How to Fix / Troubleshooting

Safety: Unplug the appliance before accessing the control panel.

Steps:

  • Review user manual: Confirm correct procedure for selecting and setting each zone; some models require pressing a zone button before adjusting.
  • Power reset: Disconnect power for 10–15 minutes to clear any software glitches.
  • Inspect UI connections: Remove the control panel and check that all connectors for zone control are firmly seated.
  • Replace UI PCB: If independent control still does not work, the user interface or main control PCB may be defective and should be replaced with Neff-specific parts.
