Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the unit before opening any covers.
- Step 1 – Hard reset: Unplug the dehumidifier for at least 15 minutes to allow capacitors to discharge. Plug back in and attempt to start.
- Step 2 – Check power quality: Plug the unit directly into a properly grounded wall outlet (no extension cords or power strips). Voltage drops or surges can trigger memory errors.
- Step 3 – Inspect control board connections: Remove the rear or top cover to access the main PCB. Reseat all harness connectors firmly.
- Step 4 – Board replacement: If F0 persists, the EEPROM or microcontroller on the board is likely damaged. Replace the main control board with a Danby-compatible part.
When to call a technician: F0 almost always requires board replacement, which is best handled by a qualified technician.
