De Dietrich AS

De Dietrich error code AS indicates: De Dietrich Piano Zoneless / Horizone / DPI Induction Cooktop: Auto-Stop safety timeout triggered AS; all induction cooking zones shut down automatically after liquid spillover or prolonged cooking..

The primary root cause for De Dietrich code AS is: On De Dietrich cooktops utilizing Piano full-surface zoneless induction matrix, 16-level power modulation, and Boil function boilover prevention: Boiling liquid overflowed onto capacitive touch keys, metallic utensil left on keys, or unattended cooking timeout reached..

To resolve error code AS: Remove hot cookware and wipe glass surface completely clean and dry with a dry cloth. Touch the master On/Off key to resume normal cooking. Clear the ceramic surface, turn off the dedicated breaker for 60 seconds, restore supply and touch the Key Lock sensor for 5 seconds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if De Dietrich code AS persists, the physical component causing On De Dietrich cooktops utilizing Piano full-surface zoneless induction matrix, 16-level power modulation, and Boil function boilover prevention: Boiling liquid overflowed onto capacitive touch keys, metallic utensil left on keys, or unattended cooking timeout reached. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..

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.
