Nardi C30

Nardi error code C30 indicates: Nardi PVF / PV43 Touch Control Induction & Electronic Flame Gas Cooktop: Operational diagnostic fault code C30 signaled by internal electronics. Main power PCB relay coil power supply rail collapse (+24V DC / +12V DC rail dropped below 8.0V).

The primary root cause for Nardi code C30 is: On Nardi kitchen suites engineered with planar induction coils, 100 kΩ surface thermistors, IGBT transistors with fast recovery diodes, 12V fan tachometer, and 230V spark pulse generators: Short-circuit in one relay coil dragging down rail, filter capacitor shorted, or regulator diode blown Multimeter diagnostic parameter: relay supply rail nominal 12.0V DC or 24.0V DC ±5%; load drop must remain <0.5V DC when all relays energize..

To resolve error code C30: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: measure DC voltage across relay coil supply capacitors on power PCB and check individual relay coil resistances. Inspect spade lugs for signs of heat discoloration. Replace defective component, restore electrical supply, and perform system reset: Isolate hob at the electrical fuse board for 90 seconds. Restore power and press the ON/OFF key three times within 5 seconds to clear faults.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Nardi code C30 persists, the physical component causing On Nardi kitchen suites engineered with planar induction coils, 100 kΩ surface thermistors, IGBT transistors with fast recovery diodes, 12V fan tachometer, and 230V spark pulse generators: Short-circuit in one relay coil dragging down rail, filter capacitor shorted, or regulator diode blown Multimeter diagnostic parameter: relay supply rail nominal 12.0V DC or 24.0V DC ±5%; load drop must remain <0.5V DC when all relays energize. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

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.
