AEG iA0

AEG error code IA0 indicates: AEG Favorit / ProClean / ComfortLift Series: Lower spray arm rotation sensor missing pulses iA0; lower wash arm is stalled or rotation blocked..

The primary root cause for AEG code IA0 is: On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Tall plates, cutting boards, or cutlery handles protruding through basket blocking spray arm, missing arm magnet, or defective Hall sensor..

To resolve error code IA0: Rearrange lower basket loading so dishes do not contact spray arm. Inspect lower spray arm tip to confirm embedded magnet is present. Rotate selector to 12 o'clock (OFF), press and hold Start/Pause and Exit simultaneously for 4 seconds until the diagnostic LED sequence resets error memory.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if AEG code IA0 persists, the physical component causing On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Tall plates, cutting boards, or cutlery handles protruding through basket blocking spray arm, missing arm magnet, or defective Hall sensor. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

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.
