Nardi Er29

Nardi error code ER29 indicates: Nardi FEX / FEA / FRA Built-in Electric Multifunction & Pyrolytic Italian Oven: Operational diagnostic fault code Er29 signaled by internal electronics. Water reservoir drawer magnetic float reed sensor open circuit / reservoir drawer not detected.

The primary root cause for Nardi code ER29 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: Float magnet missing from drawer, reed switch glass tube broken, or wiring harness disconnected Multimeter diagnostic parameter: reed sensor continuity <0.2 Ω when reservoir is inserted and filled; open circuit (>10 MΩ) when removed..

To resolve error code ER29: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: test reed switch continuity on chassis frame with drawer inserted and check magnetic float buoyancy. 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 ER29 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: Float magnet missing from drawer, reed switch glass tube broken, or wiring harness disconnected Multimeter diagnostic parameter: reed sensor continuity <0.2 Ω when reservoir is inserted and filled; open circuit (>10 MΩ) when removed. 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.
