Basement Dehumidifier keeps throwing 'EC' code

[Chevy-SS]

I have a 6-year old Frigidaire dehumidifier in my basement, model # FFAP5033W1. It has started throwing an 'EC' trouble code. I can reset it (by unplugging) and it will run for a bit, but I don't think it's actually working. Then the code will come back and it will stop. It has built-in pump to evacuate the water (drain line is clear), the water tank is empty. And the air filter is clean.

I'm wondering if something inside may be blocked by dirt, dust or even a spider web? Before I start getting aggressive, I figured I'd ask here. There seems to be an answer on this Forum for every single home/garage related question, no matter how obscure.....

Thanks for any help or tips!

EC usually a problem with refrigeration system. Non repairable more than likely short on refrigerant if the fan is running.

I had an EC code on one of the frigidaire clones (can't remember the brand) several years ago. I was never able to figure out what was going wrong. Maybe a new humidistat? I remember opening up the unit and seeing a very simple humidistat hanging in the air stream. If a humidistat can be had cheap, maybe??

might be sensor issue.
