Rosieres Er01

Rosieres error code ER01 indicates: Rosières Sublime / Origine / Paul Bocuse Pyrolytic Oven: Cavity temperature sensor open circuit Er01; electronic controller reads infinite resistance from the PT500 / PT1000 oven probe..

The primary root cause for Rosieres code ER01 is: On Rosières ovens utilizing French culinary precision thermal regulation, Paul Bocuse pyrolytic cavity, and GIAS Cuore microcomputer controller: Broken platinum resistor probe inside cavity, heat-damaged silicone wiring behind rear insulation, or loose PCB terminal..

To resolve error code ER01: Isolate power at breaker. Disconnect sensor plug at rear. Measure probe resistance (~538 Ω for PT500 or ~1078 Ω for PT1000 at 20°C). Replace if infinite. Return oven selectors to 0, switch off the kitchen circuit breaker for 60 seconds, re-engage and reset the rotary clock timer.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Rosieres code ER01 persists, the physical component causing On Rosières ovens utilizing French culinary precision thermal regulation, Paul Bocuse pyrolytic cavity, and GIAS Cuore microcomputer controller: Broken platinum resistor probe inside cavity, heat-damaged silicone wiring behind rear insulation, or loose PCB terminal. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

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.
