , use a flashlight give it a good lookover you'd be surprised what you can find with one of those

I have the exact same problem. It is not related to ambient temperature in my case. Would like to hear a solution also.

CO just means it is in continuous mode, that is not a fault. It may take quite a few days to settle the humidity.
The codes are AS or ES which indicate sensor faults

Hello Friend, this is Z. Thank you for allowing me to assist you!

If you are receiving an error code AS, your dehumidifier is experiencing a sensor failure. Because it is a smaller appliance, repairs are often more costly than the actual product replacement. Is your dehumidifier still in warranty? If so, you might want to reach out directly to the manufacturer to determine the coverage on your dehumidifier and the procedures to any potential remedy in that regard. Best of luck!

Probe fault? Temperature sensing probe may have loose connection or water in the tip.

If you get a fault code CH 01, check the posting for that solution and see if it helps.

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.
