Favorit iA0

Favorit error code IA0 indicates: Favorit SwissLine / DIVA SilentTech Fully Integrated Precision Dishwasher: Diagnostic fault code iA0 registered by the microcomputer controller. Dishwasher lower wash spray arm rotation sensor feedback missing or spray arm stalled (code iA0).

The primary root cause for Favorit code IA0 is: On Favorit SwissLine and European precision appliances built for high durability engineered with Hydro-Flow wash circulation pump with tachometer (80-120 Ω), 2000W flow-through heater (25-28 Ω), electronic analog pressure transmitter, turbidity optic sensor, and AquaStop base pan float switch: tall dish plate obstructing spray arm path, permanent magnet missing from arm tip, or Hall sensor defect. Metrological tolerance verification: Hall effect sensor output generates 1 pulse per revolution; supply 5.0V DC; arm rotates >25 RPM under wash..

To resolve error code IA0: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: rearrange dishes to clear lower spray arm, check magnet presence with iron pin, and measure Hall sensor 5V DC rail. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Press and hold Start/Reset button for 4 seconds until drain pump initiates, then turn off power for 60 seconds to clear active error code.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Favorit code IA0 persists, the physical component causing On Favorit SwissLine and European precision appliances built for high durability engineered with Hydro-Flow wash circulation pump with tachometer (80-120 Ω), 2000W flow-through heater (25-28 Ω), electronic analog pressure transmitter, turbidity optic sensor, and AquaStop base pan float switch: tall dish plate obstructing spray arm path, permanent magnet missing from arm tip, or Hall sensor defect. Metrological tolerance verification: Hall effect sensor output generates 1 pulse per revolution; supply 5.0V DC; arm rotates >25 RPM under wash. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

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.
