some dehumidifiers will have different codes for each brand. but what that means is that, the bucket on the dehumidifier is full of water, and needs to be dumped. it will fill full of water as it takes the moisture out of the air. try to figure out how to get the bucket out and dumped, then power the system down, an back on and that should reset the codes, and resume normal operation. if that doesn't help Thompson Refrigeration Heating & Cooling
and i could possibly help you further. good luck to ya!
