Favorit ER05

Favorit error code ER05 indicates: Favorit SwissBake / CombiSteam Built-in Pyrolytic Convection Oven: Diagnostic fault code ER05 registered by the microcomputer controller. Built-in oven pyrolytic high-temperature door lock motorized latch actuator timeout (code ER05).

The primary root cause for Favorit code ER05 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: synchronous latch motor gear reduction teeth broken, latch hook jammed by thermal warp, or motor coil open. Metrological tolerance verification: latch drive motor coil resistance 1.8 kΩ to 2.5 kΩ at 20°C (230V AC motor); lock microswitch contact <0.2 Ω..

To resolve error code ER05: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: inspect door latch mechanism above cavity opening, measure motor coil resistance (~2.1 kΩ), verify switch. 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 ER05 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: synchronous latch motor gear reduction teeth broken, latch hook jammed by thermal warp, or motor coil open. Metrological tolerance verification: latch drive motor coil resistance 1.8 kΩ to 2.5 kΩ at 20°C (230V AC motor); lock microswitch contact <0.2 Ω. 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.
