Possible Causes

How to Fix / Troubleshooting
Safety: Disconnect power before any electrical work.
Steps to address E16:
- Power reset: Unplug the wine cooler for at least 15 minutes to allow capacitors to discharge, then reconnect and see if the error clears.
- Factory reset (if available): Consult the user manual for a key combination to reset settings to factory defaults and attempt this after power is restored.
- Check power quality: Ensure the cooler is connected directly to a properly grounded outlet, not through an undersized extension cord or multi-plug adapter.
- Board replacement: If E16 persists, the memory section of the main control PCB is likely defective. Replace the main control PCB with a Neff-approved part; this is typically a technician-level repair.
