DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Neff E5116
FAQ TREEWhat does error code E5116 mean on a Neff appliance?
Neff error code E5116 indicates: Neff N 50 / N 70 / N 90 Slide&Hide® & CircoTherm® Pyrolytic Oven with ShiftControl: Combi-microwave inverter magnetron heater open circuit E5116; magnetron filament open or high-voltage inverter output missing..
What is the root cause of Neff error code E5116?
The primary root cause for Neff code E5116 is: On Neff ovens: Burned-out filament in 2M261 magnetron tube (nominal < 0.2 Ω), blown high-voltage fuse, or defective resonant inverter board..
How do I fix or resolve Neff error code E5116?
To resolve error code E5116: DANGER: Disconnect mains and discharge high-voltage capacitor. Measure magnetron filament resistance across terminals (< 0.2 Ω; open if > 1 Ω). Turn oven off, hold 'i' Info and Clock icons simultaneously on ShiftControl panel for 4 seconds, or cycle mains breaker.
Is it safe to clear Neff error code E5116 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Neff code E5116 persists, the physical component causing On Neff ovens: Burned-out filament in 2M261 magnetron tube (nominal < 0.2 Ω), blown high-voltage fuse, or defective resonant inverter board. must be inspected or replaced.
How do I test electrical resistance for Neff code E5116 using a multimeter?
Set a digital multimeter to ohms (Ω). Disconnect power and test Immersion / Air Heating Element & Klixon Thermostat across Between element terminals (unwired). Insulation to earth casing: >20MΩ (OL). Expected nominal reading is 25Ω–28Ω (230V / 2000W) / <0.5Ω (Safety Klixon closed). Tolerance: Formula R = V²/P (±5%). Any earth leakage reading below 2MΩ will trip the domestic 30mA RCD breaker..
What safety protocol must be followed before servicing Neff code E5116?
Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
