Rosieres FC0

Rosieres error code FC0 indicates: Rosières RLF / RLE Pro Inverter Washing Machine: Inverter drive communication loss FC0; main control module loses communication handshake with motor inverter module..

The primary root cause for Rosieres code FC0 is: On Rosières washers utilizing Pro Inverter quiet direct drive system, GIAS electronic platform, and balance sensor control: Disconnected communication cable, corroded pin terminals, or power supply failure on the motor inverter board..

To resolve error code FC0: Inspect multi-wire serial cable between main PCB and inverter module. Re-seat connectors and check pin tension. Verify low-voltage DC rails. Set selector to stop position, press and hold Start and Spin buttons for 5 seconds until warning lights blink sequentially, then turn off.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Rosieres code FC0 persists, the physical component causing On Rosières washers utilizing Pro Inverter quiet direct drive system, GIAS electronic platform, and balance sensor control: Disconnected communication cable, corroded pin terminals, or power supply failure on the motor inverter board. 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.
