Rosieres ER31

Q: What does error code ER31 mean on a Rosières appliance?

Rosières error code ER31 indicates: Rosières RVI / RPI Piano de Cuisson & Induction Cooktop: Power board configuration data corrupted ER31; generator module variant coding table does not match cooktop model setup..

Q: What is the root cause of Rosières error code ER31?

The primary root cause for Rosières code ER31 is: On Rosières cooktops featuring Piano de Cuisson induction generator, heavy-duty electromagnetic coils, and high-temperature thermal safety module: Unprogrammed replacement power board installed, electrical line surge, or corrupted non-volatile memory block..

Q: How do I fix or resolve Rosières error code ER31?

To resolve error code ER31: Enter service configuration mode via touch button sequence and re-program the exact model code from appliance rating plate. Clear pan from hob surface, turn off electrical isolator for 60 seconds, turn back on and press Key Lock sensor for 5 seconds.

Q: Is it safe to clear Rosières error code ER31 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Rosières code ER31 persists, the physical component causing On Rosières cooktops featuring Piano de Cuisson induction generator, heavy-duty electromagnetic coils, and high-temperature thermal safety module: Unprogrammed replacement power board installed, electrical line surge, or corrupted non-volatile memory block. must be inspected or replaced.

Q: How do I test electrical resistance for Rosières code ER31 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test PCB Power Supply Rails & DC Bus Filter Capacitors across Across SMPS output electrolytic capacitors on low-voltage side (test bench verification). Expected nominal reading is Low-voltage rails: +5.0V DC (Logic), +12.0V DC (Relays), +3.3V DC (MCU). Relay coils: 200Ω–450Ω.. Tolerance: DC rail ripple must remain <50mV. Direct continuity (0Ω) across DC bus rails indicates dead short..

Q: What safety protocol must be followed before servicing Rosières code ER31?

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.

1. Pre-Intervention Electrical Safety Protocols

!High-Voltage Safety Protocol: Disconnect 230V power before unplugging edge connectors or removing PCB.
!High Voltage DC Warning: Wait at least 5 minutes for SMPS and inverter filter capacitors (up to 380V DC) to discharge safely.
!Electrostatic Discharge (ESD): Ground yourself to the metal chassis or wear an antistatic wrist strap before touching circuit tracks.

3. Preliminary Mechanical & Visual Checks

Inspect PCB tracks with a magnifying glass for blown triacs, darkened copper tracks, or cold solder joints on power relays.
Check electrolytic capacitors for bulging tops or leaked electrolyte residue around pins.
Verify edge connector locking clips are intact and pins are free of vibration fretting corrosion.
