Nardi Er24

Nardi error code ER24 indicates: Nardi FEX / FEA / FRA Built-in Electric Multifunction & Pyrolytic Italian Oven: Operational diagnostic fault code Er24 signaled by internal electronics. Microcontroller internal software watchdog reset loop or DC logic voltage ripple disturbance.

The primary root cause for Nardi code ER24 is: On Nardi kitchen suites engineered with PT500 temperature sensor (540 Ω at 20°C), shaded-pole tangential cooling motor, 2200W circular turbo heater, motorized latch, and electronic relay board: Filter capacitor dried out in switch-mode power supply, high electrical noise from relay arc, or MCU failure Multimeter diagnostic parameter: +5.0V DC regulated logic rail stable within ±2% (4.90V to 5.10V DC); AC ripple voltage <30 mV RMS..

To resolve error code ER24: 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 output voltage and AC millivolt ripple across logic filter capacitors on main control board. Inspect spade lugs for signs of heat discoloration. Replace defective component, restore electrical supply, and perform system reset: Turn mode dial to 0. Press and hold Clock and Stop buttons for 5 seconds until buzzer beeps twice, resetting internal microprocessor error log.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Nardi code ER24 persists, the physical component causing On Nardi kitchen suites engineered with PT500 temperature sensor (540 Ω at 20°C), shaded-pole tangential cooling motor, 2200W circular turbo heater, motorized latch, and electronic relay board: Filter capacitor dried out in switch-mode power supply, high electrical noise from relay arc, or MCU failure Multimeter diagnostic parameter: +5.0V DC regulated logic rail stable within ±2% (4.90V to 5.10V DC); AC ripple voltage <30 mV RMS. 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.
