Favorit ER02

Favorit error code ER02 indicates: Favorit SwissBake / CombiSteam Built-in Pyrolytic Convection Oven: Diagnostic fault code ER02 registered by the microcomputer controller. Built-in oven cavity PT1000 platinum RTD temperature sensor circuit shorted (code ER02).

The primary root cause for Favorit code ER02 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: mineral wool insulation glass fibers degraded allowing silicone lead conductors to touch grounded chassis. Metrological tolerance verification: PT1000 RTD resistance nominal 1079 Ω at 20°C; measured resistance <200 Ω indicates catastrophic short circuit..

To resolve error code ER02: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: inspect sensor leads along cavity wall, test resistance across pins (<200 Ω replace), verify wire insulation. 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 ER02 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: mineral wool insulation glass fibers degraded allowing silicone lead conductors to touch grounded chassis. Metrological tolerance verification: PT1000 RTD resistance nominal 1079 Ω at 20°C; measured resistance <200 Ω indicates catastrophic short circuit. 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.
