Sauter Er04

Sauter error code ER04 indicates: Sauter Saveurs / Confort / Amphora / SFP Pyrolytic Oven: Pyrolytic door lock mechanism timeout Er04; motorized latch fails to lock the oven door when initiating self-clean mode..

The primary root cause for Sauter code ER04 is: On Sauter built-in ovens featuring Saveurs gentle convection airflow, Conseil Température cooking guide, and Amphora enamel heat reflection: Jammed door latch cam mechanism, broken lock gear motor coil (~4.5–6.0 kΩ), or pitted locking microswitch..

To resolve error code ER04: Inspect door lock latch above door cavity. Measure lock motor winding resistance (~4.5–6.0 kΩ). Verify microswitch contacts close (~0 Ω) when locked. 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 ER04 persists, the physical component causing On Sauter built-in ovens featuring Saveurs gentle convection airflow, Conseil Température cooking guide, and Amphora enamel heat reflection: Jammed door latch cam mechanism, broken lock gear motor coil (~4.5–6.0 kΩ), or pitted locking microswitch. 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.
