The use and care manual for the FFAD2233W1 lists AS or ES as a failed sensor, EC as an operating condition problem where outlet voltage and room temperature should be checked, and CO as the continuous mode indicator rather than an error.
That makes this model easy to troubleshoot at owner level: CO is normal, the filter light appears after about 250 hours, and EC often clears once the unit is on a proper outlet in a room within the stated temperature range. AS or ES that persists needs service.
Key Features
- Dehumidifier listed at about 22 pints per day
