DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Nardi F23
FAQ TREEWhat does error code F23 mean on a Nardi appliance?
Nardi error code F23 indicates: Nardi LSI / LVI / LGI Built-in Stainless Steel Sump Integrated Dishwasher: Operational diagnostic fault code F23 signaled by internal electronics. Condensation active drying fan blower motor winding open circuit or impeller seized (240-320 Ω).
What is the root cause of Nardi error code F23?
The primary root cause for Nardi code F23 is: On Nardi kitchen suites engineered with Bitron wash hydraulics, 2040W flow-through heater (26-28 Ω), 10 kΩ wash NTC, synchronous drain motor (160-220 Ω), and AquaStop float protection: Thermal fuse embedded in fan coil blown from continuous operation, bearing dry, or moisture ingress Multimeter diagnostic parameter: drying fan shaded-pole motor winding nominal 240 Ω to 320 Ω at 20°C; rotor spins freely without resistance..
How do I fix or resolve Nardi error code F23?
To resolve error code F23: 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 drying fan terminals on upper side panel (240-320 Ω) and spin impeller by hand. Inspect spade lugs for signs of heat discoloration. Replace defective component, restore electrical supply, and perform system reset: Close door securely. Hold Program Selection button for 5 seconds while turning power switch ON; release when program LEDs sequence to reset.
Is it safe to clear Nardi error code F23 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Nardi code F23 persists, the physical component causing On Nardi kitchen suites engineered with Bitron wash hydraulics, 2040W flow-through heater (26-28 Ω), 10 kΩ wash NTC, synchronous drain motor (160-220 Ω), and AquaStop float protection: Thermal fuse embedded in fan coil blown from continuous operation, bearing dry, or moisture ingress Multimeter diagnostic parameter: drying fan shaded-pole motor winding nominal 240 Ω to 320 Ω at 20°C; rotor spins freely without resistance. must be inspected or replaced.
How do I test electrical resistance for Nardi code F23 using a multimeter?
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..
What safety protocol must be followed before servicing Nardi code F23?
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.
