Rosieres ER47

Rosieres error code ER47 indicates: Rosières RVI / RPI Piano de Cuisson & Induction Cooktop: LIN-Bus communication between touch controller and power inverter module missing ER47; transmission timeout error..

The primary root cause for Rosieres code ER47 is: On Rosières cooktops utilizing Piano de Cuisson induction generator, heavy-duty electromagnetic coils, and high-temperature thermal safety module: Unseated communication connector, broken wire in wiring loom, or damaged LIN transceiver IC on either board..

To resolve error code ER47: Inspect wiring harness connecting touch interface to induction generator module. Verify pin continuity and terminal retention force. Clear pan from hob surface, turn off electrical isolator for 60 seconds, turn back on and press Key Lock sensor for 5 seconds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Rosieres code ER47 persists, the physical component causing On Rosières cooktops utilizing Piano de Cuisson induction generator, heavy-duty electromagnetic coils, and high-temperature thermal safety module: Unseated communication connector, broken wire in wiring loom, or damaged LIN transceiver IC on either 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.
