Arthur Martin iA0

Arthur Martin error code IA0 indicates: Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher: Lower spray arm rotation sensor missing pulses iA0; lower wash arm is stalled or rotation blocked..

The primary root cause for Arthur Martin code IA0 is: On Arthur Martin (Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher) 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. Hold Départ/Pause and Option buttons firmly for 5 seconds until the red indicator extinguishes and service memory resets.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Arthur Martin code IA0 persists, the physical component causing On Arthur Martin (Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher) 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.
