Nardi Er22

Nardi error code ER22 indicates: Nardi FEX / FEA / FRA Built-in Electric Multifunction & Pyrolytic Italian Oven: Operational diagnostic fault code Er22 signaled by internal electronics. Cavity circulation convection fan motor winding open circuit or rotor mechanically locked.

The primary root cause for Nardi code ER22 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: Motor shaded-pole winding burned open, caramelised food fats seizing rear bearing, or motor capacitor open Multimeter diagnostic parameter: convection fan motor winding nominal 170 Ω to 220 Ω at 20°C; rotor spins smoothly without axial binding..

To resolve error code ER22: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: measure resistance across convection fan motor terminals (expect 170-220 Ω) and test capacitor if fitted. 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 ER22 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: Motor shaded-pole winding burned open, caramelised food fats seizing rear bearing, or motor capacitor open Multimeter diagnostic parameter: convection fan motor winding nominal 170 Ω to 220 Ω at 20°C; rotor spins smoothly without axial binding. 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.
