How to Fix / Troubleshooting

Safety: Always unplug before inspecting the power cord or internal components.

Checks:

  • Outlet test: Verify the wall socket with another appliance. Reset any tripped breakers or RCDs.
  • Power cord: Inspect the Neff power cord for cuts, kinks, or burn marks. Replace if damaged.
  • Mains filter: Access the mains filter module (often near the cord entry). Look for burn marks or a blown component. Replace the filter if faulty.
  • Control board: If the outlet and cord are good but there is still no power, the main PCB may have failed and should be replaced by a technician.
