Ariston FC

Ariston error code FC indicates: Ariston Hotpoint-Ariston 3D Zone Wash MaxiSpace Dishwasher: Water softener hardness sensor circuit fault FC; salt concentration conductivity measurement signal interrupted..

The primary root cause for Ariston code FC is: On Ariston dishwashers: Salt bridge in brine tank preventing sensor contact, corroded conductivity electrode pins, or disconnected softener wiring harness..

To resolve error code FC: Stir salt container with wooden spoon to break crusts. Add 500ml warm water. Clean electrode pins and check wiring continuity to main control PCB. Hold Start/Reset key for 5 seconds until cycle cancel chime sounds and drain pump completes sump evacuation.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Ariston code FC persists, the physical component causing On Ariston dishwashers: Salt bridge in brine tank preventing sensor contact, corroded conductivity electrode pins, or disconnected softener wiring harness. 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.
