De Dietrich Er11

De Dietrich error code ER11 indicates: De Dietrich ICS (Intelligent Cooking System) / Fascination / Corium Pyrolytic Oven: Upper heating grill element relay fault Er11; top grill element glows red continuously without cooking program active..

The primary root cause for De Dietrich code ER11 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 or arced grill power relay contacts on the main power relay circuit board..

To resolve error code ER11: Disconnect mains breaker immediately. Measure grill element resistance (~22–26 Ω). Test relay contacts with power off; replace power relay PCB if shorted. 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 ER11 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 or arced grill power relay contacts on the main power relay circuit 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.
