Nardi Er10

Nardi error code ER10 indicates: Nardi FEX / FEA / FRA Built-in Electric Multifunction & Pyrolytic Italian Oven: Operational diagnostic fault code Er10 signaled by internal electronics. Heating element power relay contacts welded shut or feedback sensing circuit detects closed contact.

The primary root cause for Nardi code ER10 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: High inrush current arc pitted and fused relay contacts, or driving transistor shorted in conduction Multimeter diagnostic parameter: relay contact resistance must be infinite (>10 MΩ) when coil is unpowered; 0.0 Ω indicates welded contact..

To resolve error code ER10: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: de-solder relay or isolate PCB traces and test resistance between normally-open switch terminals. 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 ER10 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: High inrush current arc pitted and fused relay contacts, or driving transistor shorted in conduction Multimeter diagnostic parameter: relay contact resistance must be infinite (>10 MΩ) when coil is unpowered; 0.0 Ω indicates welded contact. 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.
