Possible Causes

Corrupted firmware on main control board, Power surge damage to microcontroller, Loose control board connectors, Defective main PCB

Safety: Unplug the unit before accessing internal components.

Hard reset: Unplug the dehumidifier for at least 15 minutes to fully discharge the control board, then plug back in.
Check wiring: Remove the control panel and inspect all harnesses going to the main PCB. Reseat each connector firmly.
Surge protection: If F0 occurred after a storm or outage, consider using a surge protector in the future.
Replace main PCB: If F0 persists, the main control board is likely faulty and must be replaced with the correct Comfee part number.
