Arthur Martin E5A

Arthur Martin error code E5A indicates: Arthur Martin Electrolux AWF Series / Silence Plus Washer: Inverter module heat sink overheating alarm E5A; IGBT thermal sensor exceeds 88°C threshold..

The primary root cause for Arthur Martin code E5A is: On Arthur Martin (Arthur Martin Electrolux AWF Series / Silence Plus Washer) models: Inverter housing air vents blocked with lint and dust, dried thermal paste between IGBT module and aluminum heat sink, or excessive ambient heat..

To resolve error code E5A: Vacuum dust from inverter module aluminum heat sink fins. Reapply thermal grease between power bridge and heat sink if detached. 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 E5A persists, the physical component causing On Arthur Martin (Arthur Martin Electrolux AWF Series / Silence Plus Washer) models: Inverter housing air vents blocked with lint and dust, dried thermal paste between IGBT module and aluminum heat sink, or excessive ambient heat. 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.
