Sauter F8

Sauter error code F8 indicates: Sauter Spiromatic / Horizone / SPI Rotary Induction Hob: Continuous pan sensing resonance failure F8; induction coil pulses loudly but cannot sustain stable magnetic field coupling..

The primary root cause for Sauter code F8 is: On Sauter cooktops utilizing Spiromatic signature circular rotary capacitive touch sliders, Horizone expandable zone, and 14 power presets: Cookware with non-uniform sandwich composite base, cracked resonance capacitor bank on power PCB, or burned Litz coil wire..

To resolve error code F8: Switch to a solid heavy cast iron skillet to test coil coupling. Inspect resonance capacitors on PCB for bulging or scorch marks. Wipe down ceramic cooktop, open isolation switch for 60 seconds, reclose and hold the Spiromatic Center Pad for 5 seconds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Sauter code F8 persists, the physical component causing On Sauter cooktops utilizing Spiromatic signature circular rotary capacitive touch sliders, Horizone expandable zone, and 14 power presets: Cookware with non-uniform sandwich composite base, cracked resonance capacitor bank on power PCB, or burned Litz coil wire. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test PCB Power Supply Rails & DC Bus Filter Capacitors across Across SMPS output electrolytic capacitors on low-voltage side (test bench verification). Expected nominal reading is Low-voltage rails: +5.0V DC (Logic), +12.0V DC (Relays), +3.3V DC (MCU). Relay coils: 200Ω–450Ω.. Tolerance: DC rail ripple must remain <50mV. Direct continuity (0Ω) across DC bus rails indicates dead short..

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.
