Sauter F04

Sauter error code F04 indicates: Sauter Saveurs / Confort / Amphora / SFP Pyrolytic Oven: Pyrolytic door lock motor drive failure F04; latch actuator fails to reach locked position within 60 seconds..

The primary root cause for Sauter code F04 is: On Sauter ovens featuring Saveurs gentle convection airflow, Conseil Température cooking guide, and Amphora enamel heat reflection: Open actuator motor coil (~4.8 kΩ), cracked reduction gears, or door hook misalignment..

To resolve error code F04: Check door latch motor coil resistance (~4.8 kΩ). Verify latch mechanism rotates freely without binding against chassis sheet metal. Turn selector to Off, drop power at the branch breaker for 60 seconds, restore supply and touch the clock icon to recalibrate.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Sauter code F04 persists, the physical component causing On Sauter ovens featuring Saveurs gentle convection airflow, Conseil Température cooking guide, and Amphora enamel heat reflection: Open actuator motor coil (~4.8 kΩ), cracked reduction gears, or door hook misalignment. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

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.
