Arthur Martin E12

Arthur Martin error code E12 indicates: Arthur Martin Electrolux AWF Series / Silence Plus Washer: Condenser water fill error E12 on washer-dryer; cold water injection for condensation fails during dry cycle..

The primary root cause for Arthur Martin code E12 is: On Arthur Martin (Arthur Martin Electrolux AWF Series / Silence Plus Washer) models: Secondary solenoid valve for drying condenser open-circuit (expected 3.8–4.4 kΩ), lime buildup in condenser nozzle, or dedicated triac failure on main PCB..

To resolve error code E12: Measure resistance across the drying condenser solenoid valve coil (expected ~4 kΩ). Clean nozzle orifice in rear air duct. 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 E12 persists, the physical component causing On Arthur Martin (Arthur Martin Electrolux AWF Series / Silence Plus Washer) models: Secondary solenoid valve for drying condenser open-circuit (expected 3.8–4.4 kΩ), lime buildup in condenser nozzle, or dedicated triac failure on main PCB. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Solenoid Valve Coil / Aquastop Pneumatic Valve across Across coil spade terminals (disconnect harness first). Expected nominal reading is 3.5kΩ–4.5kΩ (Standard 230V) / 2.0kΩ–4.2kΩ (Aquastop). Tolerance: ±10%. Open circuit (OL) indicates burned solenoid coil. Flowmeter turbine reed switch pulses on flow..

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.
