Favorit ER10

Favorit error code ER10 indicates: Favorit SwissBake / CombiSteam Built-in Pyrolytic Convection Oven: Diagnostic fault code ER10 registered by the microcomputer controller. Built-in oven power control board Darlington relay driver IC output channel breakdown (code ER10).

The primary root cause for Favorit code ER10 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: relay inductive back-EMF spike damaged open-collector transistor stage in ULN2003 driver array. Metrological tolerance verification: driver output pin resistance to ground must be >50 kΩ unasserted; short to ground (<10 Ω) indicates blown IC..

To resolve error code ER10: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: de-energize oven, measure resistance between driver IC output pins and ground with ohmmeter, replace PCB if shorted. 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 ER10 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: relay inductive back-EMF spike damaged open-collector transistor stage in ULN2003 driver array. Metrological tolerance verification: driver output pin resistance to ground must be >50 kΩ unasserted; short to ground (<10 Ω) indicates blown IC. 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.
