De Dietrich Er12

De Dietrich error code ER12 indicates: De Dietrich ICS (Intelligent Cooking System) / Fascination / Corium Pyrolytic Oven: Lower heating sole element relay fault Er12; bottom oven cavity continues heating unchecked regardless of thermostat setting..

The primary root cause for De Dietrich code ER12 is: On De Dietrich built-in ovens featuring ICS sensor-guided automated culinary cooking, PT500 platinum thermal probe (~540 Ω at 20°C), and 480°C Pyro-Turbo cleaning: Welded relay contacts on lower bake heating circuit on main power board..

To resolve error code ER12: Isolate breaker. Measure bottom bake element resistance (~35–45 Ω). Measure continuity across bake relay contacts with power off (must be open). Rotate rotary knob to zero, disconnect power at the master breaker panel for 90 seconds, re-engage and validate time on the ICS interface.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if De Dietrich code ER12 persists, the physical component causing On De Dietrich built-in ovens featuring ICS sensor-guided automated culinary cooking, PT500 platinum thermal probe (~540 Ω at 20°C), and 480°C Pyro-Turbo cleaning: Welded relay contacts on lower bake heating circuit on main power board. 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.
