Favorit ER01

Favorit error code ER01 indicates: Favorit SwissBake / CombiSteam Built-in Pyrolytic Convection Oven: Diagnostic fault code ER01 registered by the microcomputer controller. Built-in oven cavity PT1000 platinum RTD temperature sensor circuit open (code ER01).

The primary root cause for Favorit code ER01 is: On Favorit SwissLine and European precision appliances built for high durability engineered with PT1000 platinum RTD probe (1080 Ω at 20°C), 2400W convection circular element (22-25 Ω), radial exhaust cooling turbine (160-220 Ω), and motorized door interlock latch: internal platinum thin-film element fractured by thermal cycling, or glass-fiber lead wire severed. Metrological tolerance verification: PT1000 RTD resistance 1079 Ω at 20°C, 1385 Ω at 100°C, 1758 Ω at 200°C; resistance >2500 Ω indicates open..

To resolve error code ER01: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: remove rear oven chassis cover, unplug PT1000 sensor header, and measure resistance directly with calibrated ohmmeter. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Turn temperature knob to Off. Press and hold Clock and Stop buttons for 5 seconds until confirmation tone sounds, wiping error state from EEPROM.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Favorit code ER01 persists, the physical component causing On Favorit SwissLine and European precision appliances built for high durability engineered with PT1000 platinum RTD probe (1080 Ω at 20°C), 2400W convection circular element (22-25 Ω), radial exhaust cooling turbine (160-220 Ω), and motorized door interlock latch: internal platinum thin-film element fractured by thermal cycling, or glass-fiber lead wire severed. Metrological tolerance verification: PT1000 RTD resistance 1079 Ω at 20°C, 1385 Ω at 100°C, 1758 Ω at 200°C; resistance >2500 Ω indicates open. 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.
